Abstract:
Petroleumgeochemistry is an application of chemical principles to study the origin,
migration and accumulation of petroleum and its use in exploring and obtaining
petroleum. The oil wells originating from Bakau and Beruk are oil wells that have
recently been discovered and there is no molecular gheochemical study yet. Samples from
oil wells Bakau and Beruk were fractionated by chromatography column into aromat
fractions then analyzed for biomarker compounds using gas chromathography-mass
spectroscopy (GC-MS) m/z 191. Based on the ratio hopana petroleum from Bakau
(0,63) and Beruk (0,50) and the level of maturity is early mature. Determination of the
origin of organic material using the parameters oleonana in Bakau and Beruk oil (1,72
and 1,04) indicates from organic matter of land plants (angiospermae). Bakau and
Beruk peroleum re in the depostional environment with non hypersalin content as
evidenced by the parameters of gammaserana in the Bakau and Beruk petroleum (0,10
and 0,48). Correlation studies with start chart show that oil from Bakau and Beruk
petroleum is negatively correlated.
