HOUSTON, June 21 -- The Alabama Oil & Gas Board has reported a completion test earlier this year of a modest Devonian gas well off the southern flank of the Black Warrior basin.
EOG Resources Inc., Houston, filed a test rate of 120 Mcfd of gas with 120 psi flowing tubing pressure on a 24/64-in. choke with 118 b/d of water from Devonian perforations at 8,150-8,763 ft. Test date is Mar. 4.
The company's 1 Bayne Etheridge 36-9 well, in 36-20n-2e, Greene County, Ala., is 13 miles south-southeast of Eutaw, Ala. Permitted to 10,350 ft, it went to TD 9,509 ft.
Generalized stratigraphic charts of the Black Warrior basin show two units in the Devonian, the Chattanooga shale underlain by a thicker cherty limestone.
The well site is 40 miles south of nearest Black Warrior basin production in Pickens County and 3 miles northeast of the ARCO Oil & Gas Co. 1 ARCO-Amoco Koch well, drilled to TD 15,600 ft in 10-19n-2e, Greene County, in 1983-84. It was abandoned.
This well site is 140 miles southwest of a budding play for gas in Cambrian Conasauga shale in the Gadsden, Ala., area (OGJ Online, Jan. 23, 2007).
