Austral Pacific Energy is due to begin appraisal work later this year on the Stanley gasfield in Papua New Guinea.
The move comes after the company won a five year extension to the term of Petroleum Retention Licence (PRL) 4, which covers the Stanley field in the western province of Papua New Guinea.
Austral Pacific Energy, through a wholly owned subsidiary, Austral Pacific Energy (PNG) Limited, holds a 28.92 percent interest in PRL 4 and is the new operator of the licence.
The other partners in PRL 4 are InterOil Corporation, through its wholly owned subsidiary SPI (157) Ltd, (43.13 percent) and Horizon Oil Limited (27.95 percent).
"This licence represents an integral part of the company's strategy to commercialise gas opportunities in the Forelands region of Papua New Guinea," said chief executive officer and president, Thom Jewell.
The licence was granted originally in 2000 for a term of five years to appraise the Stanley discovery.
In 2005, the then operator of the PRL 4 Joint Venture, Santos, sought an extension to the term of the licence. The extension is for five years and is backdated to August 2005.
The Stanley-1 well was drilled in 1999 to a total depth of 3219m. Thirty five meters of excellent quality Toro reservoir was intersected at 3125m with 13.5m of gross gas pay interpreted from wireline logs.
Appraisal of the Stanley discovery will begin later this year with a 43km infill 2D seismic programme. It will address the structural uncertainty of the Stanley Field and determine the optimum location for an updip Stanley-2 appraisal / development well.
At the same time, negotiations will continue with a potential buyer of Stanley gas. The gas is proposed for use in electricity generation for the OK Tedi mine ("the Stanley Gas Project").
The Stanley Gas Project is an exciting project for Austral Pacific Energy, Jewell said.
"Bringing gas to market in Papua New Guinea is a significant challenge, but with a ready buyer for Stanley gas we have a unique opportunity to begin realising the potential of our extensive licence interests there."
