Australia-based Carnarvon Petroleum Limited (Carnarvon) provided the following update Friday in relation to the L44/43 and L33/43 Concessions in Thailand, in which Carnarvon holds a 40 percent interest.
As of Nov. 15, the rig is on site and rig up is in the last steps of completion and inspection, with spudding of the first well planned to commence in the next few days.
The first well in this campaign is the WBEXT-2BST2 sidetrack well, a deviated appraisal/development well in the WBEXT area, being updip from an existing oil production well.
The primary objective for the WBEXT-2BST2 is to test the productive igneous V2 reservoir. This reservoir is estimated to be 164 feet (50 meters) thick at the target location.
The well is targeting a location in the same reservoir as the recently completed WBEXT-2C well, which initially flowed up to 400 barrels per day of oil and 1,000 barrels per day of water. This well has produced over 15,500 barrels of oil to date at continued high water cut.
The target location for WBEXT-2BST2 is 49 feet (15 meters) updip of the igneous V2, in order to be further from potential water zone, and closer to the main fault, which is interpreted to be a better location for fracture development.
Secondary targets are the igneous V1 reservoir, which was encountered in WBEXT-2C well at around 32 feet (10 meters) thick with good oil shows but has not yet been tested. Shallower sandstones zones are also expected to be intersected.
The well has a projected total measured depth of around 4,593 feet (1,400 meters), with the Wichian Buri II igneous interval being interpreted at 3,116 feet, or 950 meters (true vertical depth).
Following on from the drilling of this well the joint venture will drill further wells in the WBEXT production area targetting development locations within the reserves areas.
Further near term development and exploration wells are planned within the recently acquired L33/43 3D seismic area.
