Why is it important?
Our findings are: 1. Most rock Kerogen is type II, good possibility to generate and expel liquid hydrocarbons in the mature case more than Kerogen Type III. 2. In the Carboniferous and Devonian Formations, the Tmax illustrated that most of the samples dropped inside the mature region and potential yields exceed 2000 ppm, as sign to immature / mature organic matter. 3. A regional study of the three fields has been carried out that the Hot Shale Member (Lower Silurian) at the base of the Tanezzuft Formation is a high quality, oil level source rock which is currently at oil maturity and has not yet gone in the gas window. 4. Overall average TOC content of the Hot Shale Member is high with a maximum recorded value of 16.7%. 5. Vitrinite Reflectance (% Ro) and Spore colouration (SCI) of the Hot Shale Member ranges from 0.57% to 0.85% and 7.0-8.5 respectively, indicted higher than others. 6. Aromatic hydrocarbon ratios revealed two levels of thermal maturity, the Hot shale member showed high aromatic content, revealed stage of thermal maturity while rest sediments have low aromatic hydrocarbon reflected marginal thermal maturity.
Perspectives
The purpose of this paper is to describe lithology of studied formations, TOC analysis, rock pyrolysis, organic matter reflectivity, spore colouration and aromatic molecular biomarker as geochemical parameters to establish kerogen type, potential yield and thermal maturity.
