Abstract
- The biomarker composition of biodegraded petroleum in an oil seep was determined using GC and GC–MS techniques. The results show that many important biomarker compounds are eliminated or highly altered by biodegradation. In order to establish a correlation between the seep sample and a non-biodegraded crude oil sample from the Dhurnal field, asphaltenes were isolated from the seep and subjected to hydrous pyrolysis. The biomarker composition of the pyrolysate and the Dhurnal oil is similar, suggesting that they are generated by similar source rocks.
