HOUSTON, Mar. 18 -- An appraisal well in Taq Taq field in Iraqi Kurdistan has flowed at a combined rate of 44,240 b/d of 48° gravity oil with a low gas-oil ratio.

Three Cretaceous intervals were tested separately at the TT-10 well, drilled on 3D seismic into the crest of the field's main formations.

The well is the last in an appraisal program by Taq Taq Operating Co., a joint venture of Genel Enerji AS and Addax Petroleum Corp., Calgary. The companies submitted a field development plan to the Kurdistan Regional Government earlier this month.

A 136-m upper Shiranish interval flowed at a rate of 17,700 b/d, and an 85-m lower section made 13,780 b/d.

A 67-m upper Kometan interval flowed at a rate of 19,380 b/d, and a 49-m lower interval made 14,800 b/d.

A 136-m Qamchuqa interval flowed at a rate of 11,080 b/d.

Oil rates from all of the intervals were restricted by a 2-in. choke.

TD is 2,247 m. The operating company spud the well in August 2008 and delayed testing so the well could be hooked to an early production system, allowing for test oil to be sold later.

"Interpretation of data acquired from the TT-10 well, including wireline logging and core samples, confirmed the presence of a significant and extensive fracture system in the tested formations as observed in the previous Cretaceous appraisal wells. In addition, the log analysis performed indicates that matrix porosity increases towards the center of the field," Addax Petroleum said.

The 30,000 b/d early production system is complete and is to be expanded to as much as 60,000 b/d by mid-2009. Taq Taq Operating is making intermittent oil sales for trucking to local refineries.

The Kurdistan-1 rig spudded the Kewa Chermila exploration well in the Taq Taq license in February 2009. Drilling is to take 120 more days.
