l6 FLORIDA GEOLOGICx\L SURVEY I3TH ANNUAL REPORT 



can not be placed on the importance of saving samples of the drill- 

 ings from all the deep wells that are drilled for whatever purpose. 

 These should be carefuljy collected at frequent intervals regard- 

 less of whether there is a change in the formation or not a,nd 

 properly labeled as to the depth from which they were taken. 



Of interest in consideration of the subject of oil in Florida 

 is a Press Bulletin of the United States Geological Survey which 

 appeared during April 1920. This bulletin relates to Peninsular 

 Florida, in fact that portion of the State lying from Suwannee 

 County eastward. The title as first published is misleading in 

 that it includes the entire State but from the subject matter it is 

 readily seen that the area lying from Suwannee County westward 

 is not treated. The bulletin referred to is herewith republished 

 with the insertion of the word "Peninsular" in the title: 



DRILLING FOR OIL IN PENINSULAR FLORIDA. 



ADVICE GIVEN BY GOVERNMENT GEOLOGIST. 



Wells have been drilled for oil in every State in the Union ex- 

 cept the New England States and possibly four others — North 

 Carolina, South Carolina, Nevada, and Idaho. Only sixteen states, 

 however, can be called oil-producing. A number of deep wells 

 have been drilled in Florida, the deepest being one near Bush- 

 nell, in Sumter County, which was carried to a depth of 3,080 feet. 

 This well and one near Waycross, in southern Georgia, which 

 was drilled to a depth of 3,045 feet, are two of the deepest wells 

 in the Atlantic Coastal Plain. 



GEOLOGISTS NOT HOPEFUL OF SUCCESS. 



Although the deep wells drilled in Florida have yielded no 

 indications of oil the interest in the possibility of finding oil there 

 has not been diminished by their failure but has actually increased 

 with the increase in the prosperity of the State, so that much 

 money has been spent in drilling test wells in areas where oil 

 is not likely to be found. As additional wells will no doubt be 

 drilled in Florida the results of geologic field work done by O.
