OIL AND GAS ACTIVITIES IN FLORIDA, 1967

Clarence Babcock
PRODUCTION
SUNOCO-FELDA OIL FIELD
The Sunoco-Felda oil field as shown in figure 1, is the newer of Florida's two
currently producing fields. It was discovered by the Sun Oil Company on
October 9, 1964, and is located in Hendry and Collier counties of southern
Florida. The structural configuration of the field is shown on figure 2; the
character on representative induction-electrical logs of the marker contoured is
depicted on figure 3, a cross section. As of December 31, 1967 this field
contains 26 producing wells drilled on 160-acre spacing, and it appears that nine
dry holes have mostly defined the limits of the field. In 1967 there was no field
drilling.
It is possible that additional fields are present along a northwest-southeast
trend of which the Sunoco-Felda field is a part. At the present time there is
insufficient control to definitely determine if the Sun, No. 1 Red Cattle
Company "B" well located 3/ miles northwest of the main part of the
Sunoco-Felda field, and completed August 2, 1966 with an initial production of
56 BOPD, is an extension of the original field, or is a new field discovery.
The Sunoco-Felda field produces on pump from the microfossiliferous
(miliolitic) limestone of the Roberts zone, which is reached at a depth of about
11,460 feet, and which occurs about 60 feet below the top of the Sunniland
Limestone of Lower Cretaceous (Trinity) age. A large percentage of salt water is
yielded by up-gradient producing wells to the north, where the porosity of the
Roberts zone is reported by the operator to be poor. Woodson R. Oglesby
(1967, p. 278) has suggested that hydrodynamic factors may have contributed
to the oil accumulation in the Sunoco-Felda field.
The yield of the better wells of the field ranges from about 230 to 285 BOPD,
with 19 and 11 percent, respectively, of the total fluid recovery being salt water.
The gravity of this oil is about 24 degrees API. Table 1 shows monthly and
cumulative oil production from the field for the four-year period, 1964-1967,
inclusive. In association with the 1967 production of 982,807 barrels of oil
(table 1), the field also produced 1,184,055 barrels of salt water, which was 55
percent of the total fluid yield.
SUNNILAND OIL FIELD
The Sunniland oil field (fig. 1), discovered in 1943 and operated by the
Humble Oil and Refining Company, is located in Collier County, and about 18
miles south of the Sunoco-Felda field. The structural configuration of the field is
shown on figure 4. The short-lived Forty Mile Bend field is the only additional
discovery of a field similar to the Sunniland field.

INFORMATION CIRCULAR NO. 63

Production in the field is obtained from calcareous rock containing mostly
disoriented macrofossils (rudistids) which is reached at a depth of about 11,500
feet. The trap is a gentle anticline associated with a biostromal reef. Productive
zones begin at the top of the Sunniland Limestone and extend to a depth of
about 65 to 75 feet lower in the section; the lowermost of these zones is
correlative with the productive Roberts zone of the Sunoco-Felda field.
Production from the better wells in the Sunniland field ranges from about 180
to 220 BOPD, with 27 and 37 percent, respectively, of the total fluid recovery
being salt water. The gravity of this oil ranges from 19 to 26 degrees API. Table
2 shows monthly and cumulative oil production from the field for the seven-year
period, 1961-1967, inclusive. Along with the 1967 production of 585,374
barrels of oil (table 2), the field also produced 1,646,215 barrels of salt water,
which is 74 percent of the total fluid yield.
It is significant that the oil production in the years following 1961 increased
markedly over the 1961 figure (table 2). This reflects the opening to production,
beginning in 1962, of deeper zones (C2 and D) of the field in a total of nine
wells (fig.4). The bottom of zone D is only about 65 to 75 feet below the top of
the Sunniland producing interval.
At this time it is thought that 30 million barrels of oil probably is a reasonable
figure for the initially recoverable reserves of the field.
Humble has completed drilling operations on their No. 25 Gulf Coast Realties
Corporation well, which is the only field test drilled in 1967. This well is located
near the northeastern edge of the field. On December 15, 1967 an
induction-electrical log was recorded for this hole, and it has been released by
the company. The structural contours of the field, as shown in figure 4, have
been revised to reflect this additional control. It will be noted that the No. 25
well has a rather favorable structural elevation. As of the end of the year, the
operator was conducting testing operations to determine the productivity of this
well. Since this is an edge location, it is possible that the relatively favorable
structural elevation will not be a guarantee that the parts of the Sunniland
producing interval with a strong water drive will produce.
EXPLORATION
EXPLORATORY DRILLING

