SUMMARY OF FLORIDA PETROLEUM PRODUCTIONAND EXPLORATION, ONSHORE AND OFFSHORE,

THROUGH 1984

byAlbert V. Applegate

andJacqueline M. Lloyd

ABSTRACT

Each of Florida's seventeen oil fields is described. Descriptionsincluded a brief history of each field along with 1984 andcumulative production data. Geologic information, including astructure map, is presented whenever possible.

Development drilling, exploratory drilling, and geophysical ex-ploration activities are discussed. These discussions indicate cur-rent and future development and exploration areas in Florida.

The appendices include a variety of statistics on Florida oil andgas activity. These include tabulations of 1984 drilling activity, off-shore drilling activity, 1984 and cumulative production data,discovery and oil field data, oil reserve estimates and geophysicalexploration activity.

INTRODUCTION

There are two major oil producing areas in Florida which arefound at opposite ends of the state. One is the "Sunniland trend" inSouth Florida which includes 13 oil fields (nine active, one tem-porarily shut-in, three plugged and abandoned) in a northwest-southeast orientation in Lee, Hendry, Collier, and Dade counties(figure 1). Production is principally from rudistid reefs found in theupper one hundred feet of the Sunniland Formation (figure 2) of Ear-ly Cretaceous age.

Florida's other producing area is in the western panhandle inEscambia and Santa Rosa counties. There are three active oil fieldsand one plugged and abandoned oil field in this area (figure 1). Pro-duction is from Jurassic-age Smackover dolomites and limestonesand Norphlet sands (figure 2).

Since the discovery of Jay field in 1970, northwest Florida hasdominated Florida oil production. Northwest Florida accounts for394,304 million barrels (or 83 percent) of the total 474,976 millionbarrels produced in Florida through December 1984 (see Appendix

.IV). Jay field, the only first magnitude field in the State, has ac-counted for 86 percent of the northwest Florida production and 71percent of the total statewide production.

1984 oil production was down from 1983. During 1984, Floridaproduced 14,461,969 barrels of oil compared to 19,475,574 barrelsfor 1983. This represents a significant decrease (26 percent) in oil

production. Statewide production has been declining since 1979when Jay field began its decline. A comparison of the statewidedecrease in production with Jay field's decrease in production in-dicates Jay Field dominance in Florida oil production trends (seeTable 1).

The discovery of Raccoon Point field in 1978 and its subsequentdevelopment have been the major factors in maintaining thestatewide production decline at a slightly lower rate than that ofJay field (Charles Tootle, 1985, personal communication, FloridaBureau of Geology).

A discussion of each of Florida's seventeen oil fields follows,beginning with Jay field and continuing in geographic order fromnorth to south, as shown on figure 1. A brief history of each field isgiven along with 1984 and cumulative production data. Geologic in-formation, including a structure map, is presented whenever possi-ble. Obviously, geologic information is minimal and maps areunavailable for small fields having only one or a few wells (e.g.,Sweetwater Creek, Baxter Island, and Forty Mile Bend fields).

The field descriptions are followed by three sections on drillingactivity which cover 1) 1984 drilling activity, 2) 1980-1984 Paleozoicdrilling activity and 3) offshore exploratory drilling. The section onoffshore exploratory drilling, along with the final section ongeophysical exploration, yield indications of current and futureareas of petroleum exploration and interest in Florida.

NORTH FLORIDA OIL FIELD SUMMARIES

Jay Field

The Jay field (figures 3 and 4) was discovered in June, 1970, by thedrilling of the Humble St. Regis No. 1 (P-417) in Section 43, T5N,R29W in Santa Rosa County. The well produced from the15,470-15,524 foot interval of the Smackover Formation. The initialtest gauge was as follows:

DATE *BOPD *CHOKE *THP *GOR GRAVITY *BS&W

6/12/70 1712 16/64 3450 1253 50.7 0API 1.3%

*BOPD: barrels of oil per day; CHOKE: surface choke installed forthe purpose of restricting flow and controlling the rate of produc-tion; THP: tubing head pressure (measure of fluid pressure exertedon tubing at the surface, psi); GOR: gas oil ratio, cu. ft/barrel; BS &W: bottom sediment and water.

The Jay field is the largest oil field found in the United States sincethe discovery of the giant Prudhoe Bay field in 1968. Jay field islocated within the "Jay trend" of Escambia and Santa Rosa coun-ties, Florida, and Escambia County, Alabama. The northern exten-sion of jay, in Escambia County, Alabama, is the Little EscambiaCreek (LEC) field. Other fields within the trend include BlackjackCreek field to the southeast, and Fanny Church, Flomaton, and BigEscambia Creek fields in Alabama. Flomaton, which is the only ma-jor Norphlet field in the area, was the first of the Jay trenddiscoveries (1968). The discovery of Jay field was next in June, 1970,followed by Big Escambia Creek field in December, 1971. BlackjackCreek, the last major field in the trend area, was discovered inFebruary 1972 (Ottman, et al., 1978, 1976; Sigsby, 1976). The Jaytrend fields are located on the down-dip side of a normal fault com-plex which rims the Gulf Coast to the west through Alabama,Mississippi, Louisiana, Arkansas, and Texas. It is believed that thisfault complex probably extends to the south-southeast into the Gulfof Mexico. At Jay, the vertical displacement is about 1200 feet. Oilaccumulation at Jay is within an asymmetrically shaped anticlinewith the fault complex forming the eastern barrier to oil migration(figure 4).

The northern seal of Jay field is formed by a porosity barrier inAlabama where the lithology changes from porous dolomite todense micritic limestone. The porosity in the Jay field is due to

dolomitization of the pelletal grainstones and other limestones inan upper regressive section of the Smackover. Early dolomitization,fresh water leaching, and an anhydrite cap rock (Buckner Forma-tion) have helped form a complex, extensive reservoir. Numerousanalyses of the Jay area Smackover, including comparisons withmodern carbonate environments, have been made in attempts tounderstand this complex reservoir (Ottman, et al., 1973 and 1976;Sigsby, 1976; Mancini and Benson, 1980; Lomando, et al., 1981;Vinet, 1984; Moore, 1984; Bradford, 1984).

