The well is in the Antelope-4 sidetrack-1 in the Petroleum Retention License 15 in the province. The logs measure 182 vertical meters (597 feet) of dolomite and a vertical gross gas column of about 339 meters (1112 feet).
InterOil chief executive officer Dr Michael Hession said the field continued to surprise on the upside. “First, we intersected the top of the reservoir 36 meters (118 feet) higher.
“Than the original Antelope-4 penetration and second, our interpretation of data from Antelope-4 and Antelope-5 suggests that the field-wide gas-water contact is deeper than previously interpreted,” he said.
The PRL 15 joint venture intends to begin drilling Antelope-6 in December this year as part of the appraisal programme to define the resource for the Papua LNG (liquefied natural gas) project.
The joint venture is considering an additional appraisal well on the western flank of the Antelope field that could add an incremental volume of 1 to 3 Tcfe.
