PGN Gas Tariffs vs. Oil Price • Fuel oil price by average has increased 126% in October 2005, US$/MMBTU 20.00 hence, has created a stimulus to utilize more natural gas

• High international oil prices (above 16.00 US$60/bbl) increased the burden on 14.49 the Government to keep the subsidy in 12.95 place 12.00 11.96 10.73

Government emphasize on increasing • 8.00 gas usage: Reduce oil subsidy » 5.00 » Increase revenue from oil export 4.00 » Environmental benefits (Blue Sky Policy) 0.00 Jan-02 Jul-02 Jan-03 Jul-03 Jan-04 Jul-04 Jan-05 Jul-05 Jan-06

17 CNGCNG && LNGLNG TransportationTransportation ModesModes

CNG on Barge Transportation • CNG and Mini LNG technologies is utilized to penetrate market that has lower gas demand • CNG on Barge utilized cylinder that is developed from carbon fiber composite reinforcement (CFCR)

Mini LNG Marine Transportation • Mini LNG utilizes conventional LNG technology that has been modified for small scale transportation • Potential gas sources include Donggi, Matindok, Bontang & Makapan • Potential markets include , Bali, East Java & Ambon • Estimated economical capacity:150 – 250 mmscfd

CNG Inland Transportation

• CNG Inland Transportation utilizes truck or train to transport gas in CNG form from city to another. • CNG Inland is utilized to transport gas to refueling natural gas stations located in Java

• GTH technology is developed for storage and natural gas transportation, especially for “stranded gas” from marginal gas fields in • “Stranded gas” is gas reserves geographically located “Gas hydrate is a far from the transmission pipelines or the volume is mixture of gas and excessively low to be transported with pipelines or LNG water that is trapped inside the molecule technology of water” • The conversion from gas to hydrate results in volume compression of 150 to 180 times which is viable to be transported • Feasibility study shows that GTH technolgy for long- distance transportation is 25 percent cheaper than LNG technology