Ottman, et al. (1973, 1976) compared the facies distribution of theSmackover at Jay with that of the Joulter Cays area in the Bahamas.They found a good correlation between the Smackover at Jay and thestable-flat area (Andros Platform) west of Joulter Cays, with the ex-ception that "...the climate during the closing phase of theSmackover sedimentary cycle was obviously more arid than the pre-sent climate of the Bahamas."

Later models compare the Smackover to the modern Persian Gulf-Trucial Coast sedimentary environment (Lomando, et al., 1981; Brad-ford, 1984; Moore, 1984; Vinet, 1984). These models take into accountthe more arid depositional environment of the Upper Smackover.They also are compatible with the physiographic, carbonate rampmodel presented by Ahr (1973). The ramp, as defined by Ahr, is "an in-clined platform that extends basinward without a pronounced breakin slope." The Jurassic Smackover and Cotton Valley are presentedas ancient examples of the ramp model; the Trucial Coast of the Per-sian Gulf is one of the modern examples. In contrast, the BahamasBanks, especially the Andros Island area, is an example of the car-bonate shelf depositional model.

Consideration of diagenetic information in relation to the deposi-tional models indicates the influence of original facies distributionon later porosity development in the Smackover (Sigsby, 1976; Brad-ford 1984; Vinet, 1984). The formation of Smackover hydrocarbonreservoirs as a result of original depositional environment, subse-quent dolomitization of select facies, and present day structure issummarized by Bradford (1984) as follows:

"The Smackover carbonates have both primary intergranularporosity and secondary oomoldic and intercrystalline porosi-ty which resulted from dolomitization of the upperSmackover grainstones and underlying mudstones. Theporous grainstones provided a conduit for the dolomitizingfluids and only those mudstones associated with thegrainstones were dolomitized. In areas...where nograinstones were deposited, the mudstones were notdolomitized. Therefore, the original depositional environmentprovided an important control over later porosity-formingdolomitization. The overlying Buckner anhydrite provided aseal to this reservoir facies.


The original depositional environment was, in turn, controll-ed by topographic highs which were the result of salt move-ment. Salt movement during the Late Smackover was minor,but provided the slight differences in elevation needed forhigher energy conditions to develop...A map of present-daystructure shows that the undolomitized lagoonal mudstonesare now structurally the highest in the area. These dense limemudstones have no porosity and therefore contain nohydrocarbons. But hydrocarbons are present beneath thislime mudstone in the underlying Norphlet Sandstone inFlomaton field where the dense mudstone forms a seal. InBig Escambia Creek field, hydrocarbons occur in updipregions of the porous dolomitized grainstones andmudstones. The contact between dolomitized and non-dolomitized rock provides the eastern boundary to theSmackover Field."

Reservoir energy at Jay is furnished by a combination of dissolvedgas and water drive. Water flooding and injection of nitrogen gashave more than doubled initial recovery estimates from these fields.

In his study on Florida oil reserves in 1978 (Appendix VII) Dr.Charles Tootle (Florida Bureau of Geology) estimated the original oilin place in the Jay field (Florida only) to be 763,129,638 barrels, andproductive acres (Florida only) to be 13,021. The estimated recoveryfactor assigned this field was 42 percent with original recoverable oilin place of 320,514,448 barrels. By year-end 1984 Jay had produced atotal of 339,382,000 barrels of oil. In January 1985, oil production forthe month was 580,087 barrels of oil, and 3,866,323 barrels of waterfrom the 50 remaining producing wells. A total of 113 producingwells, 13 dry holes and 15 service wells were drilled throughDecember, 1984.

A key to the successful exploration and development of the Jay-Little Escambia Creek (Alabama) fields was the unitization of thefields. This was made possible by coring the wells, analyzing thecores, and combining this information with bottom hole pressuredata, porosity log information, and other data to arrive at a highlysuccessful reservoir management program and accurateassignments of equity to operators and royalty owners (Schirer, etal., 1978; Langston, et al., 1981; Langston and Schirer, 1985).

Blackjack Creek Field

The Blackjack Creek field (figure 5) discovery well was the HumbleOil and Refining Co. (now Exxon) St. Regis Paper Company 13-3 well(P-523) drilled in Section 13, T4N, R29W, Santa Rosa County. The wellwas completed February 14, 1972, as a producer in the Norphlet For-mation in the 16,120-16,130 foot interval. The initial test gauge was asfollows:

Due to limited productivity and water production caused by a badcement job in the Norphlet Formation, the well was recompleted as aSmackover producer in the 15,790-15,900 foot interval. Only 35,644 bar-rels of oil were produced from the Norphlet Formation. Initial gaugefor the Smackover on January 22, 1975, was as follows:

The trapping structure for the Blackjack Creek field is an anticlinelocated about eight miles southeast of Jay field on the downthrownsouthwest side of a down-to-the-basin normal fault which has about1,200 feet of throw at Jay (figure 5). The field was originally known asthe Joulter Cays field (named for a carbonate bank in the Bahamas)by Exxon geologists due to its dolomitized oolites, which furnishedmuch of the porosity.

Reservoir energy in the field is derived from a combination of gasand water drive. Secondary recovery was furnished by a water floodand tertiary recovery by the injection of nitrogen.

By year end 1984,19 producers, and four dry holes had been drilledin the Blackjack Creek field. Total production was 50,463,000 barrels.All of this production, except for about 160,000 barrels producedfrom the Norphlet Formation, was from the Smackover Formation ofUpper Jurassic age. During December, 1984, the field produced190,546 barrels of oil and 669,000 barrels of water from nine wells.Productive acreage totals 5720 acres (Appendix VI), and of the100,500,000 barrels of oil (Appendix VII) calculated to be in place,over 50 percent has been produced to date.

