The South Sumatra Basin is one most prolific hydrocarbon provinces in Indonesia (Figure 1) with estimated known petroleum resources of 4.3 billion barrels of oil equivalent (bboe) (Klett et al., 1997). Talang Akar Formation (TAF) is the main source and reservoir rock in the basin (Sarjono and Sardjito, 1989; Sosrowidjojo et al., 1994). It accounts for more than 75% of the cumulative oil production in the province and has approximately 2 bboe ultimate recoverable reserves (Tamtomo et al., 1997). The late Oligocene to early Miocene TAF is up to 610m (thick Hutchinson, 1996) and was deposited under various environments, which include open marine, nearshore, delta plain, delta, distributary channel, fluvial, and beach (Hutapea, 1981).
