Antelope-4 Sidetrack-1 confirms high-quality reservoir

InterOil Corp. has stated that wireline logging from the Antelope-4 sidetrack-1 well in Petroleum Retention License 15 in Papua New Guinea has confirmed a southern extension of the Elk-Antelope field's high-quality, gas-bearing dolomite.

The logs measured 182 vertical m (597 feet) of dolomite and a vertical gross gas column of about 339 m (1112 feet).

InterOil Chief Executive Dr Michael Hession said the field continued to surprise on the upside: “First, we intersected the top of the reservoir 36 m (118 feet) higher than the original Antelope-4 penetration. Second, our interpretation of data from Antelope-4 and Antelope-5 suggests that the field-wide gas-water contact is deeper than previously interpreted."

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 Project.

The joint venture is also considering an additional appraisal well on the western flank of the Antelope field. This could add an incremental volume of 1 to 3 Tcfe.