Mt. Carmel Field

Mt. Carmel field (figure 6) was discovered on December 19, 1971,by the Louisiana Land and Exploration Company (LL & E). Thediscovery well was the LL & E - Finley Heirs 39-3 (P-504) located inSection 39, T5N, R29W, Santa Rosa County. The field is approximate-ly one mile east of Jay field and is separated from Jay by the FosheeFault system (figures 5 and 6). Productive area is estimated at 481acres (Appendix VI).

Initial production was 1,440 barrels of 470 API oil per day and 1,195thousand cubic feet gas per day with 0.1 percent BS&W. The produc-ing horizon was from 15,260 to 15,325 feet in sandstone of the Nor-phlet Formation. The horizon was perforated from 15,260 to 15,280feet.

There is currently one producing well in the Mt. Carmel Field. As ofthe end of 1984, the field had produced 4,444,692 barrels of oil and4,624,562 thousand cubic feet of gas, with 79,557 barrels of oil and131,783 thousand cubic feet of gas produced during 1984. Productionduring December 1984 was 11,429 barrels of oil, 26,722 thousandcubic feet of gas, and 23,304 barrels of water.

Sweetwater Creek Field

Sweetwater Creek Field (see figure 3) was officially discovered onApril 22, 1977, with the successful flow test of the Houston Oil andMinerals Corp. W.M. Stokes 15-2 No. 1 Well (P-881) in Section 15, T5N,R26W, Santa Rosa County. In the initial test the well produced 624barrels of 43.50 API oil and only a trace of water from a Smackoverlimestone interval from 14,299 to 14,340 feet. This test data, alongwith the well location (approximately 18 miles east of Jay field) spur-red rumors that a "new Jay" field had been discovered. Rumors prov-ed to be false and offsets to the south and east of the discovery wellwere dry. The field produced a total of 13,695 barrels of oil during itsentire lifetime. The discovery well was the only producer at Sweet-water Creek field. In its final year of production (1980) the well pro-duced 1,456 barrels of oil. It was plugged and abandoned inDecember, 1980, after it began producing 100 percent water.

SOUTH FLORIDA OIL FIELD SUMMARIESSunoco Felda Field

The Sunoco Felda field (figures 7 and 8), located in Hendry andCollier counties, was discovered in July, 1964, by Sunoco when theydrilled the discovery well, the No. 2 Red Cattle (P-315) in Section 32,T45S, R29E in Hendry County, Florida. The discovery well of the se-cond commercial oil field in Florida was drilled 21 years after thediscovery of the Sunniland Oil field and was located on a combina-tion of seismic and subsurface data (Tyler and Erwin, 1976). In June,1954, the Commonwealth No. 3 Red Cattle (P-191) was drilled in Sec-tion 25, T45S, R28E, in Hendry County. A drill stem test of this well inthe 11,435-11,492 foot interval of the Sunniland Formation recovered1,090 feet of clean oil, 350 feet of brackish water and 9,060 feet of saltwater. It was decided that a commercial completion could not bemade. The discovery well for the field was slightly over two miles tothe southeast of this test, but was drilled over ten years later. In thedevelopment of the field, a commercial oil well, the Sun No. 1 RedCattle Co. "A" 25-1, Section 25, T45S, R28E (P-369) was drilled about1,000 feet southwest of P-191.

The depositional environment in the Early Cretaceous was one ofa clear shallow subtropical sea and a very slowly subsiding sea bot-tom. There was a regional dip to the southwest of about 20 feet permile. The time interval was characterized by transgressions andregressions of the sea as shown by the carbonate-evaporite se-quences. A localized build up of algal plates, rudistids, foraminifera,gastropods, pellets, and other organic debris into mounds or podswas responsible for the Sunoco-Felda oil field. The trap isstratigraphic and is due to a porosity and permeability barrier to thenortheast which prevents migration of the oil up-dip (Tyler and Erwin,


1976; Means, 1977).A permit summary shows a total of 32 producing wells and 14 dry

holes had been drilled at the close of 1984. A 1978 study made by Dr.Charles Tootle (Appendix VI) showed a surface area of approximately3,840 acres; the average thickness of the producing horizon was 12feet, the oil in place was 32,368,421 barrels, and producible reserveswere 12,300,000 barrels (Appendix VII). Cumulative productionthrough year-end 1984 totaled 10,918,000 barrels of oil.

Oil production for the year 1984 was 227,939 barrels, and water pro-duction was 2,258,956 barrels. There were 12 producing oil wells inthis field at year-end 1984.

The well was completed in the 11,492-11,496 foot interval ofthe Sunniland Formation on October 13,-1977. Samples show a par-tially dolomitized fossil hash with about ten feet of oil staining. Thecompensated formation density log indicated approximately 20 per-cent porosity for an eight foot interval.

In an initial production test taken October 24, 1977, the discoverywell gauged 281 barrels of oil per day and 53.6 barrels of water on apump test. The well was located on a small subsurface feature be-tween West Sunoco Felda field and the Sunoco Felda field (figure 8).At year-end 1984, there were three producers and six dry holes.

Cumulative production at year-end 1984 from the Mid-Felda fieldwas 826,000 barrels of oil. Production during December was 9,467barrels of oil and 29,066 barrels of water. Productive acreage is ap-proximately 480.

Townsend Canal Field

Townsend Canal field is located in Hendry County, approximatelythree miles north of Mid-Felda field, within the Sunniland Trend(figure 7). It was discovered on June 27, 1982, with the first produc-tion test of the Natural Resource Management Corp. - A. Duda &Sons Well No. 2-3 (Section 2, T45S, R28E, P-1070). The test produced160 barrels of 28.40 API oil per day and 42 barrels of water per day.Production was from the Sunniland Formation between 11,416 and11,430 feet. Productive area is estimated to be 640 acres (AppendixVI).

Four wells are currently producing at Townsend Canal field. Twowells were completed during 1984. The Natural Resource Manage-ment Corp. - Duda (Evergreen) No. 7-2 (P-1116), located in Section 7,T45S, R29E, was completed as a saltwater disposal well. The NaturalResource Management Corp. - A. Duda & Sons No. 3-2 (P-1151) inSection 3, T45S, R28E, was completed as a potential producer.

