The Santos Ltd.-Tamboran Resources Ltd. joint venture in Beetaloo basin permit EP161 onshore Northern Territory, Australia, has increased its estimated 2C contingent gas resource by 164% following a review of extended production test data from the Tanumbirini-2H and 3H appraisal wells.
The upgrade of unrisked 2C contingent gas resources has risen to 1.617 tcf while the unrisked 1C contingent resource has increased by 73% to 330 bcf.
The upgrade also incorporates additional data supporting the reservoir continuity of the Mid-Velkerri C Shale reservoir and an updated development strategy that includes drilling 3,000 m horizontal wells, Tamboran said.
The upgrade has been evaluated and certified by Netherland, Sewell & Associates Inc.
The area over which the 2C resources have been booked covers less than 4% of the prospective acreage within the permit, the company said.
Santos is operator of the license with 75% interest. Tamboran holds 25% interest.
