PRODUCTION
Sunoco-Felda Field
The Sunoco-Felda oil field, figure 1, the newer of Florida's two currently
producing fields, was opened officially to production by the Sun Oil Company
on October 9, 1964. It is located in southern Florida mainly in Hendry County,
with the southern edge extending into Collier County. As of December 31, 1968
this field contained 28 pumping wells; and the limits of the field to the north,
south and east had been defined by 9 dry peripheral field wells, and 3 outpost
wells.
Yields from the better wells in the field range from about 200 to 320 BOPD;
the gravity of the oil is about 24.5 degrees API. Production from the
Sunoco-Felda field in 1968 decreased 9 percent below that of 1967. Table 1
shows production by months for 1967 and 1968, and cumulative production as
of December 31, of each of the respective years.
SUNOCO-FELDA FIELD
The Sunoco-Felda field produces on pump from the Roberts zone, which
occurs about 65 feet below the top of the Sunniland Limestone (defined by Paul
L. Applin, 1960, p. 209) of Lower Cretaceous Trinity Age. The Roberts zone
consists of microfossiliferous (miliolitic) limestone reached at depths ranging
from about 11,462 feet to about 11,495 feet. It appears that a permeability trap
is responsible for oil accumulation in the field. The producing interval in
up-gradient wells to the north is tight and yields a large percentage of salt water.
In 1968 field drilling consisted of 34,599 feet penetrated in two producing
wells and a dry hole, table 2, all located in the western part of the Sunoco-Felda
area; data sheets on these wells are included in appendix 1. The two producers,
which on initial production pumping tests yielded a combined total of 187
BOPD (barrels of oil per day) with 249 barrels of water,. are offsets to a
commercially marginal step-out located 3% miles west of the main part of the
field and completed in 1966. The offset dry hole drilled in 1968 in this western
area defines the limit of the reservoir to the north. At the present time the Sun
Oil Company has a permit to drill yet another offset, to the south, to production
in this area.- This well will be the Sun, No. 28-3 Lee-Cypress "A-l"; it will be
located on acreage under lease to the Humble Oil and Refining Company, and
drilling of the test should commence in the first part of 1969.

It may be proven that there is an oil-permeability barrier between the original
Sunoco-Felda field and the producing wells in the western part of the
Sunoco-Felda area. Figure 2, which is a structure map contoured on top of the
Sunniland Limestone marker of the Sunoco-Felda area, shows two plugged and
abandoned wells which are structurally high, and which are located between the
Sunoco-Felda field proper and the producing wells to the west. These
intervening wells produced large quantities of salt water on DSTs (drill stem
Tests) of the Roberts "pay" zone; the results were:

In the Sun, No. 26-1 Lee-Cypress well the "pay" zone consists of soft
limestone which appears to have the porosity characteristics of a classic chalk.
The subject section, also, is fairly soft in the Commonwealth and Gulf Coast
Driving Company, No. 1 Red Cattle Company well. The porosity of chalk is
extremely good, but the pore spaces are minute. Such rocks may contain water;
and it is possible that the original Sunoco-Felda field, and the western part of
the Sunoco-Felda area, have a common water drive. But in most cases chalk acts
as a barrier to oil migration.

SUNNILAND FIELD

The Sunniland oil field (fig. 1) discovered in 1943 and operated by the
Humble Oil and Refining Company, is located in Collier County about 18 miles
south of the Sunoco-Felda field.
Production from the Sunniland field in 1968 decreased 0.67 percent below
that of 1967. Table 3 shows production by months for 1967 and 1968, and
cumulative production for each of the respective years.

At this time it is thought that 35 million barrels of oil probably is a reasonable
figure for the initially recoverable reserves of the field. The oil has a gravity of
19 to 26 degrees API (American Petroleum Institute).
Production in the Sunniland field is obtained from calcareous rock containing
disoriented macrofossils (rudistids), which is reached at a depth of about 11,500
feet. Productive zones begin at the top of the Sunniland Limestone and extend
to a point about 75 feet lower in the section. The lowermost of the five zones
has a bottom-water drive, and is correlative with the productive Roberts zone of
the Sunoco-Felda field (unpublished cross-sections by Woodson R. Oglesby of
the Division of Geology).

