MAJOR GAS DISCOVERY REPORTED AT DEEP TEST IN ARDMORE BASIN

A North Texas deeper pool test along the Red River appears to be a major gas discovery in the southeastern Ardmore basin.

Gene G. Heape, a Dallas independent deepening a former dry hole in Northwest Grayson County, said the well appears to be a significant discovery in a deeper pay.

The well is Heape's 1 C.A. Matthews, in J. Murphy survey, A-799, 5 miles north of Sandusky, Tex., and 16 miles southwest of Madill, Okla.

Local reports credited the well as having 202 ft of pay and flowing gas at the rate of 40 MMcfd during a drillstem test of Cambro-Ordovician Ellenburger several hundred feet below old total depth of 15,814 ft.

No drillstem test has been conducted on the well, being drilled with gel mud, but there is no question it appears to be a major discovery, Heape said last week. Total depth is 20,500 ft, and liner was being run. More information will be released soon, Heape said.

Reentry operations began last February at the well, originally drilled in 1970 by Jake L. Hamon, Dallas. Site is just east of Ordovician Oil Creek gas production in Gordonville field, which Hamon discovered the same year.

Heape's contractor for the deepening is Helmerich & Payne International Drilling Co., Tulsa.

During original drilling, the well topped Oil Creek lime at 15,108 ft, Oil Creek sand at 15,696 ft, and Ordovician Joins lime at 15,780 ft, Petroleum Information, Denver, reported.

OTHER EXPLORATION

A modest amount of Arbuckle exploration is in progress in the Ardmore basin within about 30 miles of Heape's well.

Arbuckle exploration has accelerated in the basin since CNG Producing Co., New Orleans, opened Cottonwood Creek oil field in Carter County in late 1987. That reservoir, now under waterflood, was discovered by a well that flowed for a time at rates of more than 3,000 b/d of oil.

Heape's well is about 33 miles southeast of Cottonwood Creek field.

It is 5-7 miles south-southwest of South Powell field in Marshall County, Okla. That field produces oil and gas from multiple formations from Pennsylvanian Deese sand at 1,300 ft to Oil Creek below 16,000 ft.

CNG is drilling an Arbuckle test across the river from Heape's well, and several Arbuckle wildcats are under way in Carter County, Okla.

CNG spudded in January 1991 at 1 Askew, 13-7s-2e, Love County, Okla., a planned 15,000 ft Arbuckle deeper pool test in Southwest Enville field. Site is about 10 miles northwest of Heape 1 Matthews.

L.E. Jones Production Co., Duncan, Okla., spudded in late April at 1 Keith Walker, 15-5s-1e, a planned 14,500 ft Arbuckle deeper pool test in East Brock oil field of Carter County.

About a year ago, Park Avenue Exploration Co., Oklahoma City, drilled an Ellenburger wildcat in Northwest Collin County, Tex., about 22 miles south-southwest of Sherman.

The Sherman basin wildcat, 1 USF&G Merritt, 1 mile north-northeast of Celina, Tex., was abandoned at 5,200 ft in Ellenburger. It topped Basal Cretaceous at 2,592 ft, Atoka at 4,580 ft, Simpson at 5,104 ft, and Ellenburger at 5,156 ft.
