Successful appraisal drilling at Zama – which confirmed the discovery over 2.4 kilometres and showed reservoir quality at the upper end of expectations – has led to a significant upgrade to Premier’s view of the asset.
Zama is now estimated to have some 810mln barrels of gross resources (P50m mean estimate), with the estimate range (P90 to P10) pitched at 670mln to 970mln barrels.
It underlines Zama’s credentials as a ‘world class’ discovery.
"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,” said Tony Durrant, Premier chief executive.
“Our focus now turns to selecting the optimal development for the field, ahead of taking a final investment decision next year."