Total production for the Townsend Canal Field, as of the end-of1984, was 124,861 barrels of oil. Production during December 1984was 9,272 barrels of oil and 26,221 barrels of water.

Lehigh Park Field

The discovery well for the Lehigh Park field (figure 9) was the Exx-on Consolidated -Tomoka No. 22-4 (P-712) drilled in Section 22, T44S,R26E in Lee County, Florida.

This is the most northwesterly field in the Sunniland trend. Thediscovery well was completed in the 11,389-11,394 foot interval of the

Sunniland Formation. Initial production was 490 barrels per day of27.60 API oil with BS&W of 48 percent. Completion date was July 30,1974.

There are presently five producing wells in the field. The discoverywell (P-712) was abandoned and a deviated well (P-712A) drilled at thesame surface location to produce higher on the structure. A total ofnine dry holes were drilled to delineate the field. All of the producingwells are deviated because bottom-hole locations are beneath thetown-site of Lehigh Park.

Production through year-end 1984 was 4,275,000 barrels of oil. Dur-ing December 1984, the field produced 29,046 barrels of oil. Percen-tage of oil to total fluid is 7.8 percent.

The field has an areal extent of 804 acres and the estimatedthickness of the pay interval is 16.8 feet. Dr. Charles Tootle (personalcommunication, 1983) calculated original oil in place at 7.6 millionbarrels (Appendix VII) and recoverable oil at 4.6 million barrels.

West Felda Field

The West Felda Field (figure 8) was discovered August 2, 1966,with the drilling of the Sun-Red Cattle 21-3 well (P-371) in Section 21,T45S, R28E, Hendry County.

The West Felda field is the largest oil field discovered in southFlorida. The trap is partially stratigraphic but also has closure (figure8). The discovery well was drilled on the northeast flank of the fieldand there is definite dip reversal to the northeast, which was not pre-sent at Sunoco Felda. The West Sunoco Felda was in a more normalmarine environment than Sunoco Felda and the energy level washigher. Porosity and permeability were thus higher in the West Feldafield with average porosity of 20 percent and average permeability of80-100 millidarcies. Proven acres in the field are approximately 7,500.The average oil pay thickness is 17 feet, and original recoverable oilin place is estimated to be 50,000,000 barrels. (Appendices VI andVII).

At year-end 1984, cumulative oil production from the West Feldafield was 37,004,000 barrels of oil from 26 producing wells. During themonth of December, 1984, oil production was 106,197 barrels andwater production was 674,675 barrels. Oil production was 13.6 per-cent of total fluid.

In 1970 Humble (now Exxon) drilled a wildcat well in Lee County,the Humble - Lehigh Acres 14-2 in Section 14, T45S, R27E (P-407).This well was originally considered to be the discovery well for a newfield (named the Lehigh Acres field) but was later found to be withinWest Felda field.

This well encountered on altered quartz diabase at 15,625 feetbelow MSL (Barnett, 1975) with age of 163 million years (Exxon). Inthe Lehigh Acres well, 70 feet of dolomite were found in the


12,588-12,684 foot interval of the Brown Dolomite Zone. Most of thisdolomite was very fine grained and non-porous. Approximately tenfeet of this dolomite were estimated to have had porosity andpermeability capable of oil production had it been oil saturated.

During 1984 four wells were drilled in the West felda field. Two ofthese were completed as potential producers: 1) the Exxon Turner20-2 (P-1153), Section 20, T45S, R28E, and 2) the Exxon ConsolidatedTomoka Land 13-5 (P-1132), Section 13, T45S, R27E.

Lake Trafford Field

The Lake Trafford field (figure 10) was discovered by Mobil OilCorp. on the Baron Collier Jr. lease in Section 9, T47S, R28E in CollierCounty about one and one-half miles southwest of Lake Trafford. Thediscovery well IP-401) was completed March 30, 1969.

The field is of special interest as it is a one-well field producingfrom the basal part of the Sunniland Formation. The Sunniland top inthe discovery well is at 11,640 feet (11,600 feet below MSL) and thePunta Gorda top is at 11,895 feet (11,855 feet below MSL). The Sun-niland was perforated in the 11,800-11,892 foot interval with an initialpumping production of 118 barrels of oil per day, and 78 barrels ofwater per day after the well was acidized with 2,500 gallons of acid.The gravity of the oil was 25.60 API. Subsequently, the well wassqueeze cemented to shut off water from above the perforations, re-perforated and re-acidized. Offsetting locations northwest andsoutheast of the discovery well were dry holes.

On July 18, 1977, Mobil sold this field to the Kanaba Corporation.By the end of 1984, the field had a cumulative production of 242,000barrels of oil. Oil production during 1984 was 11,963 barrels. Thisfield is unique in south Florida as it has not produced water since theoriginal bad cement job was repaired by squeeze cementing and re-perforating.

According to Jim Richter (personal communications, 1985), whowas exploration manager of Mobil at the time the discovery well wasdrilled, and is now president of Kanaba Corporation, the well sitegeologist described cored material from the producing zone as "rub-ble". The geologist noted that there were burrows in this argillaceouslimestone "rubble" which were probably made on a mud flat and ad-ded to the porosity of the rock. Mr. Richter felt that it was a combina-tion of this burrowing and fracturing which was responsible for thedevelopment of the producible permeability and porosity. John A.Means (1977) also notes that the Sunniland limestone produces froma fractured zone in the Lake Trafford field.

Seminole Field

The discovery well for the Seminole field (figure 7) was the Weiner-Oleum Corporation well (P-662) in Section 12, T48S, R32E, in HendryCounty. Completion was made in the 11,415-11,420 foot interval ofthe Sunniland Formation on November 14, 1973. Initial productionwas 26 barrels of 25.40 API oil per day and eight barrels of water perday. This non-commercial three-well oil field was abandoned in 1978after producing a total of 84,755 barrels of oil.

