| description | Talang Akar Formation is one of the formation that act as source rock of South Sumatera Basin
which is known as a prominent oil producing basin in Indonesia. This study discuss the
geochemical characteristics by means of Rock Eval Pyrolysis method and organic petrography
of shale taken from outcrops of Talang Akar Formation in Lahat and Pangkalan Balai.
The result of Rock Eval Pyrolysis analysis show that TOC values range from 0.94 %-4.33 %,
the value of HI range from 45 -235 mgHC /g TOC , OI 4-97 mgCO2 / g TOC , vitrinite
reflectance ( Ro ) 0.2%-0.48 % , and Tmax 426

C. Geochemistry data from Pangkalan
Balai area show that this shale is still immature but has good potential to be source rock, with
expected dominant product of gas. Whereas Lahat geochemistry data show fair potential to be
source rock, oil as dominant product with level of maturity is mature. Meanwhile, based on
organic petrography analysis show that both in Pangkalan Balai and Lahat area are dominated
by liptinit maceral.