INFORMATION CIRCULAR NO. 65

As shown in table 2, Humble, No. 25 Gulf Coast Realties Corporation well,
which reached a total depth of 11,705 feet, was the only Sunniland field well
drilled in 1968, well data on this test is included in appendix 1. The initial
pumping production test on this marginally productive well, figure 3, completed
in the upper "C" zone of the Sunniland Limestone, was 62 BOPD in 368 barrels
of fluid. Perhaps the high percentage of salt water in this structurally high edge
well located on the north flank of the field is the result of a tilted oil-water
contact due to production from the field over many years.
On December 17, 1968, the Humble, No. 26 Gulf Coast Realties Corporation
well was permitted. This Sunniland Limestone test, which will be drilled in the
early part of 1969, will be located on the southern flank of the field, and about
1,400 feet south of the structurally-high No. 21 well (fig.3), which on IP (initial
production) test of the "D" zone of the Sunniland Limestone pumped 376
BOPD, with 35 percent salt water, The newly-permitted No. 26 test may prove
to be about on strike with the following field wells which are relatively low in
structural elevation:

Humble well Distance and Direction
(date of completion) from No. 26 well Comment
No. 8 1,700 feet southeast Flowing IP was 527 BOPD
(1946) with 0.4% salt water.
Abandoned in 1966 because
of technical difficulties.
No. 24 3,200 feet northwest IP on pump was 464 BOPD
(1965) with 8% salt water.
If the No. 26 test proves to be a good producer, it seems that the No. 9 well,
abandoned as a dry hole in 1947, deserves further consideration. Figure 3, shows
that the top of the Sunniland Limestone occurs at a sub-sea datum of 11,535
feet, which is 15 feet lower than the No. 24 well which is located about 1,500
feet to the north. Two zones were drill stem tested in the No. 9 well, with the
following results:
First DST (zone "A"). Following acidation, several favorable DST's were
recorded from this zone. The results of the most conservative DST were:
Interval: 11,566 11,570 feet

INFORMATION CIRCULAR NO. 65 9
Comment: The inflow into the drill pipe is at a rate of about 380 BOPD.
However, it will be noted that there is a considerable difference between the
shut-in pressure (4,400 psi), and the flowing pressure (1,500 psi); it appears that
relatively poor permeability causes the formation to be rather easily "bled-off."
There is more disparity between the subject pressures in zone "A" in the No. 9
well than there is in producing wells in the field.
Second DST. The total depth of the electrical log is 11,590 feet, which is
shallower than the second DST; therefore log correlation cannot be used to
determine the Sunniland "pay" tested. On the basis of interval, however, it
appears the tested interval is the lower part of zone "C1 ", or the upper part of
zone "C2". The tested interval was not acidized.

EXPLORATION
EXPLORATORY DRILLING
As recapitulated in table 4, a footage of 79,474 feet was drilled in 1968 in 9
exploratory wells in Florida (fig. I and appendix 1). Of the total, there was
penetration of 56,316 feet in 7 rank exploratory wells, and 23,158 feet in 2 field
outpost wells. One of the outpost wells, the Sun, No. 26-1 Lee-Cypress test, is
discussed under the "Production, Sunoco-Felda field" heading of this report.
The electric-lithologic log, and well data, of the other outpost well, the R-K
Petroleum Company, No. 2 1939-1939 S test, are depicted in the cross sections
and maps of the Forty Mile Bend area, which are presented in the next part of
the report.
FORTY MILE BEND AREA
Two wells of the abandoned Forty Mile Bend field produced 32,888 barrels of
oil in 17 months in 1954 and 1955. The Lake Trafford-Punta Gorda intervals in
these wells, and in 10 additional tests in the Forty Mile Bend area, all located as
shown on the index map of figure 4, are depicted in stratigraphic cross sections
A-B, B-C, C-D and D-E, figures 5, 6, 7 and 8. The primary purpose of these
sections is to show the top of the Sunniland Limestone, and to integrate
lithologic, electrical log, and drill stem test and production data for the included
wells.
The carbonate lithology shown in the cross sections of this report are depicted
as calcarenite (medium grained limestone) or calcilutite (fine grained limestone);
a more complete definition of these rock categories is included in appendix 2,
which shows the carbonate classification system used by the Bureau of Geology.