Sunniland Field

The Sunniland Oil field (figure 11) was officially discovered.inNovember, 1943, by the Humble Oil and Refining Company (now Exx-on) at Sunniland Siding in Collier County. The well, GCR No. 1 (P-42),was in Section 29, T48S, R30E. Completion was made in the Sun-niland Formation in the open hole interval of 11,597 - 11,626 feetbelow seven-inch casing which was cemented at 11,597 feet. Initialproduction was 97 barrels of 200 API oil per day and 425 barrels ofwater per day by pumping.

The well was drilled on a prospect outlined by magnetometer,gravity meter, seismograph and core drill. Seismic work was con-sidered poor due to the "boulder zone", an interval of highly porouscarbonates usually encountered between 1,300 and 3,500 feet. Coredrilling data also resulted in false information. Exxon was mappingstructure on the Ocala by drilling core holes about a mile and a halfapart in selected areas. One of these core holes encountered asinkhole in the Ocala and when it was compared to the one hole inthe south it was falsely interpreted as a reversal, as this was notfound deeper in the section.

After drilling GCR No. 1, Exxon drilled the Humble GCR No. 2 inSection 30, T48S, R29E. This well was structurally low and about onemile west of the original discovery. It was a dry hole. The third welldrilled was the Humble GCR No. 4 (P-35) in Section 20, T48S, R30E.This well was about one and one-half miles north of GCR No. 1 andwas within the field limits of the Sunniland Field. It was the truediscovery well. Through December 1984,25wells, including the Hum-ble GCR No. 1, have produced oil in this field. There were also ten dryholes. Production in the field is from various porous zones in rudistid"mounds" in the upper 60 feet of the formation. These rudistids (nowextinct) were pelecypods. A modern equivalent of a rudistid would be ian oyster. The structure map (figure 11) for the Sunniland field shows !a northwest-southeast trending dome about four miles long and twomiles wide with closure of about 40 feet. It is not believed that therehas been any folding or faulting in this field, and no structure isnoticeable in the underlying Punta Gorda Formation. The explana-tion for this dome is that as the sea gradually rose, growth of therudistid beds in the upper Sunniland kept up with the rising sea level.When the seas retreated and the Lake Trafford Anhydrite formed, itwas thinnest where the thick rudistid beds of the Sunniland were pre-sent.

At year-end 1984 six wells were producing and 12 wells were shut-in at Sunniland. Total oil production for the year was 160,454 barrelsof oil and 2,975,137 barrels of water. Over 18.5 barrels of water wereproduced for each barrel of oil, or about 5.4 percent of total fluid pro-duction was oil. Cumulative oil production through 1984 was

18,198,000 barrels of oil with a gas-oil ratio of just under 100.The original Sunniland well, GCR No. 1 in Section 29 was open to

production to the depth of 11,626 feet (11,592 feet below MSL) whichis 34 feet below the oil-water contact shown on a Humble structuremap of the Sunniland Field. This oil-water contact appears to beabout the same as the Bear Island well GCR No. 34-3 in Section 34,T48S, R30E (P-780) which lies about 9,000 feet to the southeast. Itwould thus appear that Exxon had found Bear Island in 1943 insteadof Sunniland even though Bear Island was not officially discovereduntil 1972 by Tribal Oil on an Exxon farm out.

In 1981 Exxon drilled the No. 20-2 Collier Co. well (P-1042, Section20, T48S, R30E) to 17,200 feet in the Sunniland field. They en-countered a weathered granite at 17,092 feet, after drilling the entireLower Cretaceous and Jurassic sedimentary section below the Sun-niland. This deeper pool wildcat was then completed in the Sun-niland.


Bear Island Field

Bear Island field (figure 12) was officially discovered on December5, 1972, with the completion of the Exxon-Gulf Coast Realties 2-4(P-563) well in Section 2, T49S, R30E. The "real" discovery of BearIsland may have actually occurred in 1943 with the completion of the"Sunniland discovery well". A discussion of this well and itssignificance in the history of these two fields is included in thepreceding Sunniland field section of this report.

Bear Island is within the Sunniland trend and is located approx-imately two miles southeast of Sunniland field (figure 8). The officialdiscovery well pumped 132 barrels per day of 260 API oil and 545 bar-rels per day of water from perforations between 11,589 and 11,595feet in Sunniland carbonates.

The deepest well in Bear Island field, the Exxon-Gulf CoastRealties No. 12-2, (P-727, Section 12, T49S, R30E), was completed onApril 21, 1977. It bottomed in the basal clastics (base of the WoodRiver Fm.) at a total depth of 17,254 feet. The well had an initial pro-duction of 12 barrels of oil and 67 barrels of water per day from theSunniland Formation between 11,597 and 11,607 feet. It alsopenetrated the Brown Dolomite Zone of the Lehigh Acres Formationbetween 12,812 and 12,872 feet with a net dolomite thickness ofseven feet (Applegate, 1984). In this well, the dolomite had no porosi-ty.

There are currently 24 producing wells in Bear Island field. Twodevelopment wells were completed during 1984: the Exxon - CollierCo. No. 2-10 (P-1118) in Section 1, T49S, R30E and the Exxon - CollierCo. No. 2-11 (P-1119) in Section 2, T49S, R30E. Both wells were com-pleted as potential producers.

The field produced a total of 8,516,000 barrels of oil as of year-end1984, with 772,000 barrels produced during 1984. Production duringDecember 1984 was 67,181 barrels of oil and 363,571 barrels of water.

The structure map of Bear Island field (figure 12) indicates anorthwest-southeast trending dome about 4.5 miles long and 2.5miles wide with a closure of about 55 feet. The field is estimated tohave 2,880 productive acres (Appendix VI), an average pay thicknessof 11 feet, and 14.7 million barrels of original recoverable oil in place(Appendix VII).

Pepper Hammock Field

Pepper Hammock is a recently named, but inactive field, in CollierCounty (figure 7). The discovery well, the Exxon Corp. - Collier Co.23-1 (P-897), is located in Section 23, T49S, R30E, approximately oneand one-half miles south of Bear Island field. This is the only well atPepper Hammock; it is currently shut-in pending results of further ex-ploratory drilling.


