Basin Evolution and Geochemical Modeling
Implications for the Palaeozoic and Mesozoic hydrocarbon potential using fission track analysis in the Berkine and Murzuq basins
Postdoctoral research by Dr Henning Kocks and Dr Sebastian Lunging
Objective:
To demonstrate the value, applicability and technical feasibility of apatite fission track studies (AFTA) for petroleum exploration in the Berkine, Illizi and Murzuq basins using outcrop and downhole samples. To evaluate the possibility of initiating a regional study to identify the extent and significance of Hercynian and Alpine deformation for petroleum systems across North Africa.
Method & Strategy:
- Review of the current understanding of Alpine uplift across N-Africa using published literature and AFTA data to devise a framework for this project.
- Evaluation of samples available and production of three to four profiles across which we will carry out fission track analysis. The rocks will be Cambrian to Tertiary in age and - where possible originating from above and below major stratigraphic breaks.
- We will complement available sample material with surface samples that we hope to collect on field trip to Algeria and Libya early in 2003.
- We further aim to develop and establish new contacts with resident oil companies and national research organisations and government bodies to devise a joint venture scheme that will allow us further access to sample material and knowledge transfer to the respective company.
Deliverables:
- Synthesis report on the current understanding of Saharan uplift history, including a review of currently available AFTA data across N-Africa.
- Presentation of AFTA data produced by that stage and its implications.
- Status report on sample availability (present and future) and possible joint projects with Sonatrach / NOC.
- Outline of future strategy leading to a regional AFTA database across N-Africa.
Results:
The project demonstrated the feasibility of future AFTA work, and demonstrated the implications that saharan uplift had on the hydrocarbon potential of the region. A large amount of AFTA results were attained and this stands the study in good stead for the future.
