Integrated palynological, organic geochemical, and sequence stratigraphic analyses of the middle to upper Cenomanian hydrocarbon reservoir/source Abu Roash 'G' Member: A depositional model in northwestern Egypt

摘要

The current investigation provides further insight into the petroliferous characteristics of the Abu Roash "G" Member, which is regarded as an important rock unit for the Egyptian oil industry. Forty-seven samples covering the "G" Member were selected from the BED 14-1 and BED 2-4 wells in the Abu Gharadig Basin and from the Abu Tunis IX well in the Matruh Basin, both of which are located in the north Western Desert. An independent dating of the "G" rocks of BED 2-4 by benthic foraminifera and ostracods, in addition to palynological dating, suggests a middle-late Cenomanian age and provides the biochronostratigraphic framework for the sequence stratigraphic analysis.
