SYDNEY, Australia – Proved and probable gas reserves at Kupe field now are higher than originally estimated as result of a detailed reserves review, says Origin Energy as operator for the Kupe Joint Venture. Initial gas reserves are up 8%, LPG reserves by 5%, and condensate by 27%.
The reserves review integrated new petrophysical, fluid sample, and well test information from development wells drilled in 2008 with full field static and dynamic reservoir models. The models now include new technical information from early field production.
“Following a successful commissioning and early commercial production, we are delighted to announce a significant increase in field reserves which enhances Kupe’s ability to continue to make a significant contribution to New Zealand's gas and LPG supply needs for the next 15-20 years,” says Chris Bush, Origin Energy New Zealand’s general manager.
Kupe, in PML38146 in the offshore Taranaki basin, New Zealand, is a gas/condensate filled reservoir in the Farewell formation. Kupe Gas Project itself, a complex offshore and onshore production system, officially opened on March 18, 2010, and became fully operational post commissioning on March 22.
