Wireline logging from the Antelope-4 sidetrack-1 well in petroleum retention license (PRL) 15 in Papua New Guinea (PNG) has confirmed a southern extension of the Elk-Antelope Field’s high-quality, gas-bearing dolomite, InterOil Corp. (NYSE: IOC) said in a news release.

The logs measured 182 vertical m (597 ft) of dolomite and a vertical gross gas column of about 339 m (1,112 ft).

The PRL 15 joint venture intends to begin drilling Antelope-6 in December as part of the appraisal program to define the resource for the Papua LNG project, the release said.

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