EXPLORATION

In 1964, five exploratory wells were drilled in Florida, as
shown in figure 1. Four of these tests have been plugged and
abandoned, and the fifth was the discovery well for the Sunoco-
Felda field. A brief tabulation of these wells is presented in table
1. For comparison the exploratory footage drilled in the three
proceeding years was 37,712 feet in 1963, 16,378 feet in 1962
and 87,737 feet in 1961.

Well sheets on the tests listed in table 1 are provided in
appendix 1. Though Cross Sections A-A' and B-B' (figs. 4 and 5)
do not show any of the wells drilled in the' Felda area of Hendry
County by the Sun Oil Company, these sections do include all
of the deep wells in the Felda area completed prior to the drilling
of the Sun wells. Also, appendix 2 is a summary of historic and
economic aspects of Sun's activities in Florida disclosed by Mr.
Tom F. Hill, Manager of the Southwest Production Division of
the Sun Oil Company, during a press conference held on October
9, 1964, the date the discovery well for the new field was tested.

A discussion of the three exploratory wells drilled in Santa
Rosa County, listed in chronological order, follows:

Santa Rosa County

The Young Drilling Company, No. 1 Carlton-May well, located
about one mile southeast of the town of Jay, was plugged and
abandoned at a final depth of 6,580 feet. This well penetrated
the Tuscaloosa (Atkinson) section of Upper Cretaceous Woodbine
and Eagle Ford ages, which produces in the Pollard field, located
in Escambia County, Alabama, about 8 miles northwest of the
Carlton-May well.

Petroleum accumulation in the Pollard field is controlled by
closure against a northwest-southeast trending fault, downthrown
to the northeast. A paper by C. Victor Winter (1954, p. 121)
showed that production is from the Upper Tuscaloosa Miller Sand

to 5,905 feet. The Pollard field was discovered in 1952 by the
Humble Oil Company, and cumulative production to date is appro-
ximately 10 million barrels of 260 to 290 gravity oil.

The Young Drilling Company, No. 1 Carlton-May well is
structurally higher than nearby dry holes, on the Moye Sand, by
amounts ranging from 45 to 372 feet. Also, the interval in this
well between the top of the Eutaw Sand and the top of the Moye
Sand is from 45 to 133 feet thinner than it is in nearby wells.
The generally north dip between the Carlton-May well and the
Bray well (see table 2) is anomalous, since the regional dip is
to the south. The relatively high Carlton-May well found the Tus-
caloosa sands to be well-developed, though carrying salt water.

The Kirby and Sun Oil Company, No. 1 Jay Unit well, the
second Tuscaloosa test drilled in Santa Rosa County in 1964, was
located about 1.6 miles west southwest of the Carlton-May test.
It was drilled to a final depth of 6,524 feet by the George H.
Jett Drilling Company. On the top of the Moye Sand, this test
was 16 feet higher than was the Carlton-May well. Other than
this slight difference in structural elevation, there appears to be
little difference between the Tuscaloosa sections of the two
wells. No shows were reported from 11 sidewall core recoveries
taken from the Jay Unit well.

The Young Drilling Company, No. 1 Golden well, the third
and last Tuscaloosa test drilled in Santa Rosa County in 1964,
was located about one-half mile south of the Carlton-May well.
The Golden well was 115 feet higher in structural elevation on
top of the Moye Sand, than was the Carlton-May test, thus con-
tinuing the anomalous north dip indicated'by other wells in this
area. The electrical log showed that the Tuscaloosa sands in
the Golden well are well developed, but carry salt water. The
contractor for this test, which was plugged and abandoned at a
final depth of 6,539 feet, was the George H. Jett Drilling Com-
pany.

LAND

The latest summary of undeveloped lease holdings in Florida,
available to the Division of Geology, pertains to 1963, and is
from the International Oil and Gas Development Year Book (Review
of 1963), Part 1, page 60. This source, recapitulated below in
table 3, reveals that on December 31, 1963, eleven companies held
undeveloped mainland and offshore leases on 5,543,980 acres in
the State. The mainland acreage was held in 22 of Florida's 67
counties.

DADE COUNTY

On October 6, 1964, Mr. Wendell L. Roberts assigned his
10-year oil and gas lease on 24,830 acres of land in the Forty
Mile Bend area of northwestern Dade County to Mr. Barnett Serio,
of Natchez, Mississippi. The mineral rights on this acreage are
owned by the Trustees of the Internal Improvement Fund, by the
State Board of Education, and by Malcolm Wisehart. A description
of the acreage leased from the two State agencies follows:

All of the 24,830 acres consist of unsurveyed lands and is subject
to public easements (roads, levees, etc.).

The reserved interest on one-half of the mineral rights in
Section 16, Township 54 South, Range 35 East were leased from
Malcolm Wisehart. Drilling commenced on the Wisehart lease on
or before March 24, 1965, would satisfy the 18-month committ-
ment on this lease as well as on the wholly-owned State acreage.

