Lower Tuscaloosa of southern Mississippi
The Lower Tuscaloosa Formation of the upper Cretaceous currently is producing primarily oil from more than 50 fields in the interior salt basin of Mississippi. These fields are located within an area extending from east Louisiana into SW and S.-central Mississippi (Jefferson, Adams, Franklin, Lincoln, Amite, Pike, Walthall, Lamar, Forrest, and Pearl River Counties). Stratigraphically, the Lower Tuscaloosa unconformably overlies lower Cretaceous sediments of the Dantzler Formation and underlies lower Cretaceous shales of the Middle Tuscaloosa. The formation consists of a transgressive sequence that grades upward from alluvial plain through delta to marine deposits. Prospecting for oil and gas as well as developing new fields in the Lower Tuscaloosa can be difficult. There is generally a lack of strong structural closure; accumulation of oil and gas is controlled largely by stratigraphy, with lenticular sands pinching out into shales.
