TL;DR: In this article, the authors investigated the effect of proppant addition schedule on the propper distribution in a straight fracture for slickwater treatment, and designed a series of case studies to investigate the impacts of injection velocity, injection proppers concentration, multi-concentration proppers addition order and multi-size propper addition order on proppers distribution.

TL;DR: In this article, a 3D displacement discontinuity method (3D DDM) is introduced to model multiple fractures in a stage in 3D. The fracture geometry is prescribed, which combined with vertical and horizontal fractures.

TL;DR: In this paper, a three-dimensional fracture model was developed to simulate the interactions between vertical/slanted hydraulic fractures and frictional discontinuities (such as natural fractures or horizontal/oblique bedding plane segments) with non-orthogonal approach angle.

TL;DR: In this article, an unsteady-state heat transfer model for closed loop geothermal system (CLGS) is presented that considers variation of convection heat transfer coefficient and finite difference method is employed to solve the mathematical model.