Figure 9 is a structural contour map on the top of the Sunniland Limestone of
the report area. This map suggests that the shell reef in the Sunniland Limestone
of the four wells in the eastern part of the Forty Mile Bend area (wells W-3174,
W-3373, W-3491 and W-8131) was protected from destruction by wave action
by its location in the quiet water of a narrow embayment. Also, the map
suggests that the relatively large thickness of shell rock in well W-5010
accumulated in a structural low as the result of destruction by wave action of
inadequately protected up-gradient shell reefs.
The upper Sunniland Limestone was the commercially productive zone in
both of the Forty Mile Bend field wells. Initial production figures, and lithology
of the producing zone, are:

The lower Sunniland limestone in the Commonwealth, No. 1 Wisehart well, as
shown on cross section A-B (fig. 5) was acidized through perforations at 11,464 -
11,486 feet and pumped 20 BOPD (23 API gravity) plus considerable salt water
(Banks, 1960, p. 1740). This zone was not produced commercially in the
Wisehart well; nor has commercial production been obtained from it in any
Florida well. However, this tight zone contains staining in most of the wells of
the southern part of the State, and it is generally believed to be the source rock
for most of the oil in the upper Sunniland Limestone. Core analyses after Banks
( 1960, p. 1747) of the lower Sunniland Limestone in three wells in the Forty
Mile Bend area are presented in cross sections A-B, B-C and C-D ( figs. 5, 6, and
7), and reveal the zone to have very low permeability. The range of residual
saturations of oil and water from the subject section in the three Forty Mile
Bend area wells was:

14 BUREAU OF GEOLOGY
It will be noted that a high residual water saturation in the Commonwealth,
No. 1 Wisehart well was associated with the accumulation of heavy crude oil.
Also, the electrical log does not indicate a clear oil-water contact. It is possible
that in this tight limestone section the water is not separated from the heavy,
viscous oil, but occurs as connate water which is closely bound with the oil.
Two wells in other areas of southern Florida which have had good drill stem
test recoveries from the lower Sunniland Limestone are:
1. The Humble No. C-1 Gulf Coast Realties Corporation well, which was
located about 4 miles south southwest of Lake Trafford, and in Collier County.
The results of three drill stem tests of the subject section in this well were:
DST No. 1 (11,918 11,938 feet). Top and bottom chokes, 5/8 inch. The tool
was open 28 hours. Recovery was 660 feet of oil (API gravity, 20.4 degrees),and
I50 feet of oil-cut mud. DST No. 2 (11,906 11,950 feet). Top and bottom
chokes, 5/8 inch. The tool was open 36 hours. Recovery was 2,325 feet of oil,
and 528 feet of oil-cut mud. DST No. 3 (11,906 11,950). Prior to this test the
open hole from 11,924 11,940 feet was perforated with 72 shots. Then the
DST interval was acidized with 2,500 gallons. The tool was open 43 hours.
Recovery was 4,320 feet of oil-cut mud, and 2,790 feet of salt water.
2. The Humble, No. 1 Kirchoff well, which was located just south of Fort
Myers, and in Lee County. Results of a drill stem test of the lower Sunniland
Limestone were:
Interval: 11,819 11,928 feet ( 109 feet)
Chokes: 5/8 inch
Tool open: 37% hours
Recovery: 75 feet (1 barrel) of oil with a gravity of 28 degrees, and 225 feet
of oil-and-gas-cut mud.

OFFSHORE

Apparently in anticipation of a possible Federal Oil and Gas Lease Sale of
Gulf of Mexico water bottoms adjacent to Mississippi, Alabama and Florida at
some future date, Florida offshore geophysical activity which began in 1963 has
continued through 1968. The number of permits .for each of the past six years
have been: 5 in 1963, 7 in 1964, 10 in 1965, 13 in 1966, 23 in 1967, and 19 in

Figure 10 shows the location, and a tabulation of lease information, for
Florida's two current offshore State leases. The mineral rights of both of these
leases, containing a combined total of 3,910,460 acres, are held by the Coastal
Petroleum Company, and the annual rental received by the State from these
leases is $49,614.40.
Also, Coastal holds State Mineral Lease No. 248 on 11 lake bottoms of
Florida containing a combined total of 660,736 acres, including Lake
Okeechobee, with 467,200 acres; the annual rental on this lease is $19,985.92.
During December, 1964, an agreement was concluded by Coastal Petroleum
with Mobil Oil Corporation, approved by the Trustees of the Internal
Improvement Fund of Florida, covering Coastal's two leases of State offshore
acreage (No. 224-A and No. 224-B) and of mainland water bottoms (No. 248).
Under this agreement Mobil may earn a 50 percent interest in oil, gas and
sulphur in the three leases, and a 50 percent interest in certain other mineral
rights in certain areas of the two offshore leases when and if it has spent $10
million in exploration and drilling on the properties, or has concluded a
prescribed exploration and drilling program through 1974, whichever occurs
first.

