Governor Lawton Chiles, ChairmanFlorida Department of Natural ResourcesTallahassee, Florida 32301

Dear Governor Chiles:

The Florida Geological Survey, Division of Resource Management, Department of Natural Resources,is publishing three petroleum-related reports as its Information Circular 107. Part I is "1988 and 1989Florida Petroleum Production and Exploration;" Part II, "Petroleum Exploration and Development Policiesin Florida: Response to Public Concern for Sensitive Environments;" and Part III: "Petrology andProvenance of the Norphlet Formation, Panhandle, Florida." These reports discuss 1988 and 1989 oiland gas production and exploration, the history of Florida's petroleum policy and legislation, and thegeology of the gas-producing Norphlet Formation, respectively. This information is useful to the oil andgas industry and to the state in planning wise development of Florida's oil and gas resources.

Respectfully yours,

Walter Schmidt, Ph.D., P.G.State Geologist and ChiefFlorida Geological Survey

ABSTRACT

Florida oil production began to decline in 1979 and continued to do so during 1988 and 1989. Jayfield, as the leading producing field for Florida, controls the rate of decline.

Onshore exploratory drilling during 1988 and 1989 resulted in the discovery of McDavid field inEscambia County and Coldwater Creek field in Santa Rosa County. Offshore exploratory drillingincluded six wells which were completed in federal waters off Florida during 1988 and 1989; one of thesewas the second Norphlet discovery in the Destin Dome area and was classified by the federalgovernment as a producible field.

Geophysical exploration during 1988 and 1989 concentrated in the Florida panhandle and the southFlorida peninsula. The panhandle exploration included the known oil-producing Santa Rosa andEscambia Counties, an area offshore from Santa Rosa and Escambia Counties, and the ApalachicolaEmbayment area. South Florida seismic activity was east of the known Sunniland-producing trend inBroward, Dade, Hendry and Palm Beach Counties.

In addition to 1988 and 1989 data, a summary of offshore exploratory drilling in state waters, from 1947through 1983, is included in this report. This information may be useful in evaluating future offshore andonshore development and exploration. Of similar value are descriptions of each of Florida's 22 oil fields.Descriptions include discovery data, geologic information, and production totals.

the Gulf Oil - State of Florida number 1 well producer and was the discovery well for McDavid(permit 182), was completed in 1954. The well is field (Escambia County). Coldwater Creek fieldlocated about three and one-quarter miles east of was also discovered in 1988 with the firstthe discovery well (Figure 1). It was completed production test of the Red Rock Oil and Mineralsas a pumping well in the -11,309 to -11,316 foot Corporation - Pittman Estate No. 26-2A in SantaMSL interval of the Sunniland Formation. Initial Rosa County.production was 112 barrels of 21.70 A.P.I. gravity Six wells were completed in federal waters offoil per day. Water production was not tabulated. Florida during 1988 and 1989. Three of the wells

The distance between the two wells were in the Pensacola area; three were in thecomprising Forty Mile Bend field indicate that Destin Dome area. The principal drilling targetsthey probably did not produce from the same in these areas are the Smackover Formation andreservoir. Mitchell-Tapping (1985) studied the the Norphlet Sandstone (Figure 4). One of thefauna and lithology of Sunniland, Bear Island, Destin Dome area wells (Chevron-6406) is theand Forty Mile Bend fields. His description of the second offshore Norphlet discovery in this area.depositional environment for these fields is Geophysical exploration during 1988 and 1989discussed above in the Sunniland field concentrated in the Florida panhandle and thedescription. He found the lithology and fauna at south Florida peninsula. The panhandleForty Mile Bend to be similar to that of Sunniland exploration included the known oil-producingfield, except for the presence of anhydrite in the Santa Rosa and Escambia Counties, an areapore space and an increase in the dolomite offshore from Santa Rosa and Escambiacontent.

Low oil gravity and low porosity and area. South Florida seismic activity was east ofpermeability in the Sunniland at both well the known Sunniland producing trend in Broward,locations made this field non-commercial. In Dade, Hendry and Palm Beach Counties.addition, a half-inch hole was found in the casingof the Gulf well (permit 182) at -10,027 feet MSL.This could have caused excessive water flow,and thus shortened the productive life of thiswell. Both of the Forty Mile Bend wells wereabandoned in 1956, after producing only 32,888barrels of oil in about 17 months in 1954 and1955 (Appendix 2) (Gunter, 1955 and 1956).

SUMMARY

Florida oil production continued to declineduring 1988 and 1989. Jay field, as the leadingproducing field for Florida, controls the rate ofdecline. The field appears to be following theproduction curve predicted by Christian, et al.(1981) in their discussion of tertiary recoveryestimates for Jay field.

Three development wells and sixteenexploratory wells were drilled during 1988 and1989. One exploratory well was completed as a
