Total: Second planned extended well test starts

 TOTAL E&P PNG Limited (Total), operator of Petroleum Retention Licence 15 (PRL15) in Gulf, says the second planned extended well test has commenced at Antelope-5.
InterOil Corporation said it had been advised that the extended well test would flow at Antelope-5 at around 50 million standard cubic feet per day for around two weeks before being shut-in to record the subsequent pressure build-up.
Pressure gauges have been placed in Antelope-1 as an observer well. The test is expected to take about one month to complete.
InterOil chief executive Dr Michael Hession  said the initial flow test conducted last June provided a good indication of the minimum connected volume in Antelope. The second test aims to further support those findings.
“To improve the certainty of the minimum connected volume, we have added additional pressure gauges and we plan to flow five times more gas than we did in our initial test last year.”
The company has also been advised by Total that the Antelope-6 appraisal well, located two kilometres east-south-east of the Antelope-3 well, was preparing to drill ahead at 1,120 meters (3,674 feet) true vertical depth sub-sea.
Antelope-6 spudded on December 23 last year, and has a proposed total depth of around 2,464 meters (8,084 feet) true vertical depth sub-sea. The PRL15 joint ventures are discussing an additional appraisal well to the west of Antelope-5. The decision whether to drill a further appraisal well will follow the evaluation of the Antelope-6 appraisal well and the results of the latest flow test at Antelope-5.
The joint venture participants, last July, unanimously endorsed recommendations from Total SA for key project infrastructure sites for development of the Elk-Antelope gas field.
The central processing facility for the Elk-Antelope gas field, on which the project is based, would be near the Purari River in Gulf. It is about 360 kilometres north-west of Port Moresby and would be connected to the LNG facility by onshore and offshore gas and condensate pipelines.
Caution Bay near Port Moresby had been selected as the site for PNG’s second liquefied natural gas plant. The project will be known as Papua LNG.