20 BUREAU OF GEOLOGY
The State's jurisdiction extends 10.36 miles from the mainland on most of the
west coast, and 3 miles from shore on the east coast. All of this acreage, with the
exception of that shown on figure 10 to be leased to Coastal, and the relatively
small amount of restricted acreage located offshore from northwestern Florida,
is available for lease.
Current figures on acreage leased on the Florida mainland in addition to that
held under State Lease No. 248 by Coastal are not available to this office. In
1965, however, these figures totaled 3,075,219 acres.
RULES AND REGULATIONS
State Board of Conservation Order No. 7 approved the Polling Agreement for
the unitization of the Sunoco-Felda field, as submitted by the Sun Oil Company,
owner of all of the working interest in the Unit Area.
As provided by Order No. 7 and associated documentation, the terms of
which became effective October 1, 1968, Sun will inject fresh water into the
aquifer of peripheral wells of the Roberts Pool of the Sunoco-Felda field to
conserve reservoir energy. The Roberts Pool is defined as occurring between
11,420 feet and 11,570 feet subsurface in the Sun, No. 1 Red Cattle Company
welt To accomplish this two and perhaps three dry or marginally productive
wells will be converted into injection facilities in the near future. These new
facilities will supplement a single salt water injection well for pressure
maintenance as authorized in 1966 by State Board of Conservation Order No. 4;
this original facility was installed without a unitization agreement.
The unitization accomplished by Order No. 7 was ratified by more than 94
percent of the royalty owners in the Unit Area, which contains 22 producing
wells in the field. Not included are 6 wells located to the west of Sunoco-Felda
field proper.
In connection with this unitization for the Sunoco-Felda field, separate
ownerships within the Unit Area will be combined, with each royalty owner in
the unit to receive an equitable share of the unitized subtances produced.
Unitization as authorized by Order No. 7 will prevent waste of the oil and gas
the correlative rights of interested parties.
NORPHLET (?) DISCOVERY
FLOMATON AREA, ALABAMA
The Humble Oil and Refining Company officially completed their No. 1
Wessner et al Flomaton area discovery well on October 15, 1968. The location
of this test is; Section 14 Township 1 North-Range 8 East (Survey: northeast
quarter of the northeast quarter of the section). This site is about 4 miles north
of the Escambia County, Florida boundary line.

INFORMATION CIRCULAR NO. 65 21
Production was through perforations at 15,320 15,360 feet in a Norphlet (?)
sand section. Calculated absolute open flow was 30 million cubic feet of gas per
day with 1,563 barrels of condensate (48.3 degrees API gravity). Gas
constituents of the gas recovery were: 44.8 percent hydrocarbon gases, 47.3
percent carbon dioxide, 6.9 percent hydrogen sulphide, and 1 percent nitrogen.
This well bottomed 1 feet of salt at a depth of 15,383 feet.
On December 31, 1968 the Humble, No. 1 Loper test, located about 1 1/3
miles south southeast of the discovery well, was drilling below 14,894 feet.

OFFSHORE

Apparently in anticipation of a possible Federal Oil and Gas Lease Sale of
Gulf of Mexico water bottoms adjacent to Mississippi, Alabama and Florida at
some future date, Florida offshore geophysical activity which began in 1963 has
continued through 1968. The number of permits .for each of the past six years
have been: 5 in 1963, 7 in 1964, 10 in 1965, 13 in 1966, 23 in 1967, and 19 in
1968.
For the 19 permits issued in 1968, table 6 records the "estimated" period of
work, the type survey, the permitted, and the approximate area of the activity.
Most of the permits were for work to be concentrated over State and Federal
waters between Apalachicola and Pensacola; and in addition, a considerable
amount of work was to be done along the Florida escarpment extending north
northwest from the Florida keys.
