A Probable Connection between a Bitumen Sample from the Western Niger Delta and Isan Well Sample from the Lower Cretaceous (Neocomian) Shale

An earlier study of GC-MS analysis on bitumen samples from the Agbabu area in Western Niger Delta showed significant presence gammacerane and no Oleanane is suggested to be generated Lower Cretaceous (Neocomian) source rock, however, twelve core were obtained geological survey Nigeria for both optical geochemical biomarker analysis, two Isan-9 well indicated Botryococcus braunii a freshwater alga which characteristic lacustrine lake type environment. The extracts same m/z = 191 chromatogram with diagnostic stratified water columns characterizes typical However, also shows vascular plant materials, this doesn’t corroborate that Ise-2 well. rock have occurred due evolving structural geology continental shelf after onset rifting, whereby dominant lake-type environment Early was accompanied by sediment fill runoffs containing materials. This implies an ancient system gradually modified as result sedimentary infill. And sourced lower Neocomian rocks.
