Dallas-based firm Continental Energy Corporation announced Monday that its 18% owned Indonesian subsidiary Continental-GeoPetro (Bengara-II) Ltd. has spudded the Seberaba-3 appraisal well.
The Seberaba-3 is the second of 3 planned appraisal wells to further evaluate the Seberaba structure in the Bengara-II Block, onshore East Kalimantan, Indonesia. Drilling of the Seberaba-3 to a planned total depth of 2,800 meters (9,186 feet) is expected to take up to 49 days at a cost of over US$5.4 million.
The Seberaba-3 will test an updip structural culmination of the large Seberaba structure at a position on the same structure approximately 2.3 kilometers northwest of the Seberaba-1 exploration well location, and approximately 5.0 kilometers northwest of the Seberaba-4 appraisal well location.
The Seberaba-3 appraisal well is being drilled with the same drilling rig used to drill the Seberaba-1 wildcat exploration well.
Drilling on Seberaba-1 was terminated short of the planned 4,000m total depth after having reached a total depth of 2,946m. A 7? liner was set at 2,917m in the third sidetrack after the original hole and first two sidetrack holes were lost due to encountering a zone of overpressure below 2,930m.
A smaller workover rig has been moved onto the Seberaba-1 to conduct a series of drill stem tests.
Other participants in Bengara-II block are Chinese firm CNPC, which holds 70 percent interest and San Fransisco-based GeoPetro Resources with 12 percent interests. (alex)
