Abstract

This research was studied about the correlation bettwen Duri oil well (GL-47) with Bangko well (PN-026). The Bangko well (PN-026) and Duri well (GL-47) had a negative correlation, with was evidenced by parameter biomarkers using Aromat fraction by means of GC-MS at m/z 191 based on terpenoid compounds contained. This study used 10 parameters, so it was obtained sample well Bangko (PN-026) that has a mix of depositional environments and more is known as lacustrine oleanane with ratio value of 3,083 and a slight mix-terrigeneous delta and terrestrial environments that were affected by salinity. Sample Duri well Km 7 (GI-47) has a mix of depositional environment dominated by terrestrial that can be seen from the value of the ratio C25 / C26 Tricyclic at 1,125. Bangko sample has a level of maturity "mature" with a ratio value of 0,75, while Duri sample has the level of maturity "early mature" with a ratio value of 0,75.