The initial production test on September 28, 1978 (the officialdiscovery date), yielded 20 barrels per day of 270 API oil and 206 bar-rels per day of water. Production was from Sunniland limestones at11,629 to 11,633 feet. A total of 323 barrels of oil were producedbefore the well was shut-in in October, 1978.

Baxter Island Field

Baxter Island is a one-well, abandoned field located approximatelyeight miles southeast of Bear Island field (figure 7). The single pro-ducer and discovery well was the Diamond Shamrock - Gerry Bros.Ltd. 31-3 (P-865) located in Section 31, T49S, R32E, Collier County. Inits initial production test on August 11, 1977, the well pumped 35 bar-rels of 22.4 o API oil and 220 barrels of water per day. Production wasfrom the Sunniland Formation at 11,512 to 11,515 feet. The field pro-duced a total of 1,859 barrels of oil. Production during 1978, before itwas shut in, was only 813 barrels of oil. The well was plugged andabandoned on January 12, 1980.

Raccoon Point Field

Raccoon Point field is the southeastern-most active field in theSunniland trend (Figure 7). The field includes approximately 1,600productive acres (Appendix VI). Its discovery well was the Exxon-Oleum Corporation No. 33-4 (P-829) drilled in Section 33, T51S, R43E,in Collier County.

Initial production was from the 11,410 - 11,414 foot interval of theSunniland Formation. The first reliable production test was madeJune 20, 1978, when the discovery well pumped 57 barrels of 23.30API oil per day and 845 barrels of water per day.

The preliminary structure map (figure 13) of Raccoon Point field in-dicates a dome trending approximately north-south. It appears to beat least two miles wide and two to three miles long; however, thelimits of the field cannot yet be defined. Productive acreage andreserves have not been estimated for this relatively new oil field. It isinteresting to note that to date there have been no dry holes drilled inthe Raccoon Point field area.

There are currently nine producing wells in the Raccoon Pointfield. Three development wells were completed during 1984: the Exx-on -Oleum Corp. (P-1061), the Exxon Corp. -Oleum Corp. (P-1082), andthe Exxon Corp. - Collier Land and Cattle Corp. (P-1130). All threewells are located in Section 34, T51S, R34E. They were completed aspotential producers.

The production total for Raccoon Point field, at year-end 1984, was448,580 barrels of oil. Production during December 1984 was 48,537barrels of oil and 59,123 barrels of water.

Forty Mile Bend Field

Commonwealth Oil Company drilled the Wiseheart - State Boardof Education No. 1 wildcat (P-167) in Section 16, T45S, R35E in DadeCounty. The well was completed January 27, 1954, in the 11,322


-11,339 foot interval of the Sunniland Formation. The well pumped anestimated 76 barrels of 21.30 API oil with 56.3 percent BS & W. It waslocated 50 miles southeast of the Sunniland field (figure 8). A studyof the core in the open interval shows that it is a partially to fully oil-saturated, finely crystalline dolomite and limestone with pin-pointporosity which does not appear to be commercial.

The second well in the Forty Mile Bend field, completed in 1954,was the Gulf Oil - No. 1 State of Florida, lease No. 340, (P-182). Thiswell, located in Section 18, T54S, R36E, about three and one-quartermiles east of the original discovery well, was completed as a pump-ing well in the 11,327-11,334 foot interval of the Sunniland. The initialgauge was 112 barrels of oil per day. The oil gravity was 21.70 API,and the BS & W was 75 percent.

The two wells comprising Forty Mile Bend field were actually overnine miles apart (figure 8) and could not have produced from thesame trap. Both were abandoned in 1956, after producing only 32,888barrels of oil in about 17 months in 1954 and 1955. Low oil gravitycaused by insufficient maturation temperature, and low porosity andpermeability in the Sunniland at these locations made this field non-commercial. In addition, a V2-inch hole was found in the casing ofthe Gulf well (P-182) at 10,045 feet. This was above the cement behindthe casing and below the pump seat inside the casing. This couldhave caused excessive water flow and thus shortened the productivelife of the well.

DRILLING ACTIVITY

1984 Wildcat and Field Development Drilling

As the following table indicates, 1984 Florida oil drilling activitywas about the same as the preceding five years, although there wereslightly fewer wells drilled during 1980 and 1982.

Wildcat drilling during 1984 (see Appendix I) was concentrated innorthwest Florida, primarily in Santa Rosa County (four wells) andEscambia County (two wells), with one well in Walton County.Jurassic Smackover and Norphlet formations were the exploratorytargets in this area. The three wildcat wells drilled in south Floridawere targeted for the Sunniland Formation. The remaining wildcat,drilled in Dixie County, was a Paleozoic test. Paleozoics in northFlorida are presumed to be closely related to Paleozoic rocks of

28 BUREAU OF GEOLOGY '

West Africa (Cramer, 1971,1973). West African production from theserocks has spurred exploratory interest in Florida. More informationon Paleozoic drilling can be found in the next section of this report.

The single successful wildcat drilled during 1984 is located in Sec-tion 19, T5N, R31W, in Escambia County. The degree of success isunknown at this point because data for this well is still confidential.Wildcat success ratio for 1984 is 1/11, or approximately nine percent.This appears to be a reasonably good success ratio; however, withso few wildcats drilled per year, long term averages yield morerepresentative values. Wildcat drilling over the last five years yieldedtwo successful wells out of a total of 56 drilled (approximately 3.6percent).

Fifteen field wells were drilled during 1984. Thirteen were develop-ment wells and two were service wells (saltwater disposal). Of thethirteen development wells, ten were completed as potential pro-ducers and three were plugged and abandoned as dry holes. Three ofthe producers were drilled in northwest Florida to the Smackover.Seven were South Florida-Sunniland wells. All three dry holes werelocated in south Florida - one at Lehigh Park field and two at WestFelda field-and were drilled to the Sunniland.

