NORWEST Energy is set to start acquiring 3D seismic data near its Arrowsmith project, located north of Perth on the onshore EP 413 permit area.

The 106 square kilometre survey is to assess the extent of the gas resource surrounding the already drilled Arrowsmith 2 well, as well as assisting in defining the optimal location and target formation for Norwest’s first horizontal well – the Arrowsmith 3.

Norwest chief executive Peter Munachen said the results of the survey would make a significant contribution toward defining the commercial potential of the Arrowsmith project.

“We would like to take this opportunity to acknowledge the assistance provided by the Amangu people during the on-ground activities undertaken to date, which demonstrates the strong working relationship that has been developed with the traditional owners of the Arrowsmith land,” he said.

In an announcement made on 16 April, Norwest said it was mobilising its seismic acquisition crew and equipment to the site, located between the towns of Eneabba and Dongara.

The survey, which had been designed in consultation with the Department of Parks and Wildlife and local traditional owners, was expected to take about 21 days to complete.

On completion of the survey, vegetation rehabilitation will be undertaken including annual audits to demonstrate progress and Norwest said it was confident of meeting all rehabilitation milestones set by the respective government agencies.

Processing and interpretation of the data will follow, the results of which should become available during the third quarter of the 2015 calendar year.

Norwest is operator of the EP 413 permit with a 27.945 per cent stake. The remaining shares are held by AWE (44.252%) and Bharat PetroResources (27.803%).
