Abstract
Prediction and modelling of subsurface geothermal reservoir properties without knowledge of the diagenesis are unconfident. Diagenesis controls both matrix porosity / permeability and mechanical rock properties by cementation and leaching processes. Simultaneously occurring with (brittle) deformation, diagenesis can also influence fracture formation. Here an integrated approach to the characterisation of geothermal reservoirs with focus on diagenesis is presented.