1980 - 1984 Paleozoic Drilling Activity

The Paleozoics in Florida range from Devonian to Ordovician orCambrian in age, and faunally are closely related to African rocks(Cramer, 1971, 1973). Production from the West Africa rocks spurredinterest in Florida; however, the Florida sandstones, which are inthe lowermost part of the section, are extremely indurated and havevery little porosity or permeability. In addition to these negative fac-tors, the Triassic breakup of the African and North American con-tinents was accompanied by much igneous activity and thePaleozoics of Florida were heavily intruded by basic igneous rocks.

Amoco drilled five Paleozoic wildcat wells in north Florida be-tween 1980 and 1984. These wells were drilled in Taylor, Madison,Lafayette, and Dixie counties (figure 14). All were dry holes, andnone had any shows of oil. In addition to these wells, Amoco par-ticipated in a 10,000-foot Paleozoic well in Camden County,Georgia, just four miles north of the Florida line. Amoco held overone million acres under lease in 1984, mainly in Taylor, Dixie,Lafayette, and Levy counties, but many of these leases have beendropped, and according to Amoco geologists, there are no plans todrill any more wells in north Florida.

In addition to Amoco, other oil companies with substantial landholdings include Star Petroleum, Pennzoil, Aminoil, and Exxon. Ex-xon has substantial holdings north of the Florida border in Echol's,Lowndes, and Clinch counties, Georgia, and has run many seismiclines in Madison and Hamilton counties, Florida. Exxon also drilled


a dry hole in Early County, Georgia, in 1984. This well was drilled toa total depth of 9,176 feet. Most of the acreage in neighboringJackson County, Florida, was under lease at the time this well wasdrilled.

During the period of very active leasing, which began before thefirst well was drilled by Amoco, the price of leases gradually rosefrom about one dollar per acre bonus money to a maximum of about20 dollars per acre, but has since declined as leases are beingallowed to expire.

Possible Future Oil and Gas Fields - Offshore Exploratory Drilling

Twenty miles to the west of the Florida - Alabama boundary, inAlabama state waters, lies the Mary Ann gas field (figure 14). Thisfield is in Mobile Bay and was discovered in the Norphlet Formationby Mobile Oil in 1979. Mobil has six Norphlet wells, and Exxon hastwo Norphlet wells in the Mary Ann field and an active drilling cam-paign is being pursued in this area.

There are at present (year-end 1984) four Norphlet wells outsideof the Mary Ann field limits completed or in the process of comple-tion in the Norphlet with no dry holes drilled at the present time.Some of these wells have tested in excess of 30 million cubic feet ofgas per day. This area will add significantly to the United States' totalgas reserves and this Norphlet gas may extend to the east intoFlorida waters.

A Jurassic test, the Getty Oil State Lease 2338, Well No. 1(P-1097), in East Bay, Santa Rosa County, Florida, was drilled in1983 to a total depth of 18,011 feet. The Smackover was tested butproduced only saltwater in the 17,482-17,530 foot interval. Two testsin the 17,405-17,411 and 17,328-17,411 foot interval of theSmackover produced only saltwater. The thick, porous, andpermeable Norphlet Formation and underlying Louann Salt, whichtogether are responsible for the prolific production in the Mobilearea, were very thin in this well.

Gulf of Mexico Eastern Planning Area

After a long history of drilling dry holes off Florida (Appendices IIand III and figure 14) in state and federal waters in the eastern Gulf ofMexico, a sale of tracts in this relatively unexplored area onJanuary 5, 1984, attracted a relatively low $310,600,000 for 156tracts of 5,760 acres each. The high bid of $31,877,000 was made byShell and Amoco for a block on the top of the Destin Dome. Drilling

up to this time had taken place only on the flanks of the structure.The second highest bid of $16,578,000 was made for Destin Dometract 159 (figure 14) by Conoco and Chevron. The third highest bid of$15,486,000 was made by Mobil, Tenneco and Sohio for tract 948 inthe Pensacola area (figure 14). The amount paid for this blockreflects the success of Mobil and Exxon in the Mobile area to thewest.

In the original Destin Dome drilling, around 1975, a total of ten dryholes were drilled in the Destin Dome area. Nine of these wells wereon the Destin Dome and one well drilled by Gulf Oil was about 80miles to the southwest of the dome (figure 14). Three of the wells onDestin Dome drilled by Exxon (OCS-G-2486), Amoco (OCS-G-2502),and Sun (OCS-G-2490) penetrated the Jurassic Smackover and Nor-phlet formations. Six wells on Destin Dome which were shallowerCretaceous tests are not shown in the tables or on figure 14.

In the 1975 Destin Dome drilling, all of the wells were drilled on theflanks of the dome as no leases were sold on top of the structure.This was by far the costliest unsuccessful drilling campaign ever car-ried out on a single structure. Much of the loss was taken by Exxonbecause reliance on the seismic "bright spot" technique causedthem to pay high prices for wildcat acreage. Exxon may recoup theselosses since they bought acreage on top of the structure in the latestlease sale.

At the present time Shell has drilled and abandoned Smackoverand Norphlet wells in Block 160. Exxon drilled and abandoned aSmackover and Norphlet test in Block 284. Chevon is drilling below22,000 feet in Block 422.

In the Desoto Canyon area, which lies just south of the DestinDome area, 27 blocks were acquired by Amoco, Shell, Conoco, Exx-on, Getty and Chevron or combinations of these companies. Prior tothe sale, no leases had been acquired in DeSoto Canyon. In theGainesville, Apalachicola, and Florida Middle Ground areas, (figure14) a total of eight blocks were acquired by Sohio.

In the Gainesville area, Sohio drilled a dry hole in block 707-1. It isbelieved the well penetrated a very thick Eagle Mills section and-'Wasabandoned in Paleozoic rocks at about 16,000 feet.

In the Pensacola area Sohio drilled a Smackover and Norphlet testin block 948-1. Total depth was 18,958 feet. The well was drilled on aLouann Salt anticline.

