OIL AND GAS ACTIVITIES IN FLORIDA, 1970by Clarence Babcock

In 1970 a major Smackover discovery was made in the Florida panhandle.Also, a new field was discovered in the southern part of the State. Inaddition, the daily oil production from the West Sunoco-Felda field ofsouthern Florida increased from 980 barrels from five wells during December,1969 to 7,470 barrels from 17 wells during the corresponding month a yearlater. Developments in 1970 were more significant than all previous develop-ments in the history of the oil and gas in Florida.

Specific descriptions of the new discovery wells, and the recent develop-ment wells in the West Sunoco-Felda field, will be highlighted in this report.

EXPLORATORY DRILLING

As summarized in exploratory footage table 1, a total of 182,978 feet wasdrilled in wells completed in 1970. This footage was drilled in two discoverywells, one presumably successful outpost well, and 12 wildcat tests whichwere plugged and abandoned. The locations of the tabulated wells are shownon figure 1; and data sheets for each well listed are presented in appendix 1.

Exploratory footage table 1, discussed above, as well as developmentfootage table 2, which is discussed later in the report, list only those wellswhich were completed in 1970; permit numbers corresponding to thesecompleted wells also are shown. The readership may desire to effect areconciliation, as of December 31, 1970, of permit numbers for completedwells (tables 1 and 2) and uncompleted wells. To facilitate such areconciliation, a categorical list of the permit numbers corresponding touncompleted wells is shown in appendix 2.

The two 1970 discovery wells listed in table 1 will be discussed.

THE STATE'S MAJOR SMACKOVER DISCOVERY,NORTHWESTERN FLORIDA

The Humble Oil and Refining Company and the Louisiana Land andExploration Company established excellent Jurassic-Smackover oil productionat their No. 1 St. Regis Paper Company, et al well, Section 43-5N 29W, Jayarea, Santa Rosa County, northwestern Florida.

On a six-hour Initial Production Test through perforations at 15,470-524feet this discovery flowed natural at a rate of 1,712 barrels of 50.7 degreegravity oil plus 2.15 million cubic feet of gas per day through ¼-inch choke.The gas contained 10.6 percent H2S. Tubing pressure was 3,450 pounds, andgas-oil ratio was 1,253 to 1. Following testing operations the well was shut inon June 11, 1970.

This well is considered to be one of the best Smackover discoveries in thesoutheast during the past ten years. It also is the first well to penetrate theSmackover Formation of the upper Jurassic section of northwestern Florida.It is 5% miles southeast of the Humble, No. 1 Loper producer, located on thesouthern flank of the Flomaton gas field, Escambia County, Alabama, whichwas discovered in 1968. The Loper well flowed through perforations at15,414434 feet in the Norphlet Formation at a rate of 350 barrels ofcondensate plus 4.6 million cubic feet of gas per day.

Ownership in the jointly-operated oil production unit containing some3,000 acres located over much of the most productive part of the Jaystructure is:

PercentHumble Oil and Refining Company 35.4Louisiana Land and Exploration Company 38.5Sun Oil Company 14.5Others 11.5

The operators have installed a small separator plant to extract the sulphurcontent from the production at Jay. This plant has a capacity of 2,000 BOPD.The operators plan to complete a 12,000-BOPD separator plant in the lastquarter of 1971. It is anticipated that the capacity of this plant will beincreased and/or additional plants will be built to handle further increases inproduction at Jay.

Leasing activity throughout Santa Rosa County, Escambia County andOkaloosa County, and in the southern part of the remaining counties ofnorthwestern Florida, has been very heavy and competitive.

THE JAY STRUCTURE

Figure 2 depicts the Jay structure on which the discovery well at Jay islocated.

The Jay structure appears to be similar in structural type, influence onoverlying sediments, and position within the basin, to the Quitman field,Clarke County, Mississippi, as that field is depicted by Hughes (1968, fig. 2).Hughes designates the Quitman field as a low relief peripheral salt ridge; hisexplanation (p. 322) of the origin of this type of structure is:

"The origin of the peripheral salt ridge and its associated peripheralsalt belt is explained by simple salt movement contemporaneous withdeposition. The salt was deposited as a wedge with gradual thickening tothe south from its updip limit. As the basin floor tilted southward, thewedgeout edge of the salt became the highest portion of the sale mass.Overburden was deposited contemporaneous with tilting to create

differential forces which caused the salt to flow toward the wedgeout.This produced the salt ridge immediately south of the wedgeout."