The assignment of the lease to Mr. Serio perniits him to drill
a well anywhere upon the lease, and if this well is started by
March, 1965, to earn control over 160 acres. Full control of the
lease can be earned by drilling a second well within a period of
15 months after completion of the first well.

Subsequent to the above assignment, notification was received
from Dade County of regulations involving the drilling of oil and
gas wells within its jurisdiction. In view of this, the Trustees
of the Internal Improvement Fund and the State Board of Educa-
tion, on December 22, 1964, granted an extension for the drilling
of the first well beyond the March, 1965, date specified. This
extension is for a period of 120 days after the time all of the
drilling permits have been received.

On January 15, 1965, at a county zoning hearing in Miami,
the operator was granted a variance from the zoning regulations.
However, permission or approval to drill this well still must
be obtained from three additional agencies, which are: (1) The
Central and South Florida Flood Control District, (2) The Corps
of Engineers, and (3) the Florida Board of Conservation.

GENERAL VIEW OF THE SUBSURFACE GEOLOGY OF
NORTHWESTERN DADE COUNTY

The Forty Mile Bend area is underlain by a biostrome which
characterizes the Sunniland pay zone. One of the abandoned pro-
ducers in the field, the Gulf Oil Corporation et al, No. 1 State
Lease 340 well, contained 3 feet of well-developed biostrome
from 11,344 to 11,347 feet. This well produced a cumulative total
of 18,146 barrels of 200 gravity oil prior to its abandonment in
in September, 1955, because of mechanical difficulties. A well
located 2/2 miles to the northwest, the Commonwealth Oil Com-
pany, -et al, No. 1 State Lease 1055 test, contained 46 feet of
well-developed biostrome from 11,404 to 11,450 feet of depth.
A drill stem test of this interval, however, yielded 150 barrels
of salt water in 30 minutes.

The second of the two Forty Mile Bend field abandoned
producing wells, the Commonwealth Oil Company, et al, No. 1
Wisehart-State test, produced 14,742 barrels of 210 gravity oil
from a non-reefoid section consisting of 5 feet of dolomite. This
well was abandoned in July, 1955.

Northwestern Dade County is known to be underlain by geo-
physical anomalies.

THE PROPOSED SERIO WELL SITE

The proposed Serio well site is between the Commonwealth
Oil Company et al, No. 1 Wisehart-State well (located 3,600 feet
to the southwest), and the Commonwealth Oil Company et al, No.
1 State Lease 1055 test (located 7,700 feet to the northeast).
The Wisehart-State well was 67 feet higher in structural elevation
than was the State Lease 1055 test. The Wisehart-State well
contained promising oil shows in both the upper and lower Sunni-
land sections, neither of which was reefoid. This became the
discovery well for the Forty Mile Bend field on the basis of pro-
duction from 5 feet of dolomite in the upper Sunniland section.
In the down-dip State Lease 1055 test the upper Sunniland section
consisted of 46 feet of biostromal rock, flooded with salt water.
The proposed Serio well will test the inferred updip pinchout
of the upper Sunniland reefoid section which is present in the
No. 1 State Lease 1055 dry hole, but absent in the updip Wisehart-
State abandoned producer.

THE FELDA AREA AND ADJOINING PARTS OF SOUTH FLORIDA

As a result of the 1964 Sun Discovery, the major interest in
Florida at the present time is in the Felda area of Hendry and
Collier counties. Table 4, recapitulated from the International
Oil and Gas Development Year Book (Review of 1963), Part 1,
page 60, shows the summary of undeveloped lease holdings in
selected counties of south Florida in 1963. Interest in this area
was apparently concentrated in Hendry County even before the
Sun discovery.

Sun 691 1,140 20,201 3,838

The predominance of interest in Hendry County appears to
have been caused mainly by favorable though non-commercial
drill stem tests of the Sunniland "pay" zone in two wells drilled
in 1954 and 1959, which were, respectively: (1) Commonwealth
Oil Company, No. 3 Red Cattle Company and (2) Commonwealth
Oil Company and Gulf Coast Drilling and Exploration Company
No. 1 Red Cattle Company. These wells are shown on Cross
Sections A-A' and B-B' (figs. 4 and 5).

Leasing became active in the Felda area shortly after the
Sun Oil Company obtained a promising oil recovery from a drill
stem test of the Sunniland oil zone in their No. 1 Red Cattle Com-
pany well, which was plugged between June 17 and November 6,
1964. The Sun, No. 2 Red Cattle Company test, which commenced
drilling on June 25, 1964, proved to be the discovery well for the
Sunoco-Felda field.

Information on the leasing activities by companies which sent
lease men into the Felda area, and other parts of south Florida,
since the favorable drill stem test recovery in the Sun, No. 1
Red Cattle Company well can be summarized as follows:

INFORMATION CIRCULAR NO. 49

Lease Activity By Sun

By October 9, 1964, the date its No. 2 Red Cattle Company
discovery well was opened to production, Sun had increased its
leases in the Felda area to 108,516 acres from the approximately
20,000 acres held when they commenced drilling here.

