EXPORT CRUDES FOR THE '90S PAPUA NEW GUINEA'S FIRST COMMERCIAL CRUDE ASSAYED
Anne K. RhodesRefining/Petrochemical Editor
Light, sweet Kutubu crude from near Lake Kutubu in Papua New Guinea has been assayed. Production of the 44-gravity, 0.04-wt % sulfur crude-Papua New Guinea's first commercial oil-began in June 1992 (OGJ, June 29, 1992, p. 44).
Chevron Niugini Pty. Ltd., acting as operator for a group of six oil companies, discovered oil in the Iagifu-Hedinia and Agogo fields. Other interests are held by the Papua New Guinea government, British Petroleum Co. plc, Ampolex, BHP Petroleum Pty. Ltd., Oil Search Ltd., and Japan PNG Petroleum.
Chevron built production facilities and laid an export pipeline from the central facility to landfall on the Kikori River, then to a platform in 66 ft of water in the Gulf of Papua (see OGJ, Aug. 3, 1992, p. 50 and p. 68 this issue).
Most of the early production will likely be sold to refineries in Sydney and Brisbane. Production of Kutubu is expected to reach 100,000 b/d, and possibly 140,000 b/d.
