OKLAHOMA'S OUACHITA AREA BEGINNING TO STIR

Exploration is stirring in Ouachita rocks of southeastern Oklahoma.

Wells are completed or planned in the Potato Hills, Moyers, and Atoka areas of the Ouachita Province.

Deep and shallow drilling will start soon in a 9 sq mile area in the Potato Hills area of southern Latimer County (OGJ, Jan. 14, p. 79).

Montgomery Oil & Gas Co. Inc., Tulsa, received approval for spacing in the area in late January (see map). Seismic surveying is starting on the acreage.

The shallow drilling program will consist of eight wells to about 6,000 ft to assess potential in Ordovician Big Fork, Womble, and Mississippian-Devonian Arkansas Novaculite.

An unidentified Denver independent has taken a farmout from Montgomery and plans to drill a wildcat to at least 12,500 ft in 21-3n-20e, about 10 miles south-southwest of Talihina, Okla.

Wells in the northern part of the block are likely to penetrate the Windingstair fault, said Joe Loftis, Montgomery vice-president and engineering manager.

Potato Hills field consists of Big Fork gas wells in 32 and 31-3n-20e completed in 1960 and 1974, respectively.

MOYERS REENTRY

Hitchita No. 1 Partnership, Edmond, Okla., plans to reenter 1-16 Urfer, in Southwest Moyers field of Pushmataha County.

The company plans to test Arkansas Novaculite at 9,350-10,418 ft.

The former Midwest Oil Corp. drilled the well, and the former Jones & Pellow Oil Co. proposed to reenter it in 1981.

Reported log tops were Mississippian Stanley at 9,450 ft, Arkansas Novaculite at 9,456 ft, and Upper Ordovician Polk Creek shale at 10,530 ft.

Old total depth is 10,651 ft.

BIG FORK COMPLETION

BBR Oil Corp., Ardmore, Okla., and Fractal Oil Co., Tulsa, completed a small Ordovician Big Fork gas well in South Atoka Townsite field, Atoka County.

The 1 FHA, W 1/2 W 1/2 SE 15-3s-11e, in South Atoka Townsite field 6 1/2 miles south of Atoka.

It flowed 40 Mcfd of gas through an 8/64 in. choke with 20 psi flowing tubing pressure from Big Fork perforations at 2,358-2,476 ft. Total depth is 2,600 ft.

The well cut about 600 ft of Upper Big Fork, then encountered a thrust fault and drilled 500 ft of lower Big Fork, and was still in the formation at TD.

The well is about 3 miles from a Transok Inc. pipeline, and it might have been feasible to lay a line if a 500 Mcfd flow could have been obtained, such as perhaps by perforating more zone, said Matt Biddick of Fractal Oil in Norman, Okla.

BBR initially reentered the former Sohio Natural Resources Co. 1 Taylor, S/2 N 1/2 SE 15-3s-11e, in early 1990 intending to test Big Fork at 2,770-3,195 ft.

It found that drilling mud had penetrated Big Fork near the well bore, and skidded the rig to drill 1 FHA.

Natural Gas Pipeline Co. of America's new 24 in. gas system from Wilburton to Bennington passes east of the area in the western tier of sections in Range 13 East.
