Abstract
ABSTRACT
This study was conducted in Kuang area, South
Sumatra Basin, where three oil fields: Air Serdang,
Mandala, and Kuang are situated. The Kuang area is
surrounded by five sub basins (Cintamani, Jantung,
Tanjung Miring, Meraksa, and Lematang).
Talangakar Formation has been known as a source
rock in the area, however the characteristics of the
formation is different in each sub basin. It is therefore
necessary to find out the most possible sub basin(s)
that may be the source of hydrocarbons.
Forty two sediment (cuttings) and fifteen crude oil
samples have been geochemically analyzed. The
basic source rock analysis comprised of screening,
kerogen typing, and maturation. Further analysis,
such as correlation between source rock and crude oil
as well as crude oil to crude oil, has been done by
using more sophisticated techniques, i.e. carbon
isotope and biomarkers.
Based on the geochemistry analysis above, it is
indicated that:
Characteristics of the Lemat and Talangakar
Formations in Tanjung Miring and Cintamani
Subbasins basically show a fluvio-deltaic
characters with a slight different: more oxic in
Cintamani rather than in Tanjung Miring
Subbasin.
Source rocks of Lemat and Talangakar
Formations in Lematang Subbasin are
interpreted to have shallow marine characters.
Crude oils in Kuang area shows the fluviodeltaic
characteristic.
The result of correlation shows that crude oils in
Kuang area were most probably derived from source
rocks of the Lemat and Talangakar Formations in
Tanjung Miring Subbasin.
