InterOil Corp. announces Papua New Guinea drill stem test results

InterOil Corp. has announced that during the last 7 hrs of drill stem test (DST) 2 at the Antelope-2 well in Papua New Guinea, the well flowed at a stabilised rate of approximately 11 million ft³/d on a 48/64 in. choke and the condensate to gas ratio (CGR) averaged 20.7 bbls/million ft³ of natural gas.  This is a 15% increase in CGR from DST 1, which was performed at the top of the reservoir.

Prior to initiating DST 2, casing was set in the well to a depth of 7290 ft short of total depth of 7415 ft due to an impassable ledge. The well was subsequently drilled an additional 213 ft, from 7415 - 7628 ft and DST 2 was conducted with a packer inside the casing shoe over the 338 ft openhole section from 7290 - 7628 ft.

The forward plan is to perform one more DST in the lower section of the current openhole, then drill and core from the current total depth into the targeted heavier condensate and potential oil zone where the company looks to perform additional DSTs and formation evaluation work.  Following testing and logging of the lower vertical section of the wellbore, InterOil plans to drill a horizontal lateral to explore a potential oil zone.

Phil Mulacek, Chief Executive Officer of InterOil, commented, ‘We anticipate that the higher condensate ratio tested in DST 2 of the Antelope structure will improve the previously estimated economics of the stripping plant proposed to be constructed in the Gulf Province.’
