Fractured Carbonates 

Fracture analysis of analogue limestone/dolomite reservoirs

Appraisal and development of fractured reservoirs including carbonates remains a significant challenge because the generally high degree of heterogeneity in the intensity, distribution and connectivity of the open fracture system. This course uses analogue outcrops and classroom sessions to equip the geothermal or oil industry geoscientist and reservoir engineer with the essential knowledge from structural geology, fracture characterisation and rock mechanics to work with fractured carbonates. See the related paper: Fracture analysis of outcrop analogues to support modelling of the subseismic domain in carbonate reservoirs, south-central Pyrenees, by Gutmanis et al., 2018, Geological Society.