As recapitulated in table 3, a footage of 98,432 feet was drilled in 11
exploratory tests in 1967, including an outpost well to the abandoned Forty
Mile Bend field. All of these wells have been plugged and abandoned. Well data
sheets for these test are presented in appendix 1.
GEOPHYSICAL ACTIVITY
The interest in Florida offshore geophysical activity which began in 1964
continues to the present time. In 1967, as shown by figure 5, a total of 23
permits were issued to 8 major oil companies and 2 independents for offshore
geophysical work. Work permitted was: 15 non-conventional seismic surveys

BUREAU OF GEOLOGY

(those which did not use dynamite as an energy source), 4 conventional seismic
surveys, 2 velocity surveys, and 12 gravity surveys. The bulk of this activity will
be in State and Federal waters offshore from the west coast of the State in the
Gulf of Mexico, though some will be in Atlantic water bottoms and mostly over
Federal acreage.
In 1967 there were 51 crew weeks of geophysical activity performed on the
Florida mainland, as follows: 24 in Collier County, 5 in Broward County, 5 in
Lee County, 4 in Charlotte County, 4 in Dade County, 4 in Hendry County, 4 in
Palm Beach County, and I in Santa Rosa County.
LAND
Offshore State leases in 1967 totaled 3,910,460 acres, all under lease to the
Coastal Petroleum Company and located offshore from the west coast of
Florida.
About 3.700.000 acres on the Florida mainland were held under oil and gas
lease during 1967; the corresponding figure for 1965 was 3,075,219 acres. Most
of this leased acreage is located in southern Florida, with 15 percent in Collier
County. It percent in Hendry County, and 9 percent in Palm Beach County.
Leases on this acreage were purchased by 10 major oil companies, with about 60
percent going to Humblc, 11 percent to Texaco, 10 percent to Amerada, and 8
percent to Sun.
In t963 about one million acres of the State's water bottoms offshore from
northwestern Florida and in Choctawhatchec Bay were restricted by the State
from oil and gas leasing at the request of the U.S. Defense Department as shown
on figure 6. This restriction was based upon the premise that offshore drilling in
these areas would interfere with testing delicate sound detection equipment, and
aLso hamper weapons testing. In March, 1967, after receiving the approval of the
Defense Department, the State re-opened to oil, gas and mineral leasing about
half of the originally restricted area. As shown on figure 6, all leasing restrictions
were removed from most of the area re-opened, but part of the re-opened area
remained subject to certain defense activity limitations in connection with
leasing.
PIPELINE FACILITIES
The oil tranmission lines (fig. 7) operated by the Sunniland Pipeline Company
transport about 4,100 barrels of oil a day over the 80-mile route from the
Sunoco-Felda and Sunniland fields to the terminal at Port Everglades. This
volume of crude is the equivalent of 30 oil transport truck loads. Use of the
pipeline has resulted in a saving of as much as 20 cents a barrel as compared with
movement by truck, thus reducing the transportation cost by more than half.
The facility actually consists of two pieces of welded joint steel pipe: a
six.inch diameter pipe from Sunoco-Felda to Andytown, and a four-inch pipe
from Sunniland to Port Everglades. The two pipes extend side-by-side from
Sunniland to Andytown, and over this distance they are "looped", or serve to
tandem. When the "looped" line narrows to the four-inch pipe at Andytown, the

