OIL AND GAS ACTIVITIES IN FLORIDA, 1968

ByClarence Babcock

PRODUCTION

Sunoco-Felda Field

The Sunoco-Felda oil field, figure 1, the newer of Florida's two currentlyproducing fields, was opened officially to production by the Sun Oil Companyon 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, 1968this 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 outpostwells.

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 theSunoco-Felda field in 1968 decreased 9 percent below that of 1967. Table 1shows production by months for 1967 and 1968, and cumulative production asof December 31, of each of the respective years.

SUNOCO-FELDA FIELD

The Sunoco-Felda field produces on pump from the Roberts zone, whichoccurs about 65 feet below the top of the Sunniland Limestone (defined by PaulL. Applin, 1960, p. 209) of Lower Cretaceous Trinity Age. The Roberts zoneconsists of microfossiliferous (miliolitic) limestone reached at depths rangingfrom about 11,462 feet to about 11,495 feet. It appears that a permeability trapis responsible for oil accumulation in the field. The producing interval inup-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 producingwells and a dry hole, table 2, all located in the western part of the Sunoco-Feldaarea; data sheets on these wells are included in appendix 1. The two producers,which on initial production pumping tests yielded a combined total of 187BOPD (barrels of oil per day) with 249 barrels of water,. are offsets to acommercially marginal step-out located 3% miles west of the main part of thefield and completed in 1966. The offset dry hole drilled in 1968 in this westernarea defines the limit of the reservoir to the north. At the present time the SunOil Company has a permit to drill yet another offset, to the south, to productionin this area.- This well will be the Sun, No. 28-3 Lee-Cypress "A-l"; it will belocated on acreage under lease to the Humble Oil and Refining Company, anddrilling of the test should commence in the first part of 1969.

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

In the Sun, No. 26-1 Lee-Cypress well the "pay" zone consists of softlimestone which appears to have the porosity characteristics of a classic chalk.The subject section, also, is fairly soft in the Commonwealth and Gulf CoastDriling Company, No. 1 Red Cattle Company well. The porosity of chalk isextremely 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 ofthe Sunoco-Felda area, have a common water drive. But in most cases chalk actsas a barrier to oil migration.

SUNNILAND FIELD

The Sunniland oil field (fig. 1) discovered in 1943 and operated by theHumble Oil and Refining Company, is located in Collier County about 18 milessouth of the Sunoco-Felda field.

Production from the Sunniland field in 1968 decreased 0.67 percent belowthat of 1967. Table 3 shows production by months for 1967 and 1968, andcumulative production for each of the respective years.

At this time it is thought that 35 million barrels of oil probably is a reasonablefigure for the initially recoverable reserves of the field. The oil has a gravity of19 to 26 degrees API (American Petroleum Institute).

Production in the Sunniland field is obtained from calcareous rock containingdisoriented macrofossils (rudistids), which is reached at a depth of about 11,500feet. Productive zones begin at the top of the Sunniland Limestone and extendto a point about 75 feet lower in the section. The lowermost of the five zonshas a bottom-water drive, and is correlative with the productive Roberts zone ofthe Sunoco-Felda field (unpublished cross-sections by Woodson R. Oglesby ofthe Division of Geology).


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 welldrilled in 1968, well data on this test is included in appendix 1. The initialpumping production test on this marginally productive well, figure 3, completedin the upper "C" zone of the Sunniland Limestone, was 62 BOPD in 368 barrelsof fluid. Perhaps the high percentage of salt water in this structurally high edgewell located on the north flank of the field is the result of a tilted oil-watercontact due to production from the field over many years.

On December 17, 1968, the Humble, No. 26 Gulf Coast Realties Corporationwell was permitted. This Sunniland Limestone test, which will be drilled in theearly part of 1969, will be located on the southern flank of the field, and about1,400 feet south of the structurally-high No. 21 well (fig.3), which on IP (initialproduction) test of the "D" zone of the Sunniland Limestone pumped 376BOPD, with 35 percent salt water, The newly-permitted No. 26 test may proveto be about on strike with the following field wells which are relatively low instructural 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 becauseof 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, showsthat the top of the Sunniland Limestone occurs at a sub-sea datum of 11,535feet, which is 15 feet lower than the No. 24 well which is located about 1,500feet to the north. Two zones were drill stem tested in the No. 9 well, with thefollowing results:

First DST (zone "A"). Following acidation, several favorable DST's wererecorded from this zone. The results of the most conservative DST were:

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 theshut-in pressure (4,400 psi), and the flowing pressure (1,500 psi); it appears thatrelatively 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. 9well than there is in producing wells in the field.

Second DST. The total depth of the electrical log is 11,590 feet, which isshallower than the second DST; therefore log correlation cannot be used todetermine the Sunniland "pay" tested. On the basis of interval, however, itappears the tested interval is the lower part of zone "C1 ", or the upper part ofzone "C 2 ". 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 9exploratory wells in Florida (fig. I and appendix 1). Of the total, there waspenetration of 56,316 feet in 7 rank exploratory wells, and 23,158 feet in 2 fieldoutpost wells. One of the outpost wells, the Sun, No. 26-1 Lee-Cypress test, isdiscussed under the "Production, Sunoco-Felda field" heading of this report.The electric-lithologic log, and well data, of the other outpost well, the R-KPetroleum Company, No. 2 1939-1939 S test, are depicted in the cross sectionsand maps of the Forty Mile Bend area, which are presented in the next part ofthe report.

