Advances in Fault Zone Structure and Property Prediction: Applications to Reservoir Geomechanics
Recorded On: 09/09/2021
Faults at many scales impact fluid flow in producing hydrocarbon fields, and focus deformation due to fluid pressure changes, potentially causing overburden leakage and induced seismicity in the reservoir, overburden, or underlying basement. This seminar firstly reviews how the petrophysical and mechanical properties of fault zones control their response to reservoir pressure changes during production (depletion, injection), and consequently their geomechanical behaviour in terms of fault stability. Advances in our understanding of fault zone structure and properties in the last decade are then discussed and shown to have led to more consistent fault zone property estimates. Applications to different case studies of field development are then presented, specifically for analysing the stability of overpressured trap-bounding faults during depletion, leakage and fault stability in the overburden during reservoir injection, and conduit behaviour conducting injected fluids from reservoir to basement and consequent induced seismicity. Finally, future ways forward for predicting fault-related leakage are considered, in terms of the present tectonic context and past geological history of the faulted reservoir and overburden.

Dr. Christopher Wibberley
Senior Technical Advisor, TotalEnergies
Dr. Christopher Wibberley is a senior technical advisor at TotalEnergies, France, specializing in structural geology, hydrodynamics and seals. After studying geology at Oxford (B.A. degree), and Leeds (Ph.D. in basement tectonics, 1995), Chris held university research positions at Montpellier, Kyoto and Cambridge (CASP) until moving again to France where he obtained his senior research habilitation as a university lecturer in Nice – Sophia Antipolis before moving to Total in 2007. Chris has progressed through various positions both in Total’s headquarters providing specialist technical support for projects, and in the Total EP Congo affiliate as an exploration geologist. He now performs a role of technical advisor to a wide variety of exploration, reservoir development, CCS and R&D projects.
His research aims to improve quantification and prediction of fluid flow and geomechanical behaviour of faults and fracture systems in the Earth’s crust, applying this research from petroleum E&P to seal integrity in CCS, induced seismicity and understanding tectonic processes.
