InterOil said that logs from the Antelope-4 sidetrack-1 well in Papua New Guinea’s Petroleum Retention License 15 (PRL 15) confirm a southern extension of the gas-bearing dolomite in the Elk-Antelope field. The wireline logs intersected the top of the reservoir at a point 118 ft higher than the initial Antelope-4 well’s penetration, and new well data interpretation suggests a deeper gas/water contact for the field than previously thought, the company said. Total is the operator for the PRL 15 joint venture with a 40.1% interest. InterOil (36.5%), Oil Search (22.8%), and minority shareholders (0.5%) are the other participants.
