Mubadala Petroleum started production Tuesday at its Manora oil field in the northern Gulf of Thailand.
Proved and probable reserves contained in Manora’s primary reservoir, and recoverable by natural depletion, are estimated to be about 20 million barrels gross.
Production is expected to reach a peak rate of 15,000 barrels of oil per day as more production wells are completed.
Up to 10 production wells and five injection wells in the main reservoir sequence are planned.
The project is located in in the G1/48 concession, about 49 miles offshore in waters depth of 144 feet.
The field is projected to have a commercial life in excess of 10 years.
Abu Dhabi-based Mubadala said water injection will be implemented from start-up and, once its effectiveness has been confirmed by enhanced production performance, further reserves will be added.
Originally discovered in 2009, Manora opened up a new oil play in the northern Gulf of Thailand.
The field was appraised by drilling three wells and field development was sanctioned in July 2012.
Facilities at the site include a wellhead processing platform, with water injection facilities to maximize oil recovery, connected via subsea pipelines to a floating storage and offloading vessel.
Mubadala is also developing the the Nong Yao oil discovery in concession G11/48 with first oil expected by the middle of 2015.
“The Manora development builds on Mubadala Petroleum’s strong technical understanding of the subsurface in this basin, which is based on the experience gained over the years in the very successful operation of the Jasmine oil field in concession B5/27,” Mubadala COO Bakheet Al Katheeri said.
State owned Mubadala Petroleum holds a 60 percent operating interest in G1/48.
Thailand-based Tap Energy holds a 30 percent interest and Thailand-based Northern Gulf Petroleum holds a 10 percent interest.
