Abstract
Organic geochemistry methods such as high temperature combustion, Rock-Eval pyrolysis and gas analysis were used to analyze oil shale from Babouri-Figuil Basin. Results show that the average content of organic matter is 36.25 %wt, while that of mineral matter is 63.75 %wt. The total organic carbon (TOC) is between 15.93 %wt and 26.82 %wt. The HI vs. Tmax diagram indicates an immature Type I kerogen. The average value of the oil potential (S2b) is 149.95 mg HC/g rock. The gases obtained by retort process are H2, CO2, CO and CnH2n, CnH2n+2. Finally, it emerges that, the organic matter of Babouri-Figuil shales was immature or has just reached the beginning of the oil window. The mineralogical study of Babouri-Figuil oil shale has been carried out by means of XRD (X-Ray Diffractometry) and XRF (X-Ray Fluorescence spectrometry). The results show that mineral matrix contains silica, carbonates, sulphates, oxides and clay minerals. Besides, compounds contain metals and metalloids like Fe, In, Ca. The main oxides are SiO2 (majority), CaO, Fe2O3, Al2O3, SO3, and K2O.
Highlights
As the overall situation of conventional oil and gas resources becomes increasingly severe, oil shale resources begin to be paid more and more attention
In Cameroon, one of the main deposits of oil shale is localized in the Cretaceous Basin of Babouri-Figuil, North Region, precisely in the Mayo Figuil and Mayo Tafal series
The percentage of mineral and organic matter can be obtained by the high temperature combustion method
Summary
As the overall situation of conventional oil and gas resources becomes increasingly severe, oil shale resources begin to be paid more and more attention. Since oil shale is characterized by beneficial features, economic values and large resources, it is considered as an important substitution resource for the 21st century [1] [2]. In Cameroon, one of the main deposits of oil shale is localized in the Cretaceous Basin of Babouri-Figuil, North Region, precisely in the Mayo Figuil and Mayo Tafal series (or outcrops). Due to the economic and scientific interest of this resource, the Laboratory of Petroleum and Sedimentary Geology of University of Yaounde I—Cameroon has decided to study these oil shale formations. The aim of this study is to give the organic and inorganic composition of Babouri-Figuil oil shale and to characterize their organic matter. All the information has been obtained by high temperature combustion method, Rock-Eval pyrolysis, gas analysis, XRD and XRF
