HOUSTON, Nov. 17
-- Unit Corp., Tulsa, is in final stages of completing a 50 MMcfd turboexpander gas processing plant in the northeastern Texas Panhandle, where it is stepping up horizontal drilling in the Granite Wash oil and gas play.

The new plant, in Canadian, Tex., will bring processing capacity at the company’s Hemphill facility to 100 MMcfd.

Unit expects to complete six Granite Wash horizontal wells in the last quarter of 2010 compared with one each in the first and second quarters and three in the third quarter. It added a fourth rig in mid-September 2010. The company will run three to four rigs in the play in 2011 and bring on line two to three wells/month.

Of the three third quarter Granite Wash B completions, Webb A-4H is making 691 b/d of oil, 4.1 MMcfd of gas, and 449 b/d of natural gas liquids with 1,200 psi flowing casing pressure, and Webb 3H despite an apparent downhole restriction had a peak rate of 165 b/d of oil, 2.2 MMcfd of gas, and 240 b/d of NGL. Unit holds 83% working interest in both.

Temple A-1H peaked at 182 b/d of oil, 960 MMcfd of gas, and 105 b/d of NGL from a shorter 2,000-ft lateral and has a higher water cut due to communication during the frac treatment with a wet sand below the pay sand. Unit installed a submersible pump.

Unit fracture treated two horizontal Granite Wash “A” wells in late October and secured frac dates in November and December for the wells being drilled.

Unusually wet weather, especially in the Granite Wash play area, and delays in securing frac services and connecting wells hampered the first quarter drilling and completion pace. The company has scheduled fracturing services for all 2011 Granite Wash wells.
