Thursday, June 23 2011 - 03:42 AM WIB
Rig#88 Skytop Brewster is rigged up on location at Pase A-2 and pressure testing has been completed. All support services are also on location. Work-over operations commenced on Wednesday 22 June, the company said.
Immediate operations include drilling out temporary cement plugs from Pase A-2 to total depth.
Pase A-2 was drilled as an appraisal well by Mobil in 1984 but was never produced. Three Drill Stem Tests (DSTs) were successfully conducted and a maximum rate of 23.9 MMcf/d was recorded during DST#3A (maximum flow rate for a Hydrospring FulFlo Valve testing tool), a comingled Peutu/Belumai test (no cement). Additionally, the Bruksah sandstone flowed a maximum rate of 22.5 MMcf/d.
Following the work-over of A-2 the rig will be moved 4.2 km to Pase A-1 to remove a blockage inside the existing 7? production string, providing access to an additional 442 feet of lower reservoir, it said.
Pase block contract will expire in 2012. The block was acquired by Triangle from Exxon Mobil in 2009. (romel)
