The Woodside Petroleum Ltd.-operated North West Shelf joint venture has begun production from the Persephone gas-condensate field in the Carnarvon basin off Western Australia.

Development of the field, in 125 m of water in licence WA-1-L about 135 km northwest of Karratha, was completed about 6 months ahead of schedule and 30% under budget.

The $1.2 billion (Aus.) project comprises two wells tied into a subsea production manifold and a 7-km flowline taking the gas and condensate to the existing North Rankin facilities that are integral to the North West Shelf gas project sending gas and liquids via dual export pipelines to the onshore LNG-domestic gas plant at Karratha.

Production from Persephone is expected to ramp up to about 290 MMcfd of gas.

The field was discovered in 2006 with Persephone-1 8 km northeast of the North Rankin Complex. The project was approved for construction in 2014.

Woodside is operator for the project. The JV partners are BP PLC, BHP Billiton Ltd., Chevron Corp., Royal Dutch Shell PLC, and Mitsubishi Corp.- Mitsui & Co. Ltd. Each company has a 16.67% interest.
