Oil Search, the largest oil and gas exploration and development company of Papua New Guinea (PNG), said that its Barikewa 3 appraisal well successfully completed a drill stem test.

The operator of Petroleum Retention Licence 9 (PRL 9), said the well produced gas from a 14 metre interval of the Toro Sandstone.

The well flowed gas to surface at 35 million standard cubic feet of gas per day (mmscf/d) on a 68/64” choke.

Onsite analysis of the gas from the drill stem test and earlier wireline sampling confirms a dry gas with approximately 20 per cent nitrogen and very low levels of other impurities, in line with pre-drill expectations.

The main flow period of this test was witnessed on Tuesday, 7 August 2018 by a high-level delegation including the Governor of Gulf Province, Chris Haiveta, Acting Secretary for the Department of Petroleum, Kepsey Puiye, the Acting Director of the Department of Petroleum, Bob Sari, along with other senior Department officials.

Governor Haiveta highlighted Oil Search’s significant successful and ongoing investment in exploration and appraisal activities in the region and reaffirmed the support of his administration.

Barikewa 3 was spudded in late June and reached a total depth of 1,943 metres on 15 July 2018. The well successfully encountered gas in the target Toro and Hedinia Sandstone reservoirs, at depths in line with predrill expectations. A gas-water contact was intersected in the Hedinia Sandstone.

Both reservoirs were well developed, with the Toro reservoir having better than expected thickness and quality. As planned, the well will now be plugged and abandoned.

The Barikewa 3 appraisal well has successfully achieved its appraisal objectives through the collection of modern data which will help constrain the field’s resources and assist in establishing the optimal commercialisation pathway.

Participants in the well are Oil Search (PNG) Limited – 45.1 per cent, Barracuda Limited – 40.1 per cent and NPCP Oil Company Pty Limited – 14.9 per cent.
