Sidetrack opportunity

THE Oil Search-managed P’nyang South 1 appraisal well in Papua New Guinea’s Western Province will be plugged to prepare a sidetrack to further hunt for the gas zone which was recently penetrated.

Two weeks ago the well intersected a 184m gross gas zone, providing hope that the well would hit the goal of doubling resources to 2 trillion cubic feet of gas in the wider P'nyang area.

Subsequent drilling targeted the underlying Koi-Iange sandstone, with this 81m of drilling along with a formation evaluation program now being completed.

Oil Search said the preliminary interpretation of the data indicated the sandstone was "water wet" which was the same for most oil and gas reservoirs, as opposed to "oil-wet" - a a type of reservoir which was often a poor producer.

"The forward plan is to drill a sidetrack to further constrain the downdip extent of the gas zone intersected in the Toro to P'nyang reservoir interval," Oil Search said.

Oil Search is drilling the well on behalf of its operator ExxonMobil.

Once complete, the rig will move east to spud the ExxonMobil-operated Trapia-1 exploration well in the Southern Highlands.

Exxon has a 49% stake in P'nyang South-1, Oil Search owns 38.5% while JX Nippon owns 12.5%.
