Geochemical characteristics of some crude oils from Alif Field in the Marib-Shabowah Basin, and source-related types

The Marib-Shabowah Basin is an important hydrocarbon province in western Yemen, but the origin of hydrocarbons is not fully understood. In this regard, geochemical characteristics are used to provide information on source organic matter input, depositional environment and the correlation between cru...

Description
Summary:The Marib-Shabowah Basin is an important hydrocarbon province in western Yemen, but the origin of hydrocarbons is not fully understood. In this regard, geochemical characteristics are used to provide information on source organic matter input, depositional environment and the correlation between crude oils from different pay zones. Two oil families are present within the study area and classified based on biomarker and non-biomarker parameters. The family I oils are characterized by low API gravity, high sulfur and trace metal (Ni, V) contents and low Ph/Ph ratio
