The Lobe Phase 2 Joint Industry Project; supported by 16 companies, started in May 2012. The project builds upon the results and experience of Phase 1, which focused on developing models for the depositional architecture and stratigraphic evolution of submarine lobe deposits based on field and core data in the Karoo Basin South Africa. Complementary process-based numerical models tested hypotheses of conceptual models developed from outcrop investigations. A new predictive understanding of lobe hierarchy has demonstrated that lobe volume is independent of supply system size. A 530m-deep research borehole (BAV1b) was fully cored through Units A and B.
The objectives of Lobe Phase 2 are:
- to better understand the stratigraphic architecture and process record near channel mouths
- to characterise the full variety of lobes in different geographic and stratigraphic settings
- to quantify the range and distribution of hybrid bed types (and key permeability controls)
- to apply generic concepts to subsurface datasets
- To understand lobe architecture and stratigraphic record in post-rift settings
The Lobe Phase 2 Project will still have a big focus on the Karoo basin (South Africa), but will extend its working field to the Neuquen basin in Argentina.
