FLORIDA GEOLOGICAL SURVEY—I4TH ANNUAL REPORT 
ida East Coast Oil, Gas and Mineral Co. began a test 2>y 2 miles south of 
Melbourne in Brevard County. This was drilled to a depth of about 
1,000 feet, at which depth it was abandoned. Well No. 2 was started and 
has a depth of 115 feet. Near Greensboro, Gadsden County, a well was 
bored in 1917 which reached a depth of about 1,750 feet. Salt water is 
reported at about 1,300 feet. (See Gadsden County.) In 1918 the 
Dundee Petroleum Company completed a well a few miles south of 
Sumterville in Sumter County. This has a depth of 3,090 feet and is 
the deepest test so far drilled in peninsular Florida. A descriptive log 
of this well will be found later in this report. (See Ocala Area.) In 
1918 a deep well was begun near the west bank of the Withlacoochee 
River, about five miles east of Dade City. This is reported to have a 
depth of 2,200 feet and to have flowed strong sulphur water at about 
2,000 feet.* In October, 1919, the Calhoun Gas and Oil Company 
began their test near Clarksville, northern Calhoun County. This was 
abandoned in 1920 at the depth of 1,320 feet. Samples of the drillings 
were saved and a descriptive log will be found under notes on Calhoun 
County. During 1920 two wells were begun in Walton County, one 
about seven miles west of DeFuniak Springs at a locality known as 
Rat Head, and the other about twenty-five miles southeast of DeFuniak 
Springs, near Bruce. These tests have a reported depth of 1,888 feet 
and 770 feet, respectively. (For logs see Walton County.) During 
1920 and 1921 a very careful test to 4,912 feet was made by the Chipley 
Oil Company about four miles south of Chipley, Washington County. 
This is the deepest well so far drilled in Florida. 
A few tests are in progress at the present time, among which are: 
Central Florida Oil and Gas Company, about ten miles southeast of 
Tallahassee, Leon County, which was begun in March, 1921; the well 
by Mr. Rollin V. Hill, near Oldsmar, Pinellas County, begun Novem¬ 
ber 24, 1921, and the test by the Florida Petroleum Syndicate, about 
twelve miles southeast of Ft. Myers, Tee County, which was begun 
March 30, 1922. 
This report includes first an introductory statement as to the nature 
of petroleum and the conditions under which it occurs, followed by a 
discussion of the geology of Florida and of the conditions prevailing in 
*From Mr. J. M. Critchlow, Lake Alfred, Florida, owner of the well. Conver¬ 
sation of February 15, 1922.