FORTY MILE BEND AREA

Two wells of the abandoned Forty Mile Bend field produced 32,888 barrels ofoil in 17 months in 1954 and 1955. The Lake Trafford-Punta Gorda intervals inthese wells, and in 10 additional tests in the Forty Mile Bend area, all located asshown on the index map of figure 4, are depicted in stratigraphic cross sectionsA-B, B-C, C-D and D-E, figures 5, 6, 7 and 8. The primary purpose of thesesections is to show the top of the Sunniland Limestone, and to integratelithologic, electrical log, and drill stem test and production data for the includedwells.

The carbonate lithology shown in the cross sections of this report are depictedas 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 ofthe report area. This map suggests that the shell reef in the Sunniland Limestoneof 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 actionby its location in the quiet water of a narrow embayment. Also, the mapsuggests that the relatively large thickness of shell rock in well W-5010accumulated in a structural low as the result of destruction by wave action ofinadequately protected up-gradient shell reefs.

The upper Sunniland Limestone was the commercially productive zone inboth of the Forty Mile Bend field wells. Initial production figures, and lithologyof the producing zone, are:

The lower Sunniland limestone in the Commonwealth, No. 1 Wisehart well, asshown 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 theWisehart well; nor has commercial production been obtained from it in anyFlorida well. However, this tight zone contains staining in most of the wells ofthe southern part of the State, and it is generally believed to be the source rockfor 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 FortyMile Bend area are presented in cross sections A-B, B-C and C-D ( figs. 5, 6, and7), and reveal the zone to have very low permeability.

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 possiblethat 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 stemtest recoveries from the lower Sunniland Limestone are:

1. The Humble No. C-1 Gulf Coast Realties Corporation well, which waslocated 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 toolwas open 28 hours. Recovery was 660 feet of oil (API gravity, 20.4 degrees),andI50 feet of oil-cut mud. DST No. 2 (11,906 - 11,950 feet). Top and bottomchokes, 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 theopen hole from 11,924 - 11,940 feet was perforated with 72 shots. Then theDST 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 FortMyers, and in Lee County. Results of a drill stem test of the lower SunnilandLimestone were:

Interval: 11,819 - 11,928 feet ( 109 feet)Chokes: 5/8 inchTool open: 37% hoursRecovery: 75 feet (1 barrel) of oil with a gravity of 28 degrees, and 225 feet

GEOPHYSICAL ACTIVITY

OFFSHORE

Apparently in anticipation of a possible Federal Oil and Gas Lease Sale ofGulf of Mexico water bottoms adjacent to Mississippi, Alabama and Florida atsome future date, Florida offshore geophysical activity which began in 1963 hascontinued through 1968. The number of permits .for each of the past six yearshave been: 5 in 1963, 7 in 1964, 10 in 1965, 13 in 1966, 23 in 1967, and 19 in1968.

For the 19 permits issued in 1968, table 6 records the "estimated" period ofwork, the type survey, the permittee, and the approximate area of the activity.Most of the permits were for work to be concentrated over State and Federalwaters between Apalachicola and Pensacola; and in addition, a considerableamount of work was to be done along the Florida escarpment extending northnorthwest from the Florida keys.

LAND

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 CoastalPetroleum 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.

Figure 10. Offshore Florida State leases, December 31, 1968.


The State's jurisdiction extends 10.36 miles from the mainland on most of thewest coast, and 3 miles from shore on the east coast. All of this acreage, with theexception of that shown on figure 10 to be leased to Coastal, and the relativelysmall 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 thatheld under State Lease No. 248 by Coastal are not available to this office. In1965, however, these figures totaled 3,075,219 acres.

RULES AND REGULATIONS

State Board of Conservation Order No. 7 approved the Polling Agreement forthe 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 ofwhich became effective October 1, 1968, Sun will inject fresh water into theaquifer of peripheral wells of the Roberts Pool of the Sunoco-Felda field toconserve reservoir energy. The Roberts Pool is defined as occurring between11,420 feet and 11,570 feet subsurface in the Sun, No. 1 Red Cattle Companywelt To accomplish this two and perhaps three dry or marginally productivewells will be converted into injection facilities in the near future. These newfacilities will supplement a single salt water injection well for pressuremaintenance 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 94percent of the royalty owners in the Unit Area, which contains 22 producingwells in the field. Not included are 6 wells located to the west of Sunoco-Feldafield proper.

In connection with this unitization for the Sunoco-Felda field, separateownerships within the Unit Area will be combined, with each royalty owner inthe 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 gasthe correlative rights of interested parties.

NORPHLET (?) DISCOVERYFLOMATON AREA, ALABAMA

The Humble Oil and Refining Company offically completed their No. 1Wessner et al Flomaton area discovery well on October 15, 1968. The locationof this test is; Section 14 - Township 1 North-Range 8 East (Survey: northeastquarter of the northeast quarter of the section). This site is about 4 miles northof the Escambia County, Florida boundary line.


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 perday with 1,563 barrels of condensate (48.3 degrees API gravity). Gasconstituents of the gas recovery were: 44.8 percent hydrocarbon gases, 47.3percent carbon dioxide, 6.9 percent hydrogen sulphide, and 1 percent nitrogen.

This well bottomed 1½ 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.
