HOUSTON, Nov. 19 -- The Yousefieh-1 exploration well near Khurbet East oil field on Block 26 in northeastern Syria discovered an accumulation of 23° gravity oil, said Gulfsands Petroleum PLC and Emerald Energy PLC.
The 50-50 partners were moving appraise the discovery with a well at the north end of Khurbet East field that seeks to establish the oil-water contact and could be used later for water disposal.
Yousefieh-1, 3 km from Khurbet East production facilities, cut 63 m of net oil pay in the target Cretaceous formations and flowed 900 b/d without treatment from the shallowest 19-m interval. Porosity averaged 18.6%. TD is 2,139 m.
While preparing for the natural flow test, the well flowed at the average rate of 1,450 b/d for 3 hr through a 95/64-in. choke on gas lift. Preliminary results indicate good permeability. The entire reservoir was cored.
A smaller workover rig may be brought in to run further tests.
The companies, which identified the new play on 2007 3D seismic, plan to shoot more 3D to identify other prospects and leads nearby.
Meanwhile, cumulative production has exceeded 1 million bbl from Khurbet East field, averaging 11,500 b/d from two vertical and three horizontal wells with minimal reservoir production reduction.
