PA Resources completes drillstem test at Diega I-8ST well offshore Equatorial Guinea

Offshore staff

STOCKHOLM, SwedenPA Resources has completed the long-term drillstem test on the Diega accumulation in block I offshore Equatorial Guinea.

An initial pilot well, I-8, encountered 12 m (39 ft) vertical thickness of good-quality oil pay with no water and so established the deepest known oil on the Diega accumulation. Subsequently, the planned horizontal side track I-8ST drilled 400 m (1,312 ft) of oil pay of similarly good quality and was tested for one month at constrained rates up to 7,300 b/d.

The well has been suspended for re-use as a future production well. The test confirmed lateral reservoir continuity and absence of reservoir compartmentalization. Also, the test will permit the submission in 2014 of a plan of development for Diega as a subsea tieback to the Aseng FPSO, targeting first oil in 2016.
