Flood Basalt Impact on Hydrocarbon Systems Project 2019-2021
Hydrocarbon exploration has increasingly moved into volcanic basins, where intra-volcanic discoveries have been made. Through analogue studies, this project will address the many uncertainties that still remain concerning lava field sedimentation, reservoir architectures and properties, and the effects of volcanism on sub-volcanic sedimentary sections. In addition to addressing these generic uncertainties, this phase will also have specific relevance for those exploring along the East African Rift.
Main Objectives
- Constrain the depositional history of the volcanically affected Blue Nile Basin to aid comparisons to other East African lacustrine basins.
- Understand the impact of volcanism on the provenance of sub- and intra-volcanic sandstones of the Northwestern Highlands, Ethiopia.
- Investigate the impact of shield volcanoes on drainage pathways.
- Characterise magnetic susceptibilities through heterogeneous volcanic sequences.
- Elucidate the impact of volcanic debris on the diagenesis, reservoir properties and sealing capacities of sandstones.
Project Length: 24 months from February 2019.
