Oil Search completes well tests in Alaska

Published by , Editor
Oilfield Technology,

Oil Search has completed testing of the Nanushuk reservoirs encountered in the Mitquq 1 ST1 and the Stirrup 1 wells, located in Alaska, US.

Both wells were drilled, logged, cored and flow tested. The flow tests included a clean-up, flow period and a pressure build-up prior to the final flow test to assess well deliverability.

Mitquq 1 ST1, a sidetrack from the Mitquq 1 oil discovery, located 9 km east of the proposed central processing facility of the Pikka Unit Development, encountered a net pay zone of 52.5 m (172 ft) with a gas cap of 9 m (29 ft). On test, the well flowed at a stabilised rate of 1730 bpd from a single stimulated zone.

The Stirrup 1 exploration well, located approximately 12 km west of the 2017 Horseshoe discovery well and 35 km southwest of the proposed Pikka Unit development infrastructure, encountered an oil column with net pay of 23 m (75 ft). On test, the well flowed at a stabilised rate of 3520 bpd from a single stimulated zone.

The two Mitquq (Mitquq 1 and Mitquq 1 ST1) and Stirrup 1 oil discoveries, together with the Mitquq 1 ST1 and Stirrup well tests, have provided valuable information regarding the geology and well productivity of the Nanushuk play in the areas to the east and south west of the Pikka Unit. In addition, the discoveries support the potential for material resource growth in the company’s leases.

With testing complete at both well locations, the crews are demobilising and expected to be off-location by mid-April.
