HOUSTON, July 24 -- A well in Bethany-Longstreet field in northwestern Louisiana has encountered gas in two Haynesville shale (Jurassic Lower Bossier) intervals, said Cubic Energy Inc., Dallas.
Log analysis at the Estes 7-1, in 7-14n-15w, Caddo Parish, 18 miles southwest of Shreveport, indicated an estimated 186 bcf of total shale gas in place for the 640-acre unit, 173 bcf of it free gas, in a lower shale zone at 11,420-11,890 ft and an estimated 100 bcf of total shale gas in place, 93 bcf free, in an upper shale zone at 10,730-11,150 ft.
TD is 11,950 ft, with 7-5/8-in. casing set at 10,208 ft and 4½-in. liner bottomed at 11,950 ft. A vertical completion is planned, and the well is to be horizontally drilled in the Haynesville later.
The estimated gas in place is similar to the volume Cubic Energy estimated in the Haynesville in company wells 6-7 miles north in Johnson Branch field. The rig is moving to drill Red Oak Timber 5-1, in 5-14n-15w, to the Haynesville with the same casing program.
A pipeline connection is expected to be completed in a few weeks at Johnson Branch, where the company has drilled three vertical Haynesville shale wells and eight vertical Cotton Valley-Hosston wells.
Cubic holds 49% interest in 12 sq miles of leases at Johnson Branch surrounded by a large block held by Chesapeake Energy Corp., Oklahoma City, and in 12 sq miles at Bethany-Longstreet in Caddo and De Soto parishes flanked by a large block held by Goodrich Petroleum Corp., Houston.
Cubic Energy operates in the field as Fossil Operating Inc. Holding the other 51% interest is Tauren Exploration, owned by Calvin Wallen, who is also chief executive officer of Cubic Energy.
