Jintan

Location

The Jintan oil and gas field is situated offshore in the Sarawak region of Malaysia, specifically within blocks SK8 and SK10.

Operators and Stakeholders

The project involves several key stakeholders:

• Occidental and Nippon Oil are the primary operators of the gas discoveries in block SK8.
• Sarawak Shell and Petronas Carigali are also major stakeholders, with Shell bringing significant LNG operating expertise and commercial clout to the project.

Field Discoveries

Several gas discoveries have been made in the area:

• Jintan-1, discovered in 1992, is one of the first and most significant finds, located in Miocene reef carbonates.
• Other discoveries include Selasih-1, Serai-1, and Cili Padi-1, all made in 1993.
• Additional discoveries include Saderi-1 and Helang-1, with Helang-1 being Nippon Oil's solitary commercial discovery in block SK10.

Development Plan

The development of the Jintan field is planned in phases:

• The initial phase involves the development of Jintan's gas via a central processing and living quarters platform linked to a drilling/wellhead platform.
• Saderi and Serai fields are expected to be tied in as subsea completions, with a new trunkline carrying processed gas to the Bintulu LNG complex.
• In the second phase, production platforms will be installed on Cili Padi and Selasih fields, also linked to the new pipeline. Helang field will require a separate trunkline to Bintulu.

Infrastructure and Capacity

The project is integrated with the Malaysian LNG (MLNG) Tiga project:

• The MLNG Tiga project includes a new LNG plant near the existing MLNG complex at Bintulu, with an initial capacity of two trains processing up to 6.6 million tonnes per year.
• The first shipments from the new plant were expected to begin in 2000, with production building up to 900 million cubic feet per day by 2004.
• The Bintulu complex, including MLNG Dua and Tiga, is expected to become one of the world's largest LNG complexes, capable of exporting nearly 23 million tonnes per year.

Reserves and Production

Wood Mackenzie estimates the reserves in the fields allocated to the project at 6.2 trillion cubic feet (tcf), with 5.2 tcf located in fields discovered by Occidental in block SK8. The Helang field is estimated to have reserves of about 1 tcf.

Market and Contracts

Much of the LNG produced from this project is contracted on long-term agreements, primarily to utilities in Japan, Korea, and Taiwan.
