Mechanism of Single Proppant Pressure Embedded in Coal Seam Fracture

Energy & Fuels, 2021
The strength and rigidity of proppant and coal are quite different. Proppant is easily embedded in coal, resulting in the decrease of fracture aperture and conductivity. The mechanism of proppant embedded in the coal fracture surface needs further study.

Thermal–Mechanical Modeling of a Rock/Proppant System to Investigate the Role of Shale Creep on Proppant Embedment and Fracture Conductivity

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, 2012
Abstract 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, 2013
Abstract 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.

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.

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 ...

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.

The influence of proppant breakage, embedding, and particle migration on fracture conductivity

Journal of Petroleum Science and Engineering, 2020
Abstract 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.