Hughes did not imply wrenching action by his contours of the Quitman field(ibid, fig. 6, p. 328).

An abstract of a paper by Keyes (1971, p. 347) relative to the area of theFlomaton field, located some five to eight miles northwest of the discoverywell at Jay, states that:

"Movement of Louann salt and faulting occurred, probably as a resultof gravity slide and basinward salt creep, (which formed) structurescapable of trapping hydrocarbons."

This statement is believed to be appropriate as an explanation of the Jaystructure as well as of the structure which traps the hydrocarbons atFlomaton.

A specific explanation for the reversal and assymetrical configuration of theJay structure must await well control and the preparation is isopach mapstherefrom. Mechanisms which may prove to be involved include: a) saltflowage, presumably up regional dip, "toward the wedgeout," as discussed byHughes (ibid.), b) the "rollover", of the beds of the downthrown block intothe fault plane as a result of a flattening of the dip of the fault plane withdepth, c) the "rollover" of the beds of the downthrown block into the faultplane when underlying salt becomes detached from the upthrown block andslips under the overburden, d) the draping of overlying beds over areas fromwhich salt was dissolved in connection with a separation at the salt levelresulting from the down-to-the-coast Foshee fault.

The Fochee fault is assumed to be a "pull-apart" fault which developedafter the coastward component of the overburden pressure became sufficientto cause the plastic flow of the salt. Hughes (1968, p. 330) states that inClarke County, Mississippi:

"Salt flowage began soon after deposition of a small amount ofoverburden. In the area studied salt flowage began after only a fewhundred feet of Norphlet was deposited on top of the Louann salt."

The Foshee fault trace at the approximate level of the Bucatunna ClayMember of the Byram Formation is depicted by Marsh (1962, plate 1; andalso 1966, fig. 24, p. 97). The 1962 report shows that in the Jay area theBucatunna occurs from about 300 to 500 feet of depth sub-sea. The 1966report shows the fault trace to be probably angular, and to be about 26 mileslong. It also shows that three antithetical faults are associated primarily orexclusively with the northerly part of this fault plane. It seems reasonable thatat the Smackover level the engagement of the northerly part of the faultplane, which probably had dip slip movement, with the southerly part of theplane, with probable strike slip movement in part, may have resulted in atleast slight wrenching action.

6 BUREAU OF GEOLOGY

Coincidence of the Foshee fault with a zone of weakness in rocksunderlying the Louann salt would strengthen the possibility that a wrenchingmovement was involved in the formation of the Jay structure.

It is quite possible that other oil accumulations in traps of the Jay typeoccur in Florida parallel to the Foshee fault. Also, traps in northwesternFlorida, and especially south of Jay, may exist in other types of saltstructures. The type and size of salt structures in Clarke County, Mississippiare controlled by the thickness of the mother salt (Hughes, 1968, p. 321). Itis anticipated that the salt thickness likewise will determine the characteristicsof salt structures in the northwestern part of Florida. And areas or bands ofsimilar salt thickness are likely to be oriented at least roughly parallel to thestrike of contours on top of a high resistivity marker in the Eutaw Formationof the Upper Cretaceous section (Puri and Vernon, fig. 10, p. 30).

HUMBLE, NO. 1 LEHIGH ACRES DEVELOPMENT, INC.DISCOVERY WELL

The Lehigh Acres discovery well, Section 14-45S-27E, Lee County,southern Florida, was completed June 8, 1970. On Initial Pumping Productiontest through perforations in the upper Sunniland Limestone at 11,472-482feet this well yielded 508 BOPD (barrels of oil per day) plus 20 BWPD(barrels of water per day); oil gravity was 27 degrees.

The Lehigh Acres area (figs. 1 and 3) is being developed with a 160-acrespacing pattern. Development plans call for the drilling of several directionalholes from each of a limited number of surface pads, in deference to LehighAcres Properties, which wishes to minimize damage to esthetic values.

DESCRIPTIONSOF PRE-1970 FIELDS

SUNNILAND FIELD

The structural trap for this field (fig. 1), discovered in 1943 and operatedby the Humble Oil and Refining Company, is a northwest-southeast dome 2miles wide and 4 % miles long. There are 17 producing wells on this structure.

Production is from calcareous rock containing disoriented macro-fossils(rudistids), which is reached at a depth of about 11,500 feet. This productionis obtained from five zones or porosity occurring within an interval beginningat the top of the Sunniland Limestone and extending to a point about 60 feetlower in the section. The intervals of hard calcilutite separating the five zonesvary from 3 to 10 feet in thickness (unpublished cross sections prepared byWoodson R. Oglesby, Bureau of Geology). The lowermost of the fiveproductive zones, known as D zone, has a bottom-water drive, whereas thefour overlying zones have side-water drives.

