Granite Wash Tight Gas

Granite Wash Tight Gas ImageThe Midcontinent Granite Wash is a series of tight gas plays (Lard Ranch, Buffalo Wallow, Stiles Ranch, and Colony West) that runs from the Texas Panhandle to Southwest Oklahoma. There is some oil production in the Granite Wash, mainly in Oldham and Gray counties in Texas. The sandstone reservoir is about 160 miles long and 30 miles wide. Operators are using both horizontal and vertical drilling to produce reserves from this longtime target.

Economic rates are achieved by multi-stage, slickwater fracture treatments and close attention to costs. There are over 2600 operating wells in the Granite Wash, and some of the operators include Chesapeake Energy, Newfield Exploration, Penn Virginia, Cimarex Energy, Questar, Linn Energy, Forest Oil, Apache Corp., BNK Petroleum, Devon Energy, and Cordillera Energy Partners III.

MORE DRILLING DUE NEAR ARIZONA CO2/HELIUM STRIKE

Sep 5, 1994 Further drilling is planned to evaluate an apparent carbon dioxide and helium discovery in East Central Arizona. A group led by Ridgeway Arizona Oil Corp., a subsidiary of Ridgeway Petroleum Corp., Calgary, will attempt to complete the apparent discovery from eight intervals between 1,450 ft and 1,710 ft in Permian Supai. The well is the Ridgeway/Canstar 1 Plateau Cattle Co., 15-12n-29e, Apache County (OGJ, July 4, p. 66).

TIGHT GAS SANDS DRILLING BUOYING U.S. E&D ACTIVITY

Nov 2, 1992 Patrick Crow Washington Editor A.D. Koen Gulf Coast News Editor U.S. federal tax credit for drilling wells in tight gas sands formations has contributed significantly to U.S. exploration and development activity. The credit, due to expire for new wells at yearend, has been a key factor in the rebounding U.S. active rig count in second half 1992. Drilling in tight gas sands currently accounts for as much as one third of the active U.S. rig count.

COMPARTMENTATION, FLUID PRESSURE IMPORTANT IN ANADARKO EXPLORATION

Jul 8, 1991 Zuhair Al-Shaieb Oklahoma State University Stillwater, Okla. Basin compartmentation, introduced by Bradley1 and Powley,2 is an important concept in the exploration and production of hydrocarbons in deep sedimentary basins. Compartmentation can arise in a number of distinct ways through the interplay of sedimentological, mechanical, and chemical factors. These compartments are most easily recognized by their abnormal fluid pressures.

TEXAS' LIGHTLY DRILLED DALHART BASIN GETTING MORE OIL EXPLORATION

Jun 24, 1991 G. Alan Petzet Exploration Editor The Dalhart basin of the northwestern Texas Panhandle, the state's least drilled prospective area, is showing signs of another round of exploratory drilling. Horizon Oil & Gas Co., Dallas, opened ERT (Granite Wash) field in Potter County at 102 Bivins Ranch 9 miles north of Amarillo in early June. The discovery well pumped 105 b/d of 37.7 gravity oil and 48 b/d of water with gas too small to measure from perforations at 5,820-5,913 ft. Total depth is

STRIPPER WELL PRODUCTION INCREASED WITH MEOR TREATMENT

Mar 18, 1991 Sidney J. Nelson, Phillip D. Launt RAM Biochemicals Inc. Raleigh, N.C. Stimulation of single wells by microbial injection has proved to be an effective technique for improving marginal oil production. Microbial stimulation is particularly suited for stripper wells because of the relatively low cost for process development and testing, and even lower cost for subsequent well treatments.

ULTRADEEP ANADARKO EXPLORATION RETURNS IN HIGHLY PRESSURED WASHITA COUNTY AREA

Dec 17, 1990 G. Alan Petzet Exploration Editor Ultradeep exploration is slowly returning to the Anadarko basin. An Oklahoma City independent spudded a wildcat in Washita County last week that is scheduled to evaluate mainly Siluro-Devonian Hunton and Cambro-Ordovician Arbuckle. The well is Park Avenue Exploration Co. 1-36 USF&G, in 36-9n-17w, about 6 miles southeast of Cordell, Okla. Drilling time to 26,000 ft is estimated at 320-365 days. Parker Drilling Co. has the drilling contract. Park Avenue began
