Abstract

Carbon Dioxide flooding have been applied in many oil field reservoirs to enhance oil recovery. The used of CO2 to enhanced oil recovery historically focused on supercritical CO2 to achieve miscible conditions with crude oil. However, one of the major problems agreed is early breakthrough attributed to the unfavorable mobility of CO2 in the reservoir. The objective of this study is to investigate volume of oil recovery by injecting liquid CO2 into the residual oil in place in a core sample. This study occupied 3 fresh Berea Sandstone core plugs and one of Malaysian basin crude oil. Oil recovery was produced by laboratory core flooding experiment. The core was displaced with crude oil after initial brine saturation. Water flood was then initiated by injecting 10,000 ppm concentration of brine water. Oil recovery by water floods were various from 36.6% until 38% after introducing 9 PV of brine. Prior to tertiary recovery, the liquid CO2 was injected at 1200 psig and 1500 psig and several constant temperatures of 20°C, 12°C, and 5°C. In the end, the liquid CO2 was injected and the produced oil was collected. The result of this study gave an interesting oil recovery from 43% to 73.4%.
