InterOil Confirms Extended Gas Column at PNG's Antelope-1

InterOil has successfully drilled an additional 295 feet of reservoir and flowed natural gas at a rate of 13.1 million standard cubic feet per day (MMSCFPD) from a 210 feet interval at the current base of the Antelope-1 well in Papua New Guinea.


  • Drilled and cored 295 feet lower in the reservoir, with gas confirmed by logging and testing, establishing a new gas column of 2,300 feet (701 meters).
  • A 210 feet (64 meter) interval was tested by DST#1 between 7,861 feet (2,396 meters) and TD (total depth) at 8,071 feet (2,460 meters) in Antelope-1 and produced gas at a rate of 13.1MMSCFGD.
  • No formation water was indicated in the test supporting wireline log analysis which indicated gas to TD.
  • The net pay over the 2,300 foot logged interval, increased to 2,077 feet giving a net to gross of 90% with an average porosity of 8.8%.
  • This initial drill stem test (DST#1) was programmed to test the lowest reservoir for water. Evaluation of the main sections of the reservoir will be completed following further drilling.

Based on confirmation by logs and DST#1 of a continuous gas column from the top of the reservoir to the current depth, InterOil plans to deepen the well a further 820 feet to approximately 8,892 feet. Further objectives are to locate and test the lowest limit of hydrocarbons in the reservoir and to penetrate a lower anomaly identified on seismic data.
