• Kangean PSC acquired by EMP from BP in August 2004• Terang field discovered in 1982, Sirasun in 1993 and Batur in

1995• The TSB reserves of 1.6 TCF were certif ied by “ D&M” in May

1995• Kangean PSC Extension approved in December 2004• Development of TSB fields i s expected to deliver gas to East

Java market starting from 4 th Q 2007• Development strategy: Phase-1 with target of production in

4 th Q 2007 and Phase-2 with target of production in the 4 th Q2009.

• Plan Of Development (POD) approved in October 2005• Front End Engineering Design completed in October 2005
