Abstract
A suite of crude oils from the Shengli oilfield in northwestern China was subjected to detailed chemical analysis. Crude oils in this suite, believed to be derived from source rocks deposited under fresh, brack ish and saline environments have chemical compositions and biological marker compounds indicative of immature source rocks. In this respect the crude oils are unusual, apparently having been formed and expelled from source rocks that have been subjected only to mild thermal stres s prior to the main zone of petroleum generation.
