Florida Geological Survey 1988 and 1989 ONSHORE DRILLING ACTIVITY Only three development wells were drilled during 1988 and 1989. A description of these wells is given in Appendix 4. One of these was an injection well drilled at Jay field in Santa Rosa County. One was the first offset to the McDavid field discovery well in Escambia County and was plugged and abandoned as a dry hole. The McDavid field discovery and this offset are discussed under the "Florida oil fields descriptions" section of this report. The third development well was completed as a potential producer at Raccoon Point field in Collier County. Sixteen exploratory wells were drilled during 1988 and 1989 (Appendix 5). Eleven of these were drilled in northwest Florida; the remaining five were drilled in south Florida. Only one well was completed as a potential producer. This was the discovery well for McDavid field (Escambia County). Coldwater Creek field was also discovered in 1988 with the first production test of the Red Rock Oil and Minerals Corporation Pittman Estate No. 26-2A in Santa Rosa County. Further discussion of this field is in the "Florida oil field descriptions" section of this report. OFFSHORE DRILLING ACTIVITY State ownership of the continental shelf off Florida extends three miles into the Atlantic Ocean and about 10.5 miles (three marine leagues) into the Gulf of Mexico. The federal government controls resources beyond these state boundaries out to 200 miles. The Outer Continental Shelf (OCS) is a jurisdictional term that describes the offshore area which is under control of the federal government. "Federal waters," in this context, does not refer to ownership, but rather to responsibility (Johnson and Tucker, 1987). Exploratory Drilling in State Waters A total of 19 wells have been drilled in Florida state waters from 1947 through 1983 (Appendix 6 and Figure 7). Effective July, 1990, all drilling activity was prohibited in Florida state waters (details are discussed in Part II of this publication); however, the information obtained from the wells that were drilled in state waters may be useful in future decisions concerning offshore exploration and development in federal waters. The 19 offshore wells tested three different potential oil horizons. Ten of the wells are within the South Florida Basin (off Charlotte and Lee Counties and off the Florida Keys, Monroe County, Figure 8) and targeted the Lower Cretaceous. The six wells drilled off the Florida panhandle sought to extend the onshore (and offshore Alabama) Jurassic production (Figure 4). The remaining three wells drilled off the northern portion of the Gulf coast (Permits 304, 382 and 383) were Cretaceous or possibly Paleozoic tests (Applegate and Lloyd, 1985). As shown in Appendix 6, only one of the wells drilled in state waters had a significant oil show. A drill stem test of the Gulf Oil-Florida State Lease 826-Y (permit 275), located near the Marquesas Keys off Monroe County, recovered 15 barrels of 220 A.P.I. gravity oil and 14.1 barrels of saltwater from the Lake Trafford (?) Formation. Another well, which was drilled in federal waters near the Marquesas, tested black saltwater in the Lake Trafford and Sunniland Formations and in the Brown Dolomite interval (Applegate and Lloyd, 1985). Charles Tootle (1985, Florida Geological Survey, personal communication, in Applegate and Lloyd, 1985) believed this well could be a low volume oil producer from the Lake Trafford and Sunniland Formations. Applegate (1987) conducted an extensive study of the Brown Dolomite Zone of the Lehigh Acres Formation in the South Florida Basin. He concluded that this zone could be a potentially prolific producing horizon offshore. He found that
