Pancontinental to appraise Walyering gas field in Western Australia

Pancontinental Oil & Gas and UIL Energy are planning to undertake a 90km² 3D survey in November this year to appraise the Walyering gas field in Western Australia’s Northern Perth basin.

Discovered in the 1970s, the field is crossed by the Parmelia gas pipeline. Its discovery well flowed naturally at up to 13.5 million cubic feet per day (MMCFD) from conventional sandstone reservoirs.

Pancontinental Oil & Gas has the right to acquire a 70% operated interest in the southern part of exploration permit EP 447, which includes the gas field.

As most of the structure remains untapped, the company expects a 57% chance of finding gas in the central high area, which is mapped more than 200m shallower than the highest gas intersected in the peripheral wells.

Pancontinental Oil & Gas CEO John Begg said: “We have been steadily working away on Walyering behind the scenes and are very pleased with the increased scale and materiality that has emerged for Pancontinental.

“That there is a prominent central high, with the reservoir top hundreds of metres higher than the historic gas intersections, seems very clear from our mapping.”

The planned 3D seismic survey aims to obtain greater mapping definition at gas reservoir levels.

If survey data supports the expected size of the undrilled field compartments, the company will contemplate drilling of at least one appraisal/development well next year to identify recoverable gas in excess of the current P90 or low-resource estimate.