The yield of the better wells in the field ranges from about 188 to 390BOPD.

At this time it is thought that 35 million barrels of oil probably is areasonable figure for the initially recoverable reserves of the field. Somereports state that the gravity of the oil in specified field wells is as low as 19degrees; other reports quote figures as high as 26 degrees.

In 1969 submersible pumps were installed in some of the wells in theSunniland field to increase oil production. These pumps have not caused anincrease in the percentage of salt water production from this field (table 3).

SUNOCO-FELDA FIELD

In 1964 the Sun Oil Company discovered the Sunoco-Felda field (figs. 1and 3), located 18 miles north of the Sunniland field.

The Sunoco-Felda field contains 22 producing wells drilled on 160-acrespacing; the limits of the field to the north, south and east are defined bynine dry offset field wells, and three outpost wells. The production from thebetter wells in the field ranges from about 160 to 240 BOPD.

Structural nosing associated with a decrease of oil permeability inup-gradient directions where the section is relatively chalky is the trappingmechanism in the Sunoco-Felda field.

This field produces from the upper part of the miliolilic Roberts zone, thename used by the operator. State Board of Conservation Order No. 1,December 15, 1964, designating this zone as the Roberts pool, described it inthe Sun Oil Company, No. 1 Red Cattle Company well, Section 30-45S-29E,Hendry County, as occupying the interval from 11,420 to 11,570 feet. This150 foot interval comprises the upper part of the Sunniland Limestone, whichis 190 feet thick in the No. 1 Red Cattle Company well. The SunnilandLimestone is part of the Glen Rose Subgroup of the Lower Cretaceous TrinityGroup. This formation is described by Paul L. Applin (1960, p. 209-211).

The No. 1 Red Cattle Company well was perforated at 11,482-11,484½feet; this is a part of the stratigraphic interval which produces throughout theSunoco-Felda field. The top of these perforations are 62% feet below the topof the Roberts zone; this perforated interval appears to be the correlative ofthe D zone in the Humble Oil and Refining Company, No. 26 Gulf Coast


Realties Corporation well of the Sunniland field. The subject productiveinterval has a bottom water drive in both fields.

WEST SUNOCO-FELDA FIELD

The Sun Oil Company drilled the discovery well for the West Sunoco-Felda

field (figs. 1 and 3) in 1966 at a location 3 miles west of the Sunoco-Felda

field. State Board of Conservation Order No. 8, August 29, 1969, formally

recognized that there is no connection between the oil accumulation in the

West-Sunoco-Felda field, and that in the original Sunoco-Felda field, exceptthat of the common water drive of the area.

In the West Sunoco-Felda field oil is trapped in a local anticlinal featurewhich has at least 60 feet of vertical relief. Oil permeability in miliolitic rockwas developed in an interval acted upon by relatively high wave energy alongthe shore-line. In the West Sunoco-Felda field oil permeability is less desirable

in parts of the field where the productive rock is relatively chalky.In the West Sunoco-Felda field the productive interval in the first three

producers was the porous interval of the Roberts zone which produces in the

Sunoco-Felda field; this is the stratigraphic equivalent of the D zone of the

Sunniland field. The combined oil yield of the Initial Pumping ProductionTests on these three wells was 243 BOPD; the per well average was 81 BOPD.

The fourteen subsequent producers in the West Sunoco-Felda field are

perforated in the C interval, which is the approximate stratigraphic equivalent

of the C zone of the Sunniland field. The C interval overlies, with little or no

separation, the well-stained Roberts zone porosity of the Sunoco-Felda field

(Babcock, 1970, fig. 4). The combined oil yield on Initial Production Tests ofthese fourteen wells was 9,135 BOPD; the per well average was 653 BOPD.

Figure 4 shows the oil-water contact in the West Sunoco-Felda field. This

figure also indicates the amount by which the water must rise to reach thetop of perforations in field wells.

So far two dry holes and an abandoned producer have defined only the

northeast and southeast limits of the field.

