LOS ANGELES, Jan. 25 -- ExxonMobil Corp. and Chevron Corp. signed agreements, valued at $4.7 billion, to supply natural gas to several Indonesian firms.

Under its agreements, valued at $1.4 billion and $1.7 billion respectively, ExxonMobil will supply gas from Cepu block to fertilizer and related products giant PT Petrokimia Gresik and to the state electic power company PT PLN.

For its part, Chevron will supply gas valued at $1.6 billion from its East Kalimantan fields to fertilizer producer PT Pupuk Kaltim.

Earlier this week, Chevron said it was reviewing its business plans in Indonesia, but remains committed to developing natural gas fields offshore from East Kalimantan.

 "We are currently reviewing our business plans as part of our normal business planning process and in light of changes in the business environment," said Chevron spokesman Gareth Johnstone.

"That said, we are committed to developing the deepwater projects in the Kutei basin. We look forward to working in partnership with the government of Indonesia and BPMigas in developing these fields," Johnstone added.

Meanwhile, the new gas supply agreements with Chevron and ExxonMobil reflect a change in policy for the Indonesian government, which is requiring stronger commitments from international oil companies in the country to make part of their production available to the domestic market.
