FLORIDA'S OIL AND GAS RESERVES FOR 1991


By
Charles H. Tootle, Ph.D., P.E. #40500

DISCLAIMER: AN ATTEMPT WAS MADE TO PRESENT A REALISTIC INTERPRETATION OF THESE

DATA; HOWEVER, NO GUARANTEE OR WARRANTY IS EXPRESSED NOR IMPLIED; AND ANYONE WHO

USES THIS INFORMATION, DOES SO AT HIS OWN RISK.

Oil was discovered in Florida on September 22, 1943, with the completion
of the Gulf Coast Realties Corporation Well No. 1 (Permit 42) in the southeast

quarter of Section 29, Township 48 South, Range 30 East in Collier County. This

well was drilled to a total depth of 11,626 feet, and it was completed with an

open hole from 11,602 feet to 11,626 feet in the carbonate, Sunniland Formation

of Lower Cretaceous Age. This well discovered the Sunniland Oil Field with
37,685,118 barrels of oil originally in place. The original recoverable oil in

place was 18,842,559 barrels, and 18,444,812 barrels of oil had been produced

from this field as of January 1, 1991. Original recoverable gas in place was

1,884,256 MCF, and 1,824,628 MCF of gas had been produced from this field as of

January 1, 1991.
Twenty-one additional oil fields, which are shown in Figure 1, have been

discovered in Florida, as of January 1, 1991. The original oil in place was

1,203,618,403 barrels, and the original recoverable oil in place was 634,111,643
barrels. As of January 1, 1991, a total of 524,790,066 barrels of oil and

539,313,256 MCF of gas have been produced from Florida's twenty-two oil fields.

This leaves 109,321,577 barrels of oil and 118,289,689 MCF of gas which can be

produced with today's technology and economic conditions. There is a paucity of

oil reserve data for Florida. The author's reconnaissance oil reserve survey,

which was typed in March, 1978, but not published, because of economic

conditions, was the first and only oil reserve data for Florida, other than the

Operator's Data, which was considered to be highly proprietary. This Open File

Report No. 44 is an up-date to the March, 1978, Oil Reserve Survey, and the

"Information Circular No. 107".

Archie's equation was used to estimate the oil saturations in two feet

increments. The formation water resistivities used were 0.018 ohm-meters for the
Smackover and 0.022 ohm-meters for the Sunniland. Formation temperatures were

estimated with the formulae SST = 76 + Depth/80 for the panhandle, and by SST=

76 + Depth/100 for Peninsula Florida. SST is the sub-surface formation

temperature in degrees Fahrenheit, and the depth is the distance in feet below

the ground's surface.
The volumetric calculation procedure was utilized to estimate the reserves

for all of the oil fields except the Sunniland, Sunoco Felda, and West Felda

Fields. Decline curve analysis was utilized to estimate the reserves for these

three oil fields, because they are rather old fields, and they are well into the

decline part of their production curves, which gives more creditable results,

than in the case of younger fields. Few porosity logs were available for these

three oil fields, and most of the wells were drilled with water, which made the

resistivity logs yield anomalous values; so, decline curve analysis was utilized

for the Sunniland, Sunoco Felda, and West Felda Field Reserves, which are listed

in Tables 3 and 4. Discovery well data are listed in Tables 1 and 2, and annual

production data for Florida's Oil and Gas are shown in Figure 2. The Forty Mile

Bend, Seminole, Sweetwater Creek, and Baxter Island Fields have been plugged and

abandoned, but they have been included for complete coverage and information.