Sun also leased, in the latter part of 1964, the mineral rights
on two leases totaling 10,581.6 acres east of Estero, in Lee
County, from Alico Land and Development Company of La Belle
for $1.00 an acre per year. One of these leases covers 5,435.8
acres, and the other covers 5,145.8 acres. The leases give Sun
the rights to oil, gas, sulphur and salt, and to any minerals found
more than 150 feet below the surface. Alico reserves the right to
mine any sedimentary minerals such as sand, clay, limestone,
marl or phosphate found within 150 feet of the surface, providing
the mining operations can be carried on without interfering with
drilling by Sun.

In addition, Sun leased one-half interest in 3,240 acres of
State land in the Felda area of Hendry and Collier counties. A
total of 3,200 acres of this land is owned by the State Board of
Education and consists of five sections, located in Townships
45 and 46 South and Ranges 28, 29 and 30 East. The remaining
40 acres is owned by the Internal Improvement Fund. All of this
State acreage is distributed around a perimeter about 1 to 5 miles
distant from production found to date in the field. Details on this
leasing are presented in appendix 3.

Lease Activity By Humble

In the latter part of 1964, Humble acquired leases on about
100,000 acres of the Consolidated Naval Stores land in Lee Coun-
ty.

Lease Activity By The Alvin S. Moody-J. L. (Pat) McCord Group

This group holds an option on the oil and gas rights to 770
acres located within 2% miles south of the discovery well for the
Sunoco-Felda field.

A tabulation of available scout information on geophysics on
the Florida mainland in 1964 is, presented in table 6, which shows
that approximately 34 1/3 crew weeks of seismic work was done
in 1964, mostly in south Florida.

Florida Offshore

There was more geophysical activity offshore from the coasts
of Florida in 1964 than in any previous year. Permitted geophysi-
cal activity for 1963 and 1964 is presented in appendix 4, which
shows that geophysical work has been scheduled to cover almost
the entire offshore west coast of Florida, ranging out. to water
depths of 600 feet.

included in the present report as appendix 5.

2. On December 15, 1964, the State Board of Conservation,
following a public hearing pursuant to an application made by
the Sun Oil Company, issued Order No. 1, appendix 6, providing,
temporarily, for 160-acre spacing for oil wells. This spacing
provision is not final but is subject to review within a period
of 12 months.

The guide lines followed by the State in formulating Order No.
1 were: (1) to more effectively conserve its oil and gas resources,
(2) to protect correlative rights, and (3) to encourage further de-
velopment.

GEOPHYSICS

Florida Mainland

A tabulation of available scout information on geophysics on
the Florida mainland in 1964 is, presented in table 6, which shows
that approximately 34 1/3 crew weeks of seismic work was done
in 1964, mostly in south Florida.

Florida Offshore

There was more geophysical activity offshore from the coasts
of Florida in 1964 than in any previous year. Permitted geophysi-
cal activity for 1963 and 1964 is presented in appendix 4, which
shows that geophysical work has been scheduled to cover almost
the entire offshore west coast of Florida, ranging out. to water
depths of 600 feet.

In the last month of 1964 the Sunniland field produced about
2,250 BOPD (barrels of oil per day) from 15 pumping wells. This
more than doubles the average daily yield from the field in 1961,
and. reflects the. opening to production, beginning in 1962, of new

tion previously was obtained.

been prepared by the State Board of Conservation. This has been
included in the present report as appendix 5.

2. On December 15, 1964, the State Board of Conservation,
following a public hearing pursuant to an application made by
the Sun Oil Company, issued Order No. 1, appendix 6, providing,
temporarily, for 160-acre spacing for oil wells. This spacing
provision is not final but is subject to review within a period
of 12 months.

The guide lines followed by the State in formulating Order No.
1 were: (1) to more effectively conserve its oil and gas resources,
(2) to protect correlative rights, and (3) to encourage further de-
velopment.

SUNNILAND FIELD

Production

Monthly oil production from the Sunniland Field in 1964 is
shown in table 7. A well location map of the field is provided in
figure 2. The field is operated by the Humble Oil and Refining
Company.

FLORIDA GEOLOGICAL SURVEY

The steady increase in yearly production from the Sunniland
field, 1961-1964 inclusive, with wells opened to deeper zones
which caused this increase, is shown in table 8. The locations
of the wells opened to the deeper zones, with the chronological
sequence of the well completions, is shown in figure 2.

In addition to completing three new producing wells in 1964
(table 8 and fig. 2), the operator recompleted the No. 18 Gulf
Coast Realties Corporation well, which was originally completed
in 1962 through perforations in the "D" zone at 11,585-11,589
feet as a producer of 198.5 BOPD and about 20 barrels of water
per day.

Upon recompletion in 1964 the "D" zone was cemented off and
perforations were opened in an upper zone at 11,559-11,567 feet.
In a test conducted June 30, 1964, this zone produced 495 BOPD
and 21 barrels of water. However, during the month of October,
1964, the production from the upper zone averaged 282 BOPD
and 145 barrels of water.

The well sheets of appendix 1 provide further information on
1964 operations in the Sunniland field, including the drilling of

INFORMATION CIRCULAR NO. 49

the No. 20 Gulf Coast Realties Corporation test, the only dry hole
for the field during the year.

