Description

"The West Seno Project and Unocal’s Developments in Southeast Asia"

The West Seno project is the first of a growing inventory of significant developments moving toward commercialization to fuel Unocal’s near- and medium-term growth.  West Seno is the first deepwater oil and gas project in Indonesia with first oil in August, 2003.  Daily production is expected to peak at 60,000 barrels of oil and 150 million cubic feet of gas per day by year-end 2005 with the completion of Phase 2. Ultimate recovery is 210 to 320 million barrels of oil-equivalent.

Unocal Makassar operates the PSC and has a 90-percent working interest.  Pertamina Upstream, a unit of the state-owned oil and gas company, holds the remaining interest.  Unocal Makassar is developing West Seno in two phases with two tension leg platforms (TLP) and a floating production unit (FPU). Phase 1 includes 28 development wells to recover resources in the northern section of the West Seno field. The TLP supports the 28 development wells and a tender-assist drilling rig. This is the first application of a tender-assist drilling rig in a deepwater environment. The TLP is linked to the nearby FPU where the produced oil and gas is processed to sales quality.

Phase 2 will include a second TLP and up to 24 additional development wells on the field’s southern section. Production from Phase 2 is expected to begin in 2005. West Seno, located in the Makassar Strait production sharing contract (PSC) area, was discovered by Unocal in 1998. The field lies about 118 miles northeast of Balikpapan in water depths of approximately 3,200 feet.

West Seno is just the first of Unocal’s inventory of growth projects in Southeast Asia that include Ranggas and Merah Besar oil and gas developments in deepwater Indonesia; Arthit gas development in Thailand; Xihu Trough gas development and exploration in China; and Moulavi Bazar gas field development in Bangladesh. These growth projects are all in addition to the other natural gas resources the company has discov