MOBIL'S NEW FIELDAT LAKE TRAFFORD

The Barron Collier, Jr., discovery well is so far the only well in Mobil's

new field at Lake Trafford (fig. 1). This well is located in Section 9-47S-28E,Collier County, southern Florida, and about 1% miles southwest of LakeTrafford. It was completed on March 30, 1968 with an Initial PumpingProduction of 118 BOPD and 78 BWPD through perforation at 11,870-892feet. Subsequently, the well was re-cemented and re-perforated, and it

currently produces approximately 100 BOPD with no water. The top of the

productive interval, which occurs in the lower part of the SunnilandLimestone, is about 15 feet above the Punta Gorda Anhydrite. The other

The rock from which production is obtained in the Mobil well consists ofhard calcilutite. It is understood that permeability in this rock was developedby boring organisms on a mud flat.

PRODUCTION, 1970

Almost all of the State's 1970 oil production is from the five fields ofsouthern Florida, all of which operate on pump. The 1970 monthlyproduction by field for this part of the State, and the cumulated productionof the fields as of December 31, 1970, is included in tables 4 and 5. Asummation of this information for the five fields of southern Florida is:

In addition, table 6 shows that a total of 6,819 barrels of oil flowed fromthe discovery well of the Jay field of northwestern Florida in 1970.

Data sheets for each well listed in production tables 4, 5 and 6 arepresented in appendix 1.

AVERAGE PRICES AT WELL HEADOF SOUTHERN FLORIDA CRUDE OIL, 1970

The average prices at the well head received in 1970 for southern Floridacrude oil are presented in table 7. These prices varied from $2.15 to $3.15.

ANTICIPATED INCREASEIN PRODUCTION

In view of the new discoveries in Florida in recent years, and especially in1970, an estimate of percent of production increase or decrease within thenext ten years is pertinent. Tables 4, 5 and 6, which present the production


figure for the past three years, are considered in arriving at this estimate.In making this estimate two assumptions are made which appear feasible,

but which do not reflect any information received by the State from theoperators. These assumptions are: 1)that a 12,000-BOPD increment inseparator plant capacity will be completed each October, 1971-1975, inclusive,and 2) that an average of 2 rigs, each requiring 2 months per well, will drillthrough September, 1974 when 48 field wells should be completed.

Other factors considered in the estimate include: the size of the Jaystructure as indicated by available subsurface control (fig. 2), the probableallowable of its wells (1,000 BOPD), and the fact that it appears quite certainthat the field will be developed with a 160-acre spacing pattern.

On the basis of the foregoing considerations, table 8 shows the anticipatedincrease in oil production, from the fields discovered as of December 31,1970, for each year of the next ten years. Also, this table shows that in 1980the oil production in Florida from fields already discovered will be about 7%times the current production. A review of table 8 indicates that the 1980 levelof production will have been reached, approximately, as early as 1974.

As a matter of interest, the present oil production is 8% times theproduction in 1960 (353,703 barrels).

It appears probable that in the coming decade new discoveries will be madein both the northwestern part of the State, and in southern Florida. Table 8shows that it is anticipated that by 1974 about 73 percent of Florida's oilproduction will be derived from the Jay field. Obviously, each additionaldiscovery as good or better than Jay will result in a notable increase in theproduction of the State.

The Mineral Industry Survey, U.S. Department of the Interior, Bureau ofMines, October 23, 1970, estimated that the actual crude oil demand forNovember, 1969 would be:

Daily Relative National

For State Of Barrels Position

Mississippi 177,000 10th

Alabama 18,000 21st

According to these statistics Mississippi is about 10 times more important asan oil producing state than is Alabama. Also, since Florida's production in1970 was about 8,500 BOPD, it appears that doubling this State's oilproduction could almost raise it to the level of Alabama as a producer.

Table 9 shows that the approximate gas production in 1970 from Florida'ssix fields was 307.8 million cubic feet; also, the anticipated gas production in1980 from the six fields already discovered is 22,372 million cubic feet. Fromthese figures it is estimated that the gas production in 1980 from alreadydiscovered fields will be about 73 times the 1970 production (22,372 mm cf- 307.8 mm cf). Since much of this production will contain H2 S gas, some ofwhich will be transported across State boundary lines, it appears that theFederal Government will be involved in pipeline specifications and regulations.


RIGS OPERATING IN FLORIDA

Ten rigs were used in the drilling of 29 wells completed in 1970 (table 10).

GEOPHYSICAL ACTIVITY

OFFSHORE GEOPHYSICS

The 1970 Florida offshore geophysical permits, consisting entirely ofpermits for seismic activity, are summarized in table 11; locations of thepermits are shown on figure 5. These presentations show that in 1970 therewere 11 permits for offshore geophysical activity. Ten of these permits werefor work performed on State and Federal water bottoms west and south ofFlorida; and one permit was for a survey of Federal acreage offshore from theFlorida east coast.

