Characterising Fractured Basement Reservoirs

4th EAGE Workshop on Naturally Fractured Reservoirs, Ras Al Khaimah, UAE, February 2020.

Following the recent discovery that the storage and flow capacity of some basement reservoirs relates to both fracture and fissure capacity, we are working towards further understanding as to how and when this paradigm shift should be applied. Our current model is based upon observations from the Rona Ridge in the UK West of Shetland. Critical questions to be addressed include: How applicable is the fissure model to other basement plays (and tight cover sequences) globally? What are the relative contributions of the fractures and fissures to storage and flow, how do they inter-relate, how can they be adequately described and how might we expect the contributions to vary in different settings?
