Salamander Energy has successfully completed Phase IV of development drilling on the Bualuang oil field, Block B8/38, offshore Gulf of Thailand.
The Vantage Emerald Driller jackup rig arrived on location on March 26, 2010, for a drilling program at Bualuang that comprised the side-track of three existing slant production wells and their conversion to horizontal production wells. Following the completion of operations, the rig departed from site on May 10, 2010.
All three sidetracked horizontal wells, BA02 ST2, BA03 ST2 and BA04 ST2 have been completed in the main producing area of the field with downhole electric submersible pumps and expandable sand screens. The wells each consist of 600 to 800 meter horizontal sections, and were successfully landed in the target zone between 3 - 5 meters below the top reservoir.
All three wells have now been brought on stream, having cleaned up and tested at stepped-up rates to determine well productivities. In each case these are at upper end of pre-drill estimates. The wells will be choked back to produce at rates for optimal field management and reserves recovery.
