Summary:
The Chegu20 buried hill reservoir (Cg20) and the Che57 buried hill reservoir (C57) are two high yield fields, located in Chexi sag, Jiyang depression. Oil-source correlation shows that the oil of two buried hill reservoirs are both from the third section of Shahejie formation in Chexi sag, while the oil properties of two buried hill reservoirs are quite different. Analysis of hydrocarbon composition from different buried hills by GC-MS showed that biodegradation may be the cause of differences in their hydrocarbon properties.