The Sunniland crude oil is black and medium in weight (19-
260 A.P.I. gravity). It is associated with little gas (gas-oil ratios
are about 100 to 1). This crude oil is suitable principally for fuel
products.

Price Of The Crude Oil At The Well Head

In 1964, Humble's Sunniland crude oil sold for an average
price of $2.0087 per barrel at the well head. Corresponding figures
for the last 6 years are shown in table 9.

Table 9. Average price at the well head of Humble's
oil. 1959-1964. inclusive.

1961 2.3921

1962 2.0938

1963 1.9880

1964 2.0087

The State of Florida receives a 5 percent severance tax on
the gross value of the oil at the well head (Florida Statutes Chap-
ter 211.02, instituted in 1945 and revised in 1947).

Distribution

In 1964, as in previous years, Humble's Sunniland crude oil
was trucked from the field to Port Everglades just south of Fort
Lauderdale, from which tankers transported it to the refinery at
Bay Way, New Jersey.

The Sunniland Pipe Line Company will complete a 4-inch pipe
line from the Sunniland field to the Belcher Oil Company Terminal
at Port Everglades in the near future; and effective March 1,1964,

FLORIDA GEOLOGICAL SURVEY

this company is authorized to transport Humble's crude oil through
its line. It is also understood that construction of a 6-inch line is
being considered, to permit the company to handle oil from both
the Sunniland and Sunoco-Felda Fields.

SUNOCO-FELDA FIELD

A well location and land map of the Sunoco-Felda field is
provided in figure 3. This map has been brought up-to-date by
revisions to December 1, 1965.

Production from this field began when the Sun Oil Company
No. 2, Red Cattle Company discovery well flowed 111 BOPD from
the open hole at 11,472-11,485 feet on the official production test.

The interval from which this production was obtained has
been designated theRoberts pool (zone) in State Board of Con-
servation Order No. 1, which used the Sun Oil Company, No. 1
Red Cattle Company well, a small producer, to indicate the zone.
Data on this well, including the cores and the electrical log, are
indexed as No. W-6644 in the files of the Florida Geological Sur-
vey in Tallahassee.

In the Commonwealth Oil Company, No. 3 Red Cattle Company
well, shown in figure 4, which was plugged and abandoned despite
a favorable drill stem test recovery from the zone, and which is
located 2 miles northeast of present production in the field, the
Roberts zone is 17 feet thick. It was reached at a depth of 11,483
feet, which occurs 67 feet below the top of the Sunniland Lime-
stone as defined by Paul L. Applin (1960, B 209); and it imme-
diately underlies a vertical permeability barrier consisting of
about 6 feet of hard to medium hard calcilutite (fine grained lime-
stone). The lower limit of the zone is picked at 11,500 feet, which
is the top of a relatively impermeable and resistive rock, and
which in this well appears to occur at the approximate oil-water
contact. The lithology of the Roberts zone in the Felda area is
calcarenite (medium grained limestone) which is brown, soft,
porous, miliolitic and partially dolomitized with incipient crys-
tallization; cores of this section in the Sunoco-Felda field are
saturated with heavy brown oil. It appears that the Roberts zone
of the Sunoco-Felda field is correlative with the lowest produc-
tive interval in the Sunniland field, referred to as the "D" zone
by the Humble Oil and Refining Company.

this company is authorized to transport Humble's crude oil through
its line. It is also understood that construction of a 6-inch line is
being considered, to permit the company to handle oil from both
the Sunniland and Sunoco-Felda Fields.

SUNOCO-FELDA FIELD

A well location and land map of the Sunoco-Felda field is
provided in figure 3. This map has been brought up-to-date by
revisions to December 1, 1965.

Production from this field began when the Sun Oil Company
No. 2, Red Cattle Company discovery well flowed 111 BOPD from
the open hole at 11,472-11,485 feet on the official production test.

The interval from which this production was obtained has
been designated theRoberts pool (zone) in State Board of Con-
servation Order No. 1, which used the Sun Oil Company, No. 1
Red Cattle Company well, a small producer, to indicate the zone.
Data on this well, including the cores and the electrical log, are
indexed as No. W-6644 in the files of the Florida Geological Sur-

In the Commonwealth Oil Company, No. 3 Red Cattle Company
well, shown in figure 4, which was plugged and abandoned despite
a favorable drill stem test recovery from the zone, and which is
located 2 miles northeast of present production in the field, the
Roberts zone is 17 feet thick. It was reached at a depth of 11,483
feet, which occurs 67 feet below the top of the Sunniland Lime-
stone as defined by Paul L. Applin (1960, B 209); and it imme-
diately underlies a vertical permeability barrier consisting of
about 6 feet of hard to medium hard calcilutite (fine grained lime-

On November 23, 1964, the discovery well pumped, through a
28/64-inch choke, 427 BOPD, with 11 barrels of B.S. and W.
Additional information on this well is presented in the well sheets
(app. 1). As of the end of the year, drilling was completed on
the confirmation test, the Sun Oil Company, No. 1-A, The Collier
Company well (fig. 3, and the well sheets of app. 1). On a pro-
duction test conducted February 2, 1965, this well pumped from
the open hole at 11,488-11,495 feet, with no choke, 127 BOPD with
226 barrels of water.