INFORMATION CIRCULAR NO. 63

Production in the field is obtained from calcareous rock containing mostly
disoriented macrofossils (rudistids) which is reached at a depth of about 11,500
feet. The trap is a gentle anticline associated with a biostromal reef. Productive
zones begin at the top of the Sunniland Limestone and extend to a depth of
about 65 to 75 feet lower in the section; the lowermost of these zones is
correlative with the productive Roberts zone of the Sunoco-Felda field.
Production from the better wells in the Sunniland field ranges from about 180
to 220 BOPD, with 27 and 37 percent, respectively, of the total fluid recovery
being salt water. The gravity of this oil ranges from 19 to 26 degrees API. Table
2 shows monthly and cumulative oil production from the field for the seven-year
period, 1961-1967, inclusive. Along with the 1967 production of 585,374
barrels of oil (table 2), the field also produced 1,646,215 barrels of salt water,
which is 74 percent of the total fluid yield.
It is significant that the oil production in the years following 1961 increased
markedly over the 1961 figure (table 2). This reflects the opening to production,
beginning in 1962, of deeper zones (C2 and D) of the field in a total of nine
wells (fig.4). The bottom of zone D is only about 65 to 75 feet below the top of
the Sunniland producing interval.
At this time it is thought that 30 million barrels of oil probably is a reasonable
figure for the initially recoverable reserves of the field.
Humble has completed drilling operations on their No. 25 Gulf Coast Realties
Corporation well, which is the only field test drilled in 1967. This well is located
near the northeastern edge of the field. On December 15, 1967 an
induction-electrical log was recorded for this hole, and it has been released by
the company. The structural contours of the field, as shown in figure 4, have
been revised to reflect this additional control. It will be noted that the No. 25
well has a rather favorable structural elevation. As of the end of the year, the
operator was conducting testing operations to determine the productivity of this
well. Since this is an edge location, it is possible that the relatively favorable
structural elevation will not be a guarantee that the parts of the Sunniland
producing interval with a strong water drive will produce.
EXPLORATION
EXPLORATORY DRILLING

As recapitulated in table 3, a footage of 98,432 feet was drilled in 11
exploratory tests in 1967, including an outpost well to the abandoned Forty
Mile Bend field. All of these wells have been plugged and abandoned. Well data
sheets for these test are presented in appendix 1.
GEOPHYSICAL ACTIVITY
The interest in Florida offshore geophysical activity which began in 1964
continues to the present time. In 1967, as shown by figure 5, a total of 23
permits were issued to 8 major oil companies and 2 independents for offshore
geophysical work. Work permitted was: 15 non-conventional seismic surveys

oil continues eastward to the terminal at Port Everglades with increased pressure
and velocity. The design capacity of the system if the six-inch line were
extended all the way to the port would be 8,500 BOPD, which would
approximately double the present transmission capacity.
There are two booster stations along the line. The first, used in normal
operation, is between Sunniland and Andytown. The second, not used in normal
operation, is between Andytown and Port Everglades.
At Sunniland field the Sunoco-Felda and Sunniland crudes are commingled at
a pipeline junction box. When the oil reaches Port Everglades, it is reconsigned
to the original owners.
The pipelines have been factory-wrapped with a protective coating, and are
buried approximately 24 inches below ground. To prevent corrosion, cathodic
protection is provided by impressing a DC current into the lines at Sunniland
Junction, interceptor canal, and Andytown. The company utilized about 40
anodes across the conservation areas.
The pipelines have been field tested to a pressure of 1,000 psi, with an
operational maximum pressure limitation of 750 psi through the conservation
areas of the Central and Southern Florida Flood Control District. The lines
presently are being operated at about 450 psi, giving an approximate flow rate of
3.7 barrels per minute.
A volume-at-tcmpcraturc measuring system measures flow rates at Sunniland
Junction and Port Everglades, respectively. Any difference between these rates
becomes apparent by means of a telemetry system. The entire pipeline is
automatically shut down after 15/100 percent of the hourly flow rate, or 40
gallons, is lost; repair crews in swamp buggies and air boats can patch the line in
a matter of hours. The operation of the pipeline also is automatically
discontinued if a malfunction develops in either the measuring system, or the
telemetry system.
RULES AND REGULATIONS
In 1967 there were no changes in the legal code governing the conservation of
oil and gas in Florida. As an administrative action, however, the State required
that the Mobil Oil Corporation post a $500,000 bond to assure performance of
remedial action in the unlikely event that the beaches should be contaminated
during the drilling of three tests located offshore from the west coast of Florida.
Also, public concern for beach protection motivated the Department of Natural
Resources to assign an agent to witness the drilling of these wells.
The rules and regulations for drilling of oil wells in Florida, and administrative
oil and gas forms 1 thru 12, closely conform with the pattern suggested by the
Interstate Oil Compact Commission. This material can be obtained without
charge by writing to: Administrator, Oil and Gas Section, Bureau of Geology,
Department of Natural Resources, P.O. Drawer 631, Tallahassee, Florida 32302.

