Compression And Crushing Behavior Of Ceramic Proppants
Abstract Proppants play a pivotal role in hydraulic fracturing treatment for oil and gas production in low-permeability hydrocarbon-bearing formations. This paper experimentally investigates the compression and crushing behavior of engineered ceramic proppants and frac sand. Proppants time-independent and time-dependent mechanical behavior was quantified by conducting displacement-controlled ...
Proppant Crushing Mechanisms Under Reservoir Conditions
Dec 15, 2018 Proppant crushing, a major proppant failure mechanism, occurs in geothermal energy and oil/gas 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 ...
