Successful well test of the Zama discovery

16 April 2019

Premier notes 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, 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."
