Dallas firm fracs Thrace basin tight gas sands

HOUSTON, Nov. 10
-- TransAtlantic Petroleum Ltd., Dallas, pumped the first modern frac stimulation in Turkey in October at the Kepirtepe-1 well on Thrace basin License 3791.

The operation, in partnership with state owned Turkiye Petrolleri AO, was designed to test noncommercial gas shows in tight Oligocene Mezardere sands at 12,000 ft. The single-stage frac was pumped using TransAtlantic’s high-pressure, high-volume pumping units, sand blenders, and support equipment.

Initial flow rates exceeded 4 MMcfd of gas with some condensate and water. TransAtlantic expects to complete cleaning the perforations and testing the well with coiled tubing and nitrogen units in late-November.

The initial flow rate, while preliminary, points to potential production from unconventional tight sands, and the company expects to continue applying modern frac technology to existing and new wells (see map, OGJ, Oct. 4, 2010, p. 56).

By yearend, the company expects to have completed single-stage fracs in four of the five known reservoirs on its Thrace basin acreage. After refining the frac techniques on the less expensive reentries, the company will drill locations optimized for unconventional potential.

Five rigs should be running by mid-2011, including two on shallower conventional targets and three on deeper targets.