The yield of the Sunoco-Felda field in 1964, by months, with
the wells which contributed to this production, is shown on table
10.

Discussion of Geologic Cross Sections and Maps

FELDA AREA CROSS SECTIONS

The lithology shown on cross sections A-A' and B-B', figures
4 and 5, was described from 1-foot cores. The lithologic symbols
used in the sections were designed to facilitate correlation with
the electrical log. Thus, the wider the lithology symbol, the
harder the rock. This is an aid to correlating the resistivity curve
for a given well with samples or cores in that well. Where wells
are sufficiently close together, also, this procedure is useful in
correlating the lithology of one well with that of another.

Calcarenite (medium grained limestone) and calcilutite (fine
grained limestone) are defined at length in appendix 7. Both of
these rock types are represented by standard limestone symbols
(blocks), but for calcarenite the symbol is slightly larger, to
indicate the larger size of the constituent particles. Generally,
on the wells depicted in the sections, there is an increase in the
Spontaneous Potential opposite calcarenite, suggesting that the
relatively large grain size of this rock makes it more permeable
than calcilutite.

Some facts that are revealed by the cross sections A-A' and
B-B', with comments, are as follows:

1- The vertical permeability barrier overlying the Roberts
zone which produces in the Sunoco-Felda field consists of hard
to moderately-hard calcilutite and shaly calcilutite about 6 to 10
feet thick. The cap rock overlying the upper producing interval
in the Sunniland field, on the other hand, is an anhydrite ranging
from 30 to 40 feet in thickness. Drill stem test recoveries reveal
that in the Felda area the vertical permeability barrier is overlain
by salt water and underlain by oil.

It is possible that some of the non-productive wells in the
Sunoco-Felda area are located where this vertical permeability
barrier has been inadequate to prevent the upward escape of oil
accumulation. Possibly indicating such escape is the oil staining
found in the permeability barrier of two wells shown on cross
A-A'. These tests are the Commonwealth Oil Company, :No. 3
Red Cattle Company well, and the Commonwealth and Gulf Coast
Drilling and Exploration Company, No. 1 Red Cattle Company

INFORMATION CIRCULAR NO. 49

well. In the Sunniland field, however, even thinner hard limestone
layers 3 -to 5 feet in thickness are sufficient to separate the oil
in reservoirs A,B,C and D.

2. The reservoir rock of the Roberts zone (defined in this
report under "Production, Sunoco-Felda field") ranges from 12
to 23 feet in thickness in the wells of the cross sections. Of
the wells shown, the one which is nearest to production in the
Sunoco-Felda field is the Commonwealth Oil Company, No. 3
Red Cattle Company test, located 2% miles northwest of the Sun
Oil Company, No. 2 Red Cattle Company discovery well. The
drill stem test recovery from the Roberts zone in this Common-
wealth well (1,090 feet of oil in 7% hours) was the most favorable
of any taken in the wells depicted in the cross sections. The
core of the interval tested reveals that in this well the zone
consists of calcarenite which is brown, soft, porous, miliolitic
and partially dolomitized with incipient crystallization; the core
is saturated with heavy brown oil.

Strike section A-A' shows that 1% miles northwest of the
Commonwealth Oil Company well the calcarenite of the Roberts
zone becomes slightly harder, though it is still porous. The zone
was oil saturated, but oil recovery from the drill stem test was
low (5 feet of oil in 1% hours). About 20% miles to the southeast
the calcarenite of this zone is soft and porous as it is in the
Commonwealth Oil Company. No. 3 Red Cattle Company well,
but it lacks oil staining and is flooded with salt water.

Dip section B1 B shows that down-dip to the southwest the
Roberts zone consists of hard but porous limestone without oil
staining, and it is probably flooded with salt water. Up-dip to
the northeast is the Humble Oil and Refining Company, No. 1
Consolidated Naval Stores, Hole No. 2 well, which is located
about 4 miles north of the discovery well for the Sunoco-Felda
field, and which is structurally the highest well in the Felda
area. In this Humble well the zone is made up of calcarenite which
is moderately soft and dense, and which has only slight porosity.
The only oil show present consists of staining and a slight oil
cut from 2 feet of a core at 11,408-11,410 feet. It is reported that
at the time the core at this approximate interval was originally
described it contained "bleeding oil"; however, porosity is no
better than that described above for the entire zone. A drill stem
test from 11,414-11,426 feet recovered salt water with no oil.

FLORIDA GEOLOGICAL SURVEY

3. The oil-water contact, as revealed by staining in cores and
by electrical log resistivities, was determined primarily for the
two wells shown on the cross sections which had oil recoveries
from drill stem tests.

