Premier Makes Significant Resource Upgrade At Zama

(Premier, 27.Jun.2019) — Premier has significantly increased its resource estimate of the Zama field offshore Mexico, following its evaluation of the data acquired from the highly successful Talos Energy-operated Block 7 Zama appraisal campaign. The campaign comprised two appraisal wells (Zama-2 and Zama-3) and a vertical side-track (Zama-ST1) which was flow tested.

The latest appraisal well, Zama-3, has proven the lateral continuity of the reservoir 2.4 kilometres to the south of Zama-1 with the quality of the reservoir sands encountered at the upper end of expectations.

A comprehensive set of data was acquired during the campaign, including high resolution wireline logs, extensive fluid sampling and pressure data, together with the recovery of over 400 metres of core and a drill stem test to confirm well productivity.

The data has demonstrated reservoir properties at the upper end of expectation, including a higher net-to-gross ratio, better porosity and increased hydrocarbon saturation. This has resulted in a higher estimated oil-in-place and ultimate recovery from the Zama field. Consequently, Premier has refined its gross resource estimate of the Zama structure to 670-810-970 mmboe (P90-P50-P10).

“We are delighted with the results of the latest Zama appraisal well which, together with the positive results from the earlier appraisal wells, has caused us to significantly upgrade our resource estimates of the Zama structure. Our focus now turns to selecting the optimal development for the field, ahead of taking a final investment decision next year.”

– Premier CEO Tony Durrant
