Norwest Announces Dominant Gas Zones at Arrowsmith-2

Norwest Energy reports that evaluation of the Arrowsmith-2 dataset and well test results indicate that the Carynginia Formation and Irwin River Coal Measures (IRCM) are the dominant zones for gas production.

“During the well test, the production logging tool (PLT) tested flow conditions over the range 2,700 metres to 3,301 metres, including the perforated zones of the Carynginia, IRCM and High Cliff Sandstone (HCSS). These zones had a previously reported average commingled surface gas rate of 312,299 scf/d (Oct 2013), however the production logging program was the first opportunity to record down-hole contributions from each perforated zone,” the company said.

With two target intervals having the potential to produce significant quantities of hydrocarbons, the selection of the target zone and location to drill Arrowsmith-3 will be finalised by integrating the results of the 3D seismic acquisition program scheduled for the last quarter of 2014, says Norwest Energy.

Norwest Energy Chief Executive Officer Peter Munachen said that the final test work conducted at Arrowsmith-2 and analysis of results had validated the company’s high expectations for the proposed Arrowsmith-3 horizontal well and the way forward for the Arrowsmith field.

“Overall results at Arrowsmith-2 have been very encouraging. It is the first shale gas project in Western Australia, and through the efforts of our dedicated project team and support of the Joint Venture partners we have achieved all project objectives,” Munachen said.
