The Anoa Field marks the entryof Amoseas Indonesia Incorporated into the ranks of Indonesian oil producers. The field is located in t.he Natuna Sea Block 'A' Production Sharing Contract (PSC) Area, almost 700 miles [1,120 km] north of Jakarta on the Indonesian - Malaysian border. The structure was discovered by AGIP in 1974. A small oil accumulation within the field was discovered and delineated in 1982. Commerciality was granted for development of the oil accumulation in 1985. The field came on production in late 1990. Amoseas is the operator of the PSC on behalf of Pertamina, Sumatra Gulf Oil Limited (a Chevron Corporation subsidiary), and the Kuwait Foreign Petroleum Exploration Company (KUFPEC). Amoseas is a member of the Caltex group of companies, a 50 - 50 joint venture of Chevron and Texaco Incorporated.This small, remote field presented many challenges. This paper will highlight the technology used to successfully develop the field. Topics reviewed include: the use of 3-D seismic for reservoir description and development planning, use of reservoir simulation models in development planning, the innovative approach to field facilities utilizing a 4-pile platform and floating production, storage, and offloading (FPSO) barge, the state of the art drilling technology, and the reservoir management planning.
