Haynesville gas flows as high as 28 MMcfd

By OGJ editors
HOUSTON, Dec. 9 -- Three operators reported new horizontal completions in Jurassic Haynesville shale at rates as high as 28.2 MMcfd of gas.

The three companies, Petrohawk Energy Corp. of Houston and Comstock Resources Inc. and EXCO Resources Inc. of the Dallas area, plan much more activity in the Haynesville in East Texas and Northwest Louisiana.

Petrohawk reported the 28.2 MMcfd rate at its Sample 9-1 in 9-14n-11w, Red River Parish, La., about 12 miles south of Elm Grove gas field. The rate came on a 30/64-in. choke with 7,100 psi flowing casing pressure.

Petrohawk's Brown 17-4 in 17-16n-11w, Bossier Parish, gauged 23.4 MMcfd on a 26/64-in. choke with 7,700 psi FCP. And its Goodwin 9-5 in 9-16n-11w, Bossier Parish, made 21.1 MMcfd on a 26/64-in. choke with 6,750 psi FCP.

The company plans to complete five more Haynesville shale wells by yearend 2009.

Initial flow rate is 9 MMcfd at Comstock's BSMC LA 7-1H well in Toledo Bend North field, De Soto Parish. The flow came from a 4,300-ft lateral at 11,750 ft true vertical depth after a 10-stage frac.

Comstock is running another 10-stage frac at its Collins LA 15-1H well in Logansport field, also in De Soto. It has a 4,200-ft leg at 11,350 ft. The company has a 22% interest in the Gamble 24-1H well at Logansport, drilled to 11,800 ft TVD with a 3,950-ft lateral.

Comstock has drilled the vertical portion of two other Haynesville wells. Bogue A-6H in Waskom field in Harrison County is to get a 4,000-ft lateral, and Green 13H in Blocker field in Harrison County is to get a 3,700-ft lateral.

Comstock is drilling vertically at Headrick 1H and Hart 1H in Logansport and Moneyham 7H in Longwood field. Each is due a 4,000-ft leg.

EXCO said its first Haynesville horizontal well, Oden 30H6 in De Soto Parish, averaged 22.5 MMcfd on a 26/64-in. choke with 7,800 psi FCP. It has a 4,481-ft lateral at 12,304 ft TVD.

EXCO has two operated horizontal wells, one vertical well, and two outside-operated horizontal wells in the play and plans to drill 25 or more horizontal Haynesville wells in 2009.
