Mississippi was the most active of the southeastern states during 1960; 700 wells were drilled, an increase of 6.5% over the previous year. Nineteen oil fields and 3 gas fields were discovered in the state. The productive zones in the new fields are classified as follows: Tertiary (4 Wilcox oil fields), Upper Cretaceous (1 Selma chalk oil field, 1 Eutaw oil field, and 9 lower Tuscaloosa oil fields), Lower Cretaceous (2 Rodessa oil fields, 1 Hosston oil field, 1 Washita-Fredericksburg gas field, and 1 Paluxy gas field), Paleozoic (2 Mississippian fields). There were 19 new-pool discoveries an 13 field extensions during 1960, The most active field development was seen at McComb in Pike County, where 133 oil wells were completed.

Of the 49 wells drilled in Alabama, 33 were development wells in the Citronelle field.

Four deep unsuccessful Lower Cretaceous wildcat wells were drilled in Florida. One was in the extreme northwestern part of the state; 1 was 6 miles west of the Sunniland field, in the southern part of the peninsula, and 2 were offshore in the shallow waters of the Gulf of Mexico.