The number of Florida offshore permits for each of the previous sevenyears has been 5 in 1963, 7 in 1964, 10 in 1965, 13 in 1966, 23 in 1967, 19in 1968, and 9 in 1969.

Details of Florida's mainland geophysical activity, 1970, which totaled 293crew weeks, are presented in table 12; it appears that most, and possibly all,of this work consisted of seismic surveying. For comparison, the 1969 figurefor geophysical activity was 236 crew weeks.

Table 13 recapitulates the 1970 geophysical activity by regional areaswithin the State. This table shows that 247% crew weeks of work (91 percentof the total) occurred in northwestern Florida. This mostly reflects theinterest in the Smackover prospects of this area. A total of 35% crew weeksof geophysics (12 percent) occurred in southern Florida.

LAND

OFFSHORE ACREAGE

Figure 6 shows the locations, and a tabulation of lease information, forFlorida's two current offshore leases. The mineral rights of both of theseleases, containing a combined total of 3,910,460 acres, are held by the CoastalPetroleum Company, and the annual rental received by the State from theleases is $49,614.40.

Also, Coastal holds State Mineral Lease No. 248 on 11 lake bottoms ofFlorida containing a combined total of 660,736 acres, including LakeOkeechobee, with 467,200 acres. The annual rental on this lease is$19,985.92.

In 1964 the Coastal Petroleum Company entered into a farmout agreementwith the Mobil Oil Corporation relative to the company's three water bottom

leases of State acreage. Under the terms of this agreement Mobil may earn aone-half interest in the oil and gas rights under these leases by the assumptionof certain obligations. With respect to minerals other than oil and gas andincluding limestone, Mobil can earn such an interest only as to areas one milefrom the shore on Lease Nos. 224A and 224B.

In a Federal Court case which commenced October 20, 1969 and lastedthree days, Coastal brought suit against the U.S. Corps of Engineers, theTrustees of the Internal Improvement Fund, and the Central and SouthernFlorida Flood Control District. Coastal maintained that the defendants hadillegally denied the company the right to mine limerock from LakeOkeechobee under the terms of its lease. As of December 31, 1970 FederalCourt proceedings had not reached a point of final conclusion relative to someof the significant facets of the case, despite the fact that an opinion had beenrendered.

Coastal's obligations with respect to its Florida leases were suspended byFederal Court action in October, 1969 pending the outcome of the abovelitigation. A suspension has been granted by Coastal to Mobil with respect tothe latter's obligations under the 1964 farmout agreement between the twocompanies.

MAINLAND ACREAGE

Current figures on acreage under lease on the Florida mainland are notavailable to this office. In 1966, however, those figures totalled 3,754,136acres.

NEW FLORIDA STATUTESAFFECTING MINERALS

There were no Hearings before the Florida Department of NaturalResources during 1970, nor were any new rules and regulations promulgatedin this period.

There were, however, several Florida statutes enacted in 1970 which affectminerals, which are:

1) Chapter 193.481 Assessment of oil, mineral and other subsurfacerights.

This chapter provides that the subsurface owner of separately-ownedmineral deeds shall pay ad valorem property taxes for this ownership asassessed at a just valuation. Further, tax certificates which encumbersubsurface rights may be negotiated just as in real property; inparticular, the owner of the fee title can purchase these certificates.However, this law does not effect any contractual obligations existing onJune 4, 1969.

2) Chapter 197.063 Delinquent taxes on subsurface rights; notice ofsale; rights of fee owner.

This statute provides for notification of the fee owner if thecertificates for subsurface mineral deeds are to be sold for taxes, so thathe may purchase these certificates at the maximum rate of interestprovided by law before bids are accepted for sale of the certificates.

3) Chapter 704.05 Easements and Rights of Entry.This chapter specifies that easements given or reserved in connection

with any conveyance or devise of realty for purposes of exploration ordevelopment can be cancelled after expiration of 20 years from date ofrecord if non-exercise of right to explore or develop can be proven.

On December 10, 1970 Senator David H. McClain prefiled Senate Bill210 which, if enacted into law in the 1971 Legislative Session, willrepeal Chapter 704.05.An important effect of the three chapters discussed above would be to

prevent wide dispersal of title such as has occurred in other states. Chapter704.05 Easements and Rights of Entry, in particular, seems to be especiallysimilar in intent to the proscription law of Louisiana.
