Tchefuncte owns and operates the Lake Hermitage Field in Plaquemines Parish in the US state of Louisiana.
Current production in the field averages approximately 160 barrels of oil and 240mcf of gas per day.
Mesa Energy CEO Randy Griffin said that the acquisition of Tchefuncte will give Mesa a significant foothold on the Gulf Coast.
"The Lake Hermitage Field has stable existing production and we believe there is excellent upside potential from a number of drilling and recompletion opportunities," Griffin said.
The acquisition is subject to closing adjustments and various other customary terms and conditions.
