Woodside’s Persephone development ahead of schedule

Australian energy company Woodside Petroleum has informed that activities on the Persephone Project offshore Western Australia are going ahead of schedule.

The company said on Thursday that during the fourth quarter 2016 the well development activities were completed ahead of schedule and that the start-up could be expected in the third quarter of 2017.

The original start-up estimate was early 2018, but Woodside said in October last year that it could be expected in the second half of 2017 due to improved efficiency on the project.

Woodside on Thursday added that Persephone development is on budget and that reservoir drilling and completions campaign were finished with subsea installation activities underway.

“At the end of the quarter, progress was 89.8 percent complete versus 84.2 percent planned,” Woodside said.

The A$1.2 billion ($916 million) Persephone Project, approved in 2014, consists of two wells tied into a subsea production manifold via a seven-kilometer subsea tie-back with production fluids transported to the existing North Rankin Complex (NRC), part of the large North West Shelf project.

The Persephone gas field is located in offshore petroleum production license WA-1-L, some 135 kilometers, northwest of Karratha, Western Australia, in a water depth of about 126 meters. The field was discovered in 2006 by the exploration well Persephone-1, which is located approximately 8 kilometers north-east of the North West Shelf Project’s North Rankin Complex.

The North Rankin Complex, which will take gas from the Persephone, is a single integrated facility comprising the interconnected North Rankin A (NRA) and North Rankin B (NRB) platforms and associated subsea infrastructure, including two export trunklines which run between NRC and the onshore Karratha Gas Plant (KGP).
