Malaysia's state-owned Petronas expects the Angsi oil field in the South China Sea to produce 65,000 b/d of oil and 450-mil cu ft/day of natural gas at its peak, the company announced. The oil field started production on Dec 21, six months ahead of schedule, at an initial rate of 15,000 b/d and 60,000 mcf/day. The peak volumes would be equivalent to 10% and 17% respectively of the country's current total oil and gas production, Petronas said. The Angsi field is jointly developed by Petronas Carigali, and ExxonMobil Exploration and Production Malaysia Inc. The Angsi project began in late 1997 under a new Gas Production Sharing Contract signed in the middle of that year. Petronas Carigali and ExxonMobil are 50:50 partners, with the former operating the field.
The Angsi project comprises an integrated oil and gas central processing platform connected to a 52-well drilling platform via a 100-meter bridge, as well as a 32-well satellite drilling platform, Petronas said. The complex is the biggest integrated oil and gas platforms in the South China Sea, the company noted. Over 300 km of pipelines were installed by the partners as part of the development of the Angsi field, including connections to existing gas production facilities at Guntong-D and Seligi-A, connection to the existing oil production facilities at Tapis and a new 166-km pipeline from the Angsi complex to the onshore receiving facility.