It is concluded from the above facts and comments, that where
commercial oil accumulation in the Roberts zone of the wells
shown on cross sections A-A' and B-B' is lacking, one or more)
of the causes may be: (1) inadequate capping material, (2) flood-
ing of the zone with salt water (in down-dip wells)" and (3) poor
to relatively poor permeability (north of the Sunoco-Felda field).

The two plugged and abandoned wells in the Felda area which
yielded oil and a preponderance of salt water on drill stem tests
of the Sunniland Limestone, shown in figures 4 and 5 (cross sec-
tions A-A' and B-B'), are more promising than was initially appa-
rent. This is concluded since both wells tested an interval that
included a water zone, the Roberts oil-bearing zone and the per-
meability barrier that separated them, as shown in table 11. It
is probable that if the Roberts zone only had been tested, oil
and salt water percentages would have been much more encou-
raging, and possibly the rate of oil recovery would have been
greater.

In the Sunniland Limestone, about 120 to 130 feet below the
base of the Roberts zone and 30 feet above the top of the Punta
Gorda Anhydrite, as described by the Applins (1965, p. 39), oil
shows are present in hard calcareous rock in the Humble Oil and
Refining Company, No. 1 Consolidated Naval Stores well, of
Lee County, and in the same operator's No. 1 Consolidated Naval
Stores test in Hendry County. During a drill stem test the Lee
County well recovered 2,130 feet of gas and 90 feet of oil (fig.
5). It is interesting that in the wells, most of the less indurated
rock of the Sunniland Limestone lacks shows. Quite often in
south Florida shows are found in tight rock but not in porous
rock. It is possible that in the Felda area, in Early Cretaceous
sections, this circumstance may be explained by the flushing
of oil zones by circulation of either salt or fresh water.

MESOZOIC CROSS SECTIONS OF NORTHWESTERN FLORIDA

The Citronelle oil field of Mobile County, Alabama is located
33 miles west-northwest of the Florida-Alabama boundary. The
1961 production from the Rodessa-Pine Island-Sligo section of
Lower Cretaceous (Trinity) Age in this field was 5,872,403 bar-
rels of high gravity oil (averaging 40 to 45 degrees A.P.I.) from
290 pumping wells. Cumulative production from discovery of the
field in October, 1955, to January 1, 1962, was 26,945,022 barrels
of oil (Oil and Gas Year Book of 1962, Part 2, p. 11). The depth
from which production was obtained ranged in the discovery well,
the Zack Brooks, No. 1 Donovan test, from 10,870 to 11,414 feet
(Frascogna, 1957, p. 38). This depth range is typical for Citro-
nelle field wells.

In Mississippi 29 oil fields and two gas fields produce from
the Rodessa-Sligo sequence, according to a summary (1962) by
Henry N. Tolar, Consulting Geologist.

Rock units which make up the Rodessa-Pine Island-Sligo
sequence in the area of the Citronelle field are shown in figure 8,
which is a stratigraphic comparison chart extracted from an un-
published thesis by Henry J. McCoy (1958, p. 8).

Cross sections using 12 wells extending from Citronelle field
to a test offshore from Franklin County, Florida are given in
figures 9, 10, and 11. Tops shown on these sections were based
on sample and electrical log study by several workers in this
area, and by the writer, who assumes responsibility for all of
the tops.

Well control is inadequate to reveal the strike of Mesozoic
formations in southern Alabama and northwestern Florida. It is
believed, however, that the east-west cross sectional line A-A'
approximately parallels the northern boundary of the basin in
which Mesozoic sediments were deposited. The electrical log
cross sections (figs. 9, 10 and 11) reveal:

1. The depths, and possible depths, at which the Rodessa-
SPine Island-Sligo section may be reached in northwestern Florida.

2. The Rodessa-Pine Island-Sligo sediments in the three
deep tests in Escambia and Santa Rosa counties, Florida are

quite similar to those in the Citronelle field. The Ferry Lake
Anhydrite is common to both areas, and serves as a good marker
in electrical log correlations. The presence of this unit, as well
as other anhydrites, proves the existence of an evaporite basin.

3. Mesozoic formations are higher, beginning with the Pan
American, No. 1 Sealy test in Walton County, Florida, on the
east end of cross section A-A' than they are on the west end.
For example, the structural elevation of the Mooringsport Forma-
tion is 2,967 feet higher in the Gulf Coast Drilling and Exploration
Company, No. 1 U.S.A. well, in Liberty County, Florida than it
is in the Citronelle field. Also the predominantly red shaly cha-
racter of the Mesozoic sediments in the eastward wells of cross
section A-A' indicates that they are the updip equivalents of the
more calcareous sediments of Mesozoic age to the west. For these
reasons correlations of the Mesozoic section in wells to the east
with the Citronelle field section is difficult. Also, the section
in the eastward wells appears much less promising than is that
nearer to the Citronelle field because of the large increase in
the percentage of red shares to the east.

It may be inferred that the eastward continuation of the Meso-
zoic horizons which underlie the Citronelle field lies south of
the eastward extension of cross sectional line A-A' in a trough
approximately outlined on a structure map by Antoine and Hard-
ing (1965, p. 169) of the pre-Cretaceous basement based on seis-
mic refractions, as shown in figure 12. It shows that the axis of
the trough lies offshore and parallels the northwestern coast of
Florida; this trough is about 35 miles wide at the 15,000-foot
contour level; and it is filled with sediments (of probable Mesozoic
and Cenozoic ages) with a thickness in excess of about 15,000
feet.

