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.

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 influence of proppant breakage, embedding, and particle migration on fracture conductivity
Journal of Petroleum Science and Engineering, 2020Abstract Many studies that aim to reduce the damage to fracture conductivity caused by proppant breakage and embedding have been conducted. Few studies, however, have addressed the damage to conductivity caused by proppant particle migration, which is often neglected in practical design.

A Model to Calculate Fracture Conductivity Considering Proppant Transport and Embedment Depth
Chemistry and Technology of Fuels and Oils, 2021The accuracy of predicting fracture conductivity is very important in hydraulic fracturing. However, most models pay more attention to the solution of fracture conductivity value, without considering the distribution of the fracture conductivity. It is also important to couple the proppant embedment depth and fracture conductivity, especially for the ...

Decomposition of Rock Deformation During Proppant Embedment
58th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: The deep-formation rock has various deformation modes such as viscosity, elasticity and plasticity under the action of complex geo-stress, high temperature and high pore pressure. These deformation modes increase the proppant embedment depth at different stages and affect the long-term conductivity of the ...
