RCMA Australia has identified four new leads within the L14 licence, which contains the Jingemia oilfield, in Western Australia’s onshore Perth basin.

Joint venture partner Norwest Energy revealed Monday an independent technical review by Leap Energy had identified four target prospects and four target leads within the permit.

The four prospects include Black Grove, Agile, Agile West and Tammar which are estimated to hold a combined best estimate prospective resource of 20 million barrels.

The target leads include Yellow Foot, Black Flanked, Nabarlek and Western Bush which have a combined deterministic estimate of 327.9 million barrels.

Norwest noted that the prospects and leads were in close proximity to existing infrastructure associated with the producing Jingemia oilfield, adding the Jingemia facility had excess capacity.

“This is the first time the L14 production licence has undergone remodelling since prior to 2012, when the field was shut in,” Norwest chief executive Shelley Robertson said.

“Leal Energy’s new analysis has enabled the joint venture to take a fresh look at the L14 prospectivity, and so far we like what we see.”

The joint venture will now carry out more work to further refine the prospects and leads while also looking at ways to fund and drill a multi-well programme.

Norwest said RCMA had advised it was seeking “third party investment” for the L14 licence area ahead of a planned two-to-six well drilling programme in the third quarter of the year.

RCMA currently operates L14 with a 93.722% interest and Norwest holds the remaining 6.278% equity.