No new leases were nominated in the Charlotte Harbor area. Drill-ing in this area in the past has been unsuccessful and basementrocks have been found at 10,000 to 12,000 feet in wells which havebeen drilled on a structural feature called the Sarasota Arch (figure


15). This arch extends from Sarasota County southwest to the con-tinental edge.

The Pulley Ridge and Howell Hook areas, which lie within theboundaries of the South Florida Basin (figure 14), had 57 and threeblocks leased, respectively, by Gulf, Superior, Tenneco, Shell, Union,and Texaco, or combinations of these companies. The area most fre-quently nominated for leasing within Pulley Ridge lies to the nor-thwest and northeast of the Dry Tortugas, except for the three blocksin the Howell Hook area (figure 14). This area is of interest becausethe Lower Trinity rocks drilled in the Marquesas Keys (P-275 andP-284, figure 14) had thick zones of vugular porosity in the BrownDolomite Zone of the Twelve Mile Member of the Lehigh Acres For-mation. There are other possible targets, including the SunnilandFormation which is productive onshore, and the older Coahuilan(lowermost Cretaceous and possible Jurassic age rocks). At the pre-sent time there are environmental constraints on drilling in the PulleyRidge and Howell Hook areas. This includes all acreage south of 26degrees north latitude.

The blocks nominated are all located on a large gravity minimum,which is at least 100 miles in length. Oil fields in the Sunniland For-mation in the South Florida Basin have been found associated withgravity minima.

Atlantic Outer Continental Shelf Area

The COST GE-1, a stratigraphic test, was drilled in the UnitedStates South Atlantic Outer Continental Shelf Area about 74 mileseast of Jacksonville, Florida, in 1977. It lies within the SoutheastGeorgia Embayment (figure 15). Six wildcat wells were later drilled inthe general area.

The well penetrated sedimentary strata of Early Cretaceousthrough Quaternary age. Below 11,000 feet, highly indurated to weak-ly metamorphosed shales with meta-igneous rocks were en-countered. Dating of several samples of these metamorphosed ig-neous rocks yielded values about 355 million years before present(Scholle, 1979). The rocks are considered to be Late Devonian in age.From 5,950 to 11,000 feet, Lower Cretaceous rocks which weredominantly continental in character, with very low organic carboncontent and extremely low extractable hydrocarbons were en-countered. Temperatures in these rocks are believed to have been in-sufficient to have generated and expelled hydrocarbons above 8,500feet Between 3,500 and 5,950 feet, Upper Cretaceous rocks whichwere marine in origin were encountered. These rocks, below 3,600feet, had a high content of marine organic matter but were thermallyimmature. The interval above 3,600 feet was thermally immature andhad a very poor source rock potential (Scholle, 1979). The in-


escapable conclusion, drawn from a careful study of thesesediments and borne out by six additional wildcat wells, is that thisarea has an extremely low oil potential.

GEOPHYSICAL EXPLORATION ACTIVITY

Chapter 377, Part 1, Florida Statutes, as amended in 1980,authorized the Department of Natural Resources to regulategeophysical activity. Rules (Chapter 16C-26.07, Florida Ad-ministrative Code) were adopted in 1984 to implement this statute.The intent of the Rules is stated in Rule 16C-26.07 (1), F.A.C., asfollows:

It is the intent of the department to permit geophysical opera-tions in search of naturally occurring oil, gas, or minerals inFlorida provided that this activity is conducted in a mannerwhich minimizes or prevents the destruction of or injury tothe environment and the natural resources of the State ofFlorida. This regulation shall govern any and all geophysicalactivities utilized in the exploration for hydrocarbons, in-cluding seismic, core drilling, or other type exploration work(whether or not involving the discharge of explosives) on or inuplands, wetlands, submerged lands, or in the water columnabove State lands in the State of Florida.

The first applications for geophysical permit3 were received by theDepartment's Bureau of Geology on May 17,1984 (see Appendix VIII).These applications were for a 25-mile and a 13-mile seismic survey,both in Escambia and Santa Rosa counties. These applications wereapproved and given the first two permits on July 6, 1984.

Twenty-nine applications for geophysical permits were processedduring 1984; all of these applications were approved. Twenty-three ofthe permits were for seismic exploration in Escambia and SantaRosa counties; four were for seismic exploration in south Florida inLee, Collier, Charlotte, and Palm Beach counties; the remaining twowere for seismic exploration in north Florida and included areas inJackson, Madison, Hamilton, and Columbia counties. Of these 29permitted surveys, 23 have been completed, five have yet to besurveyed and two were cancelled by the geophysical companies.

Figure 16 shows the areas covered by completed surveys and theareas covered by permitted, but not completed surveys for 1984.Seismic exploration for 1984 was concentrated in Escambia and San-ta Rosa counties. Surveys in these two counties yielded a total of569.5 miles of shot-hole and 51 miles of Vibroseis lines. Remainingnorth Florida exploration in Jackson, Madison, Hamilton, and Colum-bia counties covered 48 miles (Vibroseis). Only one of the southFlorida permitted surveys has been completed.' It included 22 milesof survey lines in Collier County.

Seismic exploration in 1985 is expected to again concentrate inEscambia and Santa Rosa counties. Interest in south Florida may in-crease due to Exxon's continued success at Raccoon Point field. Ifenvironmental and political issues can be successfully resolved, off-shore seismic exploration may also be expected during 1985.

production for the field. Original oil in place calculated by volumetric method(Tootle, Charles, 1978, personal communication).

8. Single well (P-897) is shut-in. No estimates available.9. The sum yields only an order-of-magnitude estimate of original recoverable

oil in place because many of the calculations were done more than six yearsago. In fact, four fields (Blackjack Creek, Mt. Carmel, Mid-Felda, and LakeTrafford) have already produced more than their estimated recoverable oil inplace. Work on updated values is in progress. Statewide cumulative produc-tion as of Jan. 1, 1985, equals 474,842 MBbls. A rough (conservative) estimateof remaining reserves is therefore equal to 567,951-474,842 MBbls or 93,109MBbls.