Virginia-Carolina Chemical Company. A number of oil companies,
also, have been actively exploring for new deposits of phosphate,
primarily in the northeastern and northern parts of the State, espe-
cially in the area of Hamilton, Columbia, Baker, Union, Bradford,
Alachua, Suwannee and Madison counties. These companies in-
clude Occidental Oil Company, Gulf Oil Corporation, Tenneco
Oil Company, Shell Oil Company, Sinclair Oil and Gas Company,
Esso and Kerr-McGee Oil Company. It is reported that in 1965,
the Occidental Oil Company will construct a 10 million dollar
phosphate plant in southeastern Hamilton County.

The primary reasons for the trend of investment by oil com-
panies in the phosphate industry are:

1. Nitrogen and phosphate are two of the basic ingredients in
fertilizer (with the third ingredient being potash). Large oil com-
panies have almost unlimited supplies of nitrogen as a by-product
of their production of natural gas. They are acquiring phosphate
to bring these two important ingredients under one management.

2. One of the largest customers of the oil companies is the
American farmer, an established buyer of fuel, gas and pesticides.
It is anticipated that using this established market as a common
channel for the integrated fertilizer products will be an advantage
to the expanding fertilizer industry.

3. It is estimated that the annual increase in fertilizer demand
will be 10 percent in the United States alone, and that world fer-
tilizer demand will double by 1970. This anticipated growth of
the fertilizer market is attractive to oil companies seeking in-
vestment opportunities.

in the eastward wells appears much less promising than is that
nearer to the Citronelle field because of the large increase in
the percentage of red shares to the east.

It may be inferred that the eastward continuation of the Meso-
zoic horizons which underlie the Citronelle field lies south of
the eastward extension of cross sectional line A-A' in a trough
approximately outlined on a structure map by Antoine and Hard-
ing (1965, p. 169) of the pre-Cretaceous basement based on seis-
mic refractions, as shown in figure 12. It shows that the axis of
the trough lies offshore and parallels the northwestern coast of
Florida; this trough is about 35 miles wide at the 15,000-foot
contour level; and it is filled with sediments (of probable Mesozoic
and Cenozoic ages) with a thickness in excess of about 15,000
feet.

INVESTMENTS BY OIL COMPANIES IN THE
PHOSPHATE INDUSTRY OF FLORIDA

Recently a number of oil companies have invested in phos-
phate companies of Polk and Hillsborough counties. Cities Service
Oil Company has taken over the Tennessee Corporation and its
subsidiary, U.S. Phosphoric Products Division; Continental Oil
Company has merged with the American Agricultural Chemical
Company; and Socony-Mobil Oil Company has merged with the

(5) The operator made successful recoveries on three fishing jobs beginning at about 2,700 feet where a caving
boulder zone was drilled. Drilling operations with an 11-inch bit were continued to a depth of 4, 550 feet,
which was to be the casing seat for intermediate (9 5/B-inch) casing. On the second "wiping" pass made
into the hole to assure clearance for the casing, the bit would not go below the depth of about 2, 700 feet,
at which.the boulder zone had been encountered in drilling operations.
At this point the operator began reaming the hole with an 11-inch bit. By the time the operator had reamed
to 3, 550'feet, however, the drill bit had strayed 7 j degrees off its course. Since the acceptable limit to
deviation is 21 degrees, the operator decided to abandon the hole.

*This step-out well is 1 miles SE of the Red Cattle No. 2 discovery Well.

COLLIER COUNTY

(6) Because of the relative scarcity of shallow water to be used for drilling purposes in the area of this well, it
was decided to convert this hole to use as an (artesian) water well. Casing (13 3/8-inch) was perforated at
752-762 feet, 810-816 feet, 836-846 feet and 902-912 feet.
After the well has served its purpose as a water well for drilling operations, the operator will cement off the
pe:forations and otherwise complete plugging the hole as required to protect fresh water resources.

HISTORIC AND ECONOMIC ASPECTS CONNECTED WITH
SUN'S OIL ACTIVITIES IN FLORIDA

By
Mr. Tom F. Hill

The Sun Oil Company has explored in Florida since 1935,
and since that time has acquired 4,716 oil and gas leases on
almost 4,000,000 acres of land. The peak amount of acreage,
2,374,062 acres, was held in 1949.

Sun has drilled 34 dry holes in Florida, and has supported
through some form of contribution 38 additional wells. Footage
drilled in the 72 wells in which Sun has been interested has a-
mounted to 462,471 feet. The activities of the company were con-
centrated in the Florida Panhandle, and around the Peninsular
Arch. The first well undertaken by the company in south Florida
was their No. 1 Red Cattle Company well drilled in the early part
of 1964; this well tested promising, but non-commercial oil shows,
and led the company to drill the No. 2 Red Cattle Company dis-
covery well.

