  • Proppant Crushing Mechanisms Under Reservoir Conditions

    Proppant Crushing Mechanisms Under Reservoir Conditions

    Dec 15, 2018 Proppant crushing, a major proppant failure mechanism, occurs in geothermal energy and oilgas stimulation production stages when the level of net stress exerted on the proppant exceeds the actual crush resistance of the material. Loss of effective reservoir conductivity due to proppant crushing can result in significant loss in productivity, and so it is crucial to understand the realistic ...
