Petroleum geology of East Dykesville field, Smackover C sand, Claiborne and Webster Parishes, Louisiana
The discovery in 1980 of gas production in the Smackover C sand in the East Dykesville field of Claiborne and Webster Parishes, Louisiana, extended the productive limits of this reservoir 6 mi (10 km) south of the production in the Haynesville field. The development of East Dykesville field has revealed three productive fault blocks within an area 6 mi (10 km) by 3 mi (5 km). The Smackover C and B sand of East Dykesville are present 700 ft (213 m) above the Louann Salt as a portion of a more or less continuous sand body covering an area 9 mi (15 km) from east to west. This sand body extends southward from the Arkansas-Louisiana state line for more than 10 mi (16 km), and also produces at the Haynesville field. Production has been encountered in the C sand at East Dykesville from 10,912 ft (3326 m) subsea down to 11,605 ft (3536 m) subsea, an interval of 693 ft (211 m). The source of the sediments which constitute the Smackover C sand appears to be north of the sand body, as it thickens to more than 100 ft (31 m) in the Red Rock-Haynesville area and thins southward. The sand also thins both to the east toward Haynesville and to the west toward Shongaloo. The C sand is 60 ft (18 m) thick in the north portion of East Dykesville field and thins to 20 ft (6 m) in the most southern wells. Isopach studies suggest a submarine-fan depositional environment on a stable shelf.
