Abstract
The interest of this research: there is oil seepage at the contact between coal
seam-A and sandstone facies of Warukin Formation, so it is necessary to study
where is the source rock. The correlation between HI and Tmax as result from
rock eval pyrolysis shows that the shale of the Warukin Formation is immature
while the correlation between HI and OI shows oil prone. The vitrinite (Ro)
reflectance of Central Wara coal is between 0.48% up to 0.5% (immature), the
content of the vitrinite group is 68.0 - 84.8 (% Vol.), Liptinite 3.0 - 14.0 (% Vol.)
and inertinite 0.48 - 25.0 (% Vol.). The high content of liptinite mineral groups
(14% Vol.) and the presence of exsudatinite maceral are as an initial indication
of bitumenization of oil formation when there is a change in reflectance and
fluorescence. Therefore, Central Wara coal plays an important role as the
source rock of the Warukin Formation, although the maturity level is immature, the presence of exsudatinite maceral is believed to be the source of origin
for producing oil, where the organic material comes from terrestrial.
