Santos Builds Position in Southeast Asia

Santos announced its first entry into Vietnam with an agreement to farm in to offshore exploration acreage operated by UK-based Premier Oil.

Under the agreement, Santos will hold a 37.5% interest in Blocks 12E and 12W Production Sharing Contracts after funding a proportion of the costs of a two-well drilling program. The blocks cover approximately 5,160 square kilometers in the Nam Con Son Basin, offshore southern Vietnam.

The two-well drilling work program includes the Dua-4X well and the 12-CS-1X Blackbird well in Block 12E. The first well, Dua-4X, is scheduled to commence drilling in early May 2006 immediately followed by Blackbird.

Santos' move into Vietnam is in line with the Company's strategy to diversify its international operations through a focus on material positions in proven hydrocarbon basins. The Company is also currently assessing other opportunities to increase its exposure in Vietnam.

"This is an important step for Santos as we continue to broaden and build our international exploration interests," Santos Managing Director, Mr. John Ellice-Flint, said today.

"The Nam Con Son Basin is a proven hydrocarbon province and we are pleased to be teaming up with an established operator with excellent regional experience," he said. "The drilling program will commence immediately. Importantly the targets are close to production facilities and in shallow water which will help shorten the development cycle-time in the event of a discovery."

The interests in Blocks 12E and 12W are:

Post farm-in: Santos with 37.5%; Premier as operator with 37.5% and Delek Energy with 255; Pre farm-in: Premier as operator with 75% and Delek Energy with 25%.
