Each chapter of the report will include a brief text. The main focus of interpretation is a comparison of various phenomena at sheared versus extensional margin segments. Sample descriptions will be included in the report Appendix.
Oil discoveries such as the Jubilee Field located in the Equatorial Atlantic have encouraged exploration in sheared margins worldwide. Sheared margins have a thermal history, which is different from that of extensional margins. Recent studies by EGI in the Equatorial Atlantic and Indian sheared margins have indicated that a successful exploration program in this setting requires a detailed understanding of the thermal and structural history of continental break-up.
Objectives of this project are to refine the existing general timing of break-up for large margin segments with detailed break-up propagation timing, associated distinct vertical movement histories of different margin segments, and attempt to address associated depositional histories of individual margin segments.
EGI will undertake a robust analytical research program with both well samples and dredge samples and interpretation of existing data, focused on:
This effort will be undertaken in context with a re-interpretation of existing open-file geological and geophysical data.
Project sponsors and participants will be updated regularly regarding analyses and interpretations. Three project meetings will be held to assess progress and provide guidance (project kick-off, mid-term and final meetings). The project kick-off meeting took place February 10–11, 2014 in Perth, Australia.
A written Final Project Report will be delivered to Sponsors at the completion of the Project.
