Initial Screening Study of CO2/EOR
- Initial CO2 EOR/CCS Screening Study was completed. The study was
screening of oil fields in South Sumatera Basin of 100km radius of SNG
plant.
- The study collected data of half of oil fields in the radius. 2/3 of
reservoirs show CO2/EOR miscible flooding.
- Detail study for CO2/EOR for one representative reservoir was
conducted. The study of core sampling, slim tube test and geologicalsimulation was carried out. Increment oil recovery is estimated to be
28.8%.

4. Feasibility Study Summary
The product price of SNG is 10 $/MMBtu calculated by sensitiveanalysis. This price is equivalent to import LNG CIF price.
Coal gasification test was completed successfully. Slag was discharged
very stable. No unburned carbon fell down from slag hole. Initial CO2 EOR/CCS Screening Study around the potential low rank coal
mine was completed. The study was screening of oil fields in SouthSumatra Basin of 100km radius of SNG Plant. The study collected dataof half of oil fields in the radius. 2/3 of reservoirs show CO2 /EOR
miscible flooding. The reduction potential volume of CO2 was calculated and the
methodology of CO2 reduction for Indonesia SNG/EOR plant wassummarized. Possible CO2 Reduction volume in this plant will be about6.29 M t/y.
