Junior partner Australian Worldwide Exploration (AWE) said wireline logging operations confirmed Trefoil-1 had intersected about 50 metres of net gas pay over eight zones in good quality sandstone reservoirs within the Intra Eastern View Coal Measures.
This is the same geological formation that contains the gas-bearing sands being developed at the nearby Yolla gas and condensate field.
AWE says the gas is of high quality with only about 3% carbon dioxide and liquids content ranging from 50 to 100 barrels of liquids per million cubic feet of gas. The “in-place” resource for the field is probably in the range of 100 to 300 billion cubic feet of gas and 7 to 21 million barrels of associated liquids, the company said.
The production test program will be conducted over two separate intervals, from 3040-3047 metres and 3141- 3150 metres.
"These intervals are from the lower quality pay zones in the well, and if productive, will go a long way to establishing the commercial viability of a development of the Trefoil field," said AWE managing director Bruce Phillips.
"If the Trefoil field is ultimately developed, the nearby White Ibis gas and condensate field will also become a serious candidate for commercial development as part of the overall BassGas Project."
