**Premier Oil Plc** (LON:PMO) noted the press release by Talos Energy, the operator
of Block 7 offshore Mexico, announcing 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.

DST operations were successfully conducted on Zama-2ST1 and a combined oil flow 
rate of 7,426 bopd was achieved from two separate flow tests over a total perforated
interval of 248 feet. As planned, rates were restricted due to limited drawdown 
to prevent sand production. Flow and pressure measurements indicate a prolific reservoir.

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.

> **Tony Durrant, Premier Oil Chief Executive, commented:**
> “We are very pleased by the productivity demonstrated by this well and we continue
> to collect further evidence that Zama has a world-class reservoir with excellent
> quality and well-connected sands. This has positive implications for the expected
> ultimate recovery from the field and will help us to optimise the field development.
> We look forward to the conclusion of the Block 7 appraisal programme with the 
> Zama-3 well.”