(those which did not use dynamite as an energy source), 4 conventional seismic
surveys, 2 velocity surveys, and 12 gravity surveys. The bulk of this activity will
be in State and Federal waters offshore from the west coast of the State in the
Gulf of Mexico, though some will be in Atlantic water bottoms and mostly over
Federal acreage.
In 1967 there were 51 crew weeks of geophysical activity performed on the
Florida mainland, as follows: 24 in Collier County, 5 in Broward County, 5 in
Lee County, 4 in Charlotte County, 4 in Dade County, 4 in Hendry County, 4 in
Palm Beach County, and I in Santa Rosa County.
LAND
Offshore State leases in 1967 totaled 3,910,460 acres, all under lease to the
Coastal Petroleum Company and located offshore from the west coast of
Florida.
About 3.700.000 acres on the Florida mainland were held under oil and gas
lease during 1967; the corresponding figure for 1965 was 3,075,219 acres. Most
of this leased acreage is located in southern Florida, with 15 percent in Collier
County. It percent in Hendry County, and 9 percent in Palm Beach County.
Leases on this acreage were purchased by 10 major oil companies, with about 60
percent going to Humblc, 11 percent to Texaco, 10 percent to Amerada, and 8
percent to Sun.
In t963 about one million acres of the State's water bottoms offshore from
northwestern Florida and in Choctawhatchec Bay were restricted by the State
from oil and gas leasing at the request of the U.S. Defense Department as shown
on figure 6. This restriction was based upon the premise that offshore drilling in
these areas would interfere with testing delicate sound detection equipment, and
aLso hamper weapons testing. In March, 1967, after receiving the approval of the
Defense Department, the State re-opened to oil, gas and mineral leasing about
half of the originally restricted area. As shown on figure 6, all leasing restrictions
were removed from most of the area re-opened, but part of the re-opened area
remained subject to certain defense activity limitations in connection with
leasing.
PIPELINE FACILITIES
The oil tranmission lines (fig. 7) operated by the Sunniland Pipeline Company
transport about 4,100 barrels of oil a day over the 80-mile route from the
Sunoco-Felda and Sunniland fields to the terminal at Port Everglades. This
volume of crude is the equivalent of 30 oil transport truck loads. Use of the
pipeline has resulted in a saving of as much as 20 cents a barrel as compared with
movement by truck, thus reducing the transportation cost by more than half.
The facility actually consists of two pieces of welded joint steel pipe: a
six.inch diameter pipe from Sunoco-Felda to Andytown, and a four-inch pipe
from Sunniland to Port Everglades. The two pipes extend side-by-side from
Sunniland to Andytown, and over this distance they are "looped", or serve to

It is understood that the operator intended to drill this test to a depth of about 17,000 feet or more. For this reason a
12 1/2-inch hole was drilled to 12, 305 feet, in preparation for the setting of a 9 5/8-inch string of pipe to that depth.
Humble proposed to utilize this unusually long string of 9 5/8-inch casing to protect the producing Sunniland Limestone
reservoir of the Sunniland field, located 3 1/2 miles to the northwest. However, it was decided to terminate the hole
at the final total depth of 12,925 feet, and consequently, the 9 5/8-inch casing was never run.

3. Plugging details
This hole was drilled and plugged, with a cable tool rig. Plugging operations consisted of setting a
temporary brush and rock plug, about 10 feet thick, with the top at 665 feet. On top of this was set
the permanent cement plug, consisting of 95 sacks of cement. The top of this permanent plug was
tagged at a depth of 545 feet.
A steel plate was welded over the top of the surface casing in this hole.
4. This hole will be converted to use as a fresh water well.
