Capacity to gather and transport gas out of the western part of the Arkoma basin is growing.
Transok Inc., Tulsa, signed a volume commitment agreement with ARCO Natural Gas Marketing Inc., Dallas, covering a proposed westbound extension of Transok's Arkoma Pipeline.
Volume was not disclosed, but the agreement provides ARCO flexibility to deliver its Wilburton area production to any interstate pipeline Transok serves, They include Natural Gas Pipeline Co. of America, Phillips' Seagas system, ANR Pipeline Co., Williams Natural Gas Co., Panhandle Eastern Pipeline Co., and Northern Natural Gas Co. via a Northern intrastate subsidiary.
Transok has approved construction capital for the project contingent on obtaining further commitments from other producers. It has started engineering and acquiring right-of-way and hopes to obtain the added commitments shortly.
Arkoma Gas Gathering Inc., Tulsa, an affiliate of Texaco Inc., started up a wholly owned 40 mile, 8 in., 10 in., 12 in., and 20 in. gathering system in Pittsburgh and Atoka counties.
Connections like those of Transok and Texaco-Arkoma may be reducing demand for large diameter pipelines proposed to be laid eastward through the basin from Wilburton field.
TEXACO ARKOMA SYSTEM
Arkoma's system serves Pittsburgh, South Blanco, Daisy, and West Wesley gas fields (see map, OGJ, Jan. 9, 1989, p. 17).
The system connects with Arkansas Louisiana Gas Co. north and south of Blanco, Okla., and with Ozark Gas Transmission System north of Pittsburgh, Okla.
A newly built, 50 Mmcfd western leg extends from Pittsburgh about 12 miles south to Texaco's 1 La Fevers, a gas well in West Wesley field.
An eastern leg extends as far south as 41/2 miles southwest of Daisy, Okla., to three Energas Corp. wells in Daisy field.
Arkoma installed a compressor station, containing glycol dehydration equipment, with 20 MMcfd capacity. Arkoma said the central compression/dehydration equipment will be more efficient to maintain and operate than individual wellhead equipment presently in use.
The equipment will provide economies of scale that can be passed on to producers in competitive rates, better on line time, and improved field gas utilization, Arkoma said.
Part of the eastern leg of the system was built by another company about 5 years ago.
TRANSOK EXTENSION
ARCO made a significant commitment to Transok's proposed western extension, said Dick Krueger, Transok vice-president, gas supply, transportation, and marketing.
The 63 mile, 24 in. extension will run southwest from Wilburton to Transok's 30 in. north-south Texoma gas pipeline west of Atoka, Okla.
Transok placed in service last Oct. 11 a 23.6 mile, 16 in. pipe-line from Wilburton to near Red Oak, Okla., in Latimer County. It is transporting Wilburton field production (OGJ, Oct. 9, 1989, p. 36).
Preliminary state figures show burgeoning gas production from Latimer County, Okla., where western Arkoma basin drilling is centered.
Latimer production, mostly on the strength of flows from Wilburton field, was 8-14 bcf/month during JanuaryOctober 1989.
Gas runs from Latimer County were 1.55.6 bcf/month during 1986 before ARCO's Wilburton deep Cambro-Ordovician Arbuckle discovery.
Latimer has been one of Oklahoma's top producing counties most of the year, vying month to month with Roger Mills and Custer counties in the Anadarko basin.
Runs from Pittsburgh County have been 3.36 bcf/month during January-October 1989 compared with 2.5-5 bcf/month in 1986.
