HOUSTON, Sept. 24 -- NGAS Resources Inc., Lexington, Ky., is placing under test its first two horizontal wells in Mississippian Weir sandstone in Roaring Fork field in the Appalachian basin. The wells were drilled in Letcher County, Ky.
The first well, with a 10-stage water frac in a 2,040-ft lateral at 3,600 ft true vertical depth, is ready to be placed on pump and will be connected to the gas gathering system around Oct. 1. The second well is to receive a 12-stage foam frac Sept. 27 in a 2,500-ft lateral at 3,600 ft TVD.
The company expressed encouragement with initial oil and gas shows during clean-up at the first well. Drilling the Weir horizontally should contribute higher proportions of crude oil to the production mix, the company said.
Weir is the primary producing formation in Roaring Fork field on the Kentucky-Virginia line, where some 500 Weir wells are producing oil and gas. In Amvest field to the southwest, NGAS has 78 vertical Weir producing wells.
The Weir formation is 170-180 ft thick in the area. NGAS has more than 70,000 undeveloped acres in the two fields and plans to develop the Weir horizontally with 100-acre spacing upon successful completion of the second test well. The company is permitting four more horizontal Weir wells for drilling this winter.