Money spent by the Sun Oil Company in Florida prior to the
discovery of the Sunoco-Felda field was:

Payments to landowners $7,447,410
Lease bonuses 1,734,163
Lease rentals 5,713,247
Geophysics (mainly seismic) 1,026,691
Core drilling 218,205
Dry hole contributions 52,456
Test well drilling in which Sun
was the operator 1,647,975

TOTAL $10,392,737

The Sun No. 2 Red Cattle Company Well

The results of the favorable drill stem test which indicated
the promise of this well, were:

$415,504

Additional cost elements involved in developing the No. 2 Red
Cattle Company well to its full potential may run these costs up
an additional $100,000.

A tabulation showing the net value per barrel of this crude
was reported to be:

Gross value at the well head $2.54
Less: State severance tax 0.13
Trucking, to Port Everglades 0.42
Terminal space at the port 0.05
Royalty to the landowner 0.24
Overhead 0.03
Direct operating cost 0.15
Net value if produced natural 1.52
Less: pumping cost? 0.10
Net value if produced by pump $1.42

The landowners return per barrel of $0.24 is determined by mul-
tiplying his 1/8 royalty times a base figure consisting of: Gross
value at the well head, less state severance tax, less trucking
cost to Port Everglades.

Transportation of the Sunoco Crude

Mr. Hill briefly mentioned that Sun might transport the crude
oil to Port Everglades either by barge over the Okeechobee Water-
way, or entirely by truck, or by truck to the Sunniland field and
from there to Port Everglades by a pipeline now being constructed
to handle the crude produced in the Sunniland field. Mr. Hill also
mentioned that Sun may build a pipeline either to Port Everglades,
or to the Sunniland field. Daily production figures necessary to
justify pipeline construction, according to Mr. Hill, are:

Land

Early this year Sun held 23,527 acres of land. After the ter-
mination of their No. 1 Red Cattle well an additional 2000 acres
were acquired to increase Sun's total holdings to 25,527 acres.
After the favorable DST from the No. 2 Red Cattle well, the com-
pany intensified leasing activity sharply, and now holds 108,516
acres in the Felda area under oil and gas lease.

REMARKS: (1) General area: This survey was run within 650 feet of the California Company Coastal Petroleum Company
No. 3 Florida State Lease 224-B well, located offshore from Dunedin, Pinellas County.

(2) Miscellaneous: The velocity survey of above described No. 3 State Lease 224-B well required about 10 hours
to complete.
The name of the explosive used in the charge set off in the water is Nitroman. This is a mixture of nitrogen -
and a petroleum product similar to diesel oil. It is set off by a primer made of a higher velocity explosive;
the Nitroman itself is of relatively low velocity. It can be exploded with a primer only, and consequently it
is not classified as an explosive insofar as its transportation is concerned. The charges of Nitroman used
varied from 1 to 50 pounds, with the smaller charges being used near surface and the larger charges at greater
depth. The maximum charge used.(50 pounds) produced a geyser of water about 7 to 10 feet in diameter.

Survey procedure: Every thousand feet going into the hole being checked, and every 500 feet coming out of
the hole, a shot is fired. The shots are suspended about 10 feet below the water surface from floating
balloons which are at an electronically-determined distance of about 650 feet from the test hole. Vertical
depths to interfaces are determined from the expired tithe between the explosion and its pick-up by the 0
recording sonde in the test hole.

Purpose of survey: This survey is made to a) correct the sonic log, and b) provide velocity data to be
used in conjunction with seismic times.

(2) Miscellaneous: The energy source for the gas gun echo sounder is a gas reactor which is a chamber of
pipe that is lowered about 15 feet below the water surface, A mixture of propane and air is fired in the
chamber about every 6 seconds as the boat moves at a speed of approximately 4 miles per hour. The
final record is a composite of several shots.
The energy from the combustion produces a low level, low frequency impulse which does no harm to
water bottoms or to marine life.

to last about 1 month)
Weeks worked in 1964: 2 weeks

(1) General area: The lines were at widely spaced intervals along the entire Gulf Coast of Florida.

(2) Number of boats: 3

(3) Distance between shots: some 440 feet; some 880 feet.

(4) Miscellaneous: Three vessels were used in this operation. The lead instrument vessel towed an underwater
seismograph cable 10,700 feet long. According to preliminary plans, about 2 days were to be spent on each
line.to be run.
Because of the great distances involved in refraction shooting (10 miles or more), very large charges were
required for the refraction part of the program.

REMARKS: (1) General area: In the Atlantic Ocean northward from latitude 29' I51 north (slightly north of Daytona Beach,
Florida), to the Florida-Georgia state line, (The completed program will include offshore areas northward
beyond Florida's boundary to the Virginia-North Carolina state line). This survey is to extend from the
15-foot contour line to the 600-foot contour line,

(2) Miscellaneous: a) This operation is a resumption of echo sounding activities started by Mobil in the latter
part of 1963 in the Florida Keys under Permit 3.
b) A description of the basic principles of operation of the gas gun echo sounder is described under Permit 2
