Rock Mechanics and Rock Engineering, 2021
Under high temperature and stress reservoir conditions, proppant embedment induced by the time-dependent creep behavior of shale rocks has posed great challenges to the long-term maintenance of fracture conductivity in unconventional reservoirs. In this study, a numerical workflow combining a 3D continuum–discrete mechanical coupling approach with the ...

Modeling of Proppant Embedment: Elastic Deformation and Creep Deformation
SPE International Production and Operations Conference & Exhibition, 2012Abstract Unconventional reservoir has become the hotspot of development in petroleum industry. In shale reservoir, some fracture is only propped by a monolayer 100mesh proppant. Fracture width is very small and under the condition of low rock hardness and high effective closure stress, the fracture will heal after a period of time ...

New Mathematical Models for Calculating the Proppant Embedment and Conductivity
International Petroleum Technology Conference, 2013Abstract Proppant embedment plays a significant role in decreasing fracture aperture and conductivity, especially for weakly consolidated sandstones, shale (oil and gas) rock, and coal beds. Empirical and semi-empirical models were usually used to calculate the embedment of proppants.

Evaluation of geothermal development considering proppant embedment in hydraulic fractures
Renewable Energy, 2020Abstract Conductivity in hydraulic fractures embedded with proppants has a great impact on the efficiency of geothermal development in an enhanced geothermal system. This study explores the effects of proppants and hydraulic fracture arrangement on the efficiency of geothermal development by developing a thermo-hydro-mechanical coupled model.

Numerical study of proppant embedment under proppant-coal seam interaction
Powder TechnologyExperimental studies on proppant embedment in coal seams often overlook factors like pulverized coal shedding, leading to inaccuracies. This study developed a numerical model for proppant embedment in coal seams using elastoplastic theory and the material point method (MPM).

Reservoir Depletion-Induced Proppant Embedment and Dynamic Fracture Closure
SPE Middle East Oil and Gas Show and Conference, 2019Abstract An optimized stimulation design not only achieves high productivity during early times, but also necessitates maintaining conductive flow paths during the life of a well. Because of proppant settling and bridging, proppants are not uniformly distributed within developed fracture networks.

The effect of proppant embedment upon the long-term conductivity of fractures
Journal of Petroleum Science and Engineering, 2007Experimental research on proppant embedment in formation core has been done for the first time in China using FCES-100 (Long-Term Fracture Conductivity Evaluation System). In the experiments, the degree of embedment to different cores and the damage to conductivity were studied in the condition of different concentrations and types of proppants.
