Premier Oil Plc (PMO.L) Announced the successful drill stem test (DST) of the Zama-2 side track well (Zama-2ST1). This
follows the successful Zama-2 appraisal well which completed in January. The Zama-2ST1 logged
873 feet of gross oil bearing reservoir with a net-to-gross ratio of c. 70%, in line with expectations. In
addition, 714 feet of whole core was cut with 98% recovery. The rig will now move to drill the third and
final Block 7 appraisal well (Zama-3) to confirm lateral reservoir continuity and quality in the southern
part of the field. The programme remains ahead of schedule and under budget.
