PA Resources completes long-term drillstem test in Equatorial Guinea

PA Resources AB has completed a long-term drillstem test on the Diega accumulation on Block I in Equatorial Guinea, resulting in the release of the Atwood Hunter rig.

An initial pilot well, I-8, encountered 12 m 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 sidetrack I-8ST drilled 400 m of oil pay of similarly good quality and was tested for 1 month at constrained rates up to 7,300 b/d of oil.

The well has been suspended for reuse as a future production well. The test confirmed lateral reservoir continuity and absence of reservoir compartmentalization and will permit the submission in 2014 of a plan of development for Diega as a subsea tieback to the Aseng floating production, storage, and offloading vessel, targeting first oil in 2016.

Mark McAllister, PA Resources’ chief executive officer, said, “We indicated in 2013 that we expected a near-term field development in Block I, conservatively of the order of 30 million bbl. However, initial interpretation of these well results is consistent with our expectations of significantly larger reserves and further Diega drilling is likely in Block I, where the down-dip limit of the field has yet to be established.”
