Evolution of Proppant Embedment and its Impact on Shale Permeability

58th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: Hydraulic fracturing is important for modern gas extraction. However, the proppant embedment affects gas recovery significantly. This study investigates the impact of proppant embedment on permeability over time in shale reservoirs.

Evaluation of geothermal development considering proppant embedment in hydraulic fractures

Renewable Energy, 2020
Abstract 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.

Decomposition of Rock Deformation During Proppant Embedment

58th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: 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 ...

Reservoir Depletion-Induced Proppant Embedment and Dynamic Fracture Closure

SPE Middle East Oil and Gas Show and Conference, 2019
Abstract 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.

A Model to Calculate Fracture Conductivity Considering Proppant Transport and Embedment Depth

Chemistry and Technology of Fuels and Oils, 2021
The 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 ...

The effect of proppant embedment upon the long-term conductivity of fractures

Journal of Petroleum Science and Engineering, 2007
Experimental 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.

Modelling of Micro-Sized Graded Proppant Injection in the Natural Fractures Around a Hydraulic Fracture with Consideration of Proppant embedment and Deformation

Abu Dhabi International Petroleum Exhibition & Conference, 2020
Abstract Natural fractures are usually developed in unconventional reservoirs like shale, tight sandstone, CBM etc. Volume fracturing has been extensively used in such reservoirs to create a complex fracture network to provide flow paths for oil and gas.

Improved discrete element modeling for proppant embedment into rock surfaces

Acta Geotechnica, 2019
Brinell indentation tests were performed on Montney siltstone, and the results were compared with discrete element indentation simulations that use the micro-parameters calibrated using compression test data from the same siltstone samples. The simulated proppant indentation into the rock surface can be 15% less than the laboratory measurements.

Computation model of proppant embedment depth based on dimensional analysis

Journal of Coal Science and Engineering (China), 2013
Hydraulic fracturing is designed to form a high-conductivity fracture. The proppant will embed into the formation rock, especially in soft rock, owing to the interaction between proppant and fracture surface after fracture closure. Proppant embedment would reduce the fracture width and then lower the fracture conductivity.
