Significant resource upgrade at Zama following conclusion of appraisal
campaign
27 June 2019
Premier is pleased to announce that it 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).
Tony Durrant, CEO, commented:
"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."
