Light Weight Composite Proppants: Computational and Experimental Study

abstract

• In this article, the computational and experimental techniques developed to understand and characterize the mechanical response of polymer coated walnut shell proppants is reported. Microscopy and single particle compression are employed to study cellular microstructure, elucidate influence of particle shape, and study cellular constitutive behavior. Computational models are created to simulate single-coated and uncoated particles under compression. The results reveal significance of the particle shape and constitutive material properties on its mechanical response. Polymer coating provides a marginal improvement in load transfer while stress and strain fields show a more gradual transition. 2012 Copyright Taylor and Francis Group, LLC.
