PT Caltex Pacific Indonesia has extended its production sharing agreement with Indonesia's Pertamina covering the Rokan block in Central Sumatra for 20 years to 2021.

The 9,898 sq km contract area (see map, OGJ, June 10, 1991, p. 15) includes Indonesia's two largest producing fields, Minas and Duri.

Caltex, jointly owned by Texaco Inc. and Chevron Corp., is a contractor to Pertamina and produces 700,000 b/d of oil from four contract areas in Central Sumatra. More than 600 000 b/d of that comes from the Rokan block.

The new agreement includes a work program that provides for continued exploration on the block and expansion of enhanced oil recovery programs.

Minas, largest oil field in Southeast Asia, has produced more than 3.6 billion bbl of crude since production began in 1952. Caltex started peripheral waterflooding at Minas in 1970, and a patterned waterflood is to begin late in 1993.

Duri is site of the world's largest steamflood. The project began in 1983 and is expected to continue for several decades at a total cost of more than $2 billion. Texaco said Duri steamflooding will enable Caltex to produce more than 50% of the original oil in place.

Texaco said the contract extension will allow access to oil reserves that will produce well beyond the previous contract expiration date of 2001.
