The first well, KSG-57, formerly KPL-A, identified four intervals totaling 20 m of net sand for testing based on wireline log interpretation, formation pressure data from sequential formation testing, and sidewall core results. It is to be tested with a workover rig deployed at the site on Aug. 21.
