Southern Energy to drill three horizontal wells in Mississippi

Southern Energy Corp. will spud three Selma Chalk horizontal wells in Gwinville field in the northern part of Jefferson Davis County, Miss. targeting natural gas. The wells will be over 50% longer and have over 50% more sand pumped than past horizontal wells in the area, the company said.  

The three wells will be drilled from the same surface pad site and batch drilled for operational and capital efficiencies. First production is expected in April 2022. Following successful results, Southern Energy will drill in a second zone at Gwinville called City Bank.

Gwinville is part of the Mississippi interior salt basin (MISB) in the northeastern Gulf Coast region covering a total area of 6,000 sq mi, extending from northeastern Louisiana to southwest Alabama. MISB has produced more than 15 billion bbl oil and about 6.5 tcf gas to date.
