... of hydromechanical couplings on fracture propagation over different time horizons. INTRODUCTION Generally, fluid fracturing is the process by which a fracture is generated and propagates as a result of fluid loading (i.e., pressure) applied by a fluid inside the fracture. Fluid fracturing modeling requires...

... on the better understanding of micro-mechanisms leading to formation of fracture process zone (FPZ) and the following fracture propagation. The interpretation was based on the stress-induced changes in locations and source mechanisms of AEs. As a result, the micro-cracking can be divided into three following...

...-peak cyclic loading (PPCL). The lateral strain-controlled and double-criteria damage-controlled testing methodologies were implemented for the experiment. A combined post-peak Class I-II behavior to different extents was detected for soft to strong rocks, while the unstable fracture propagation...

... ABSTRACT: In this paper, a coupled thermal-hydraulic-mechanical modeling was proposed based on the linear elastic fracture mechanics to understand the effect of thermal stress field on fracture propagation. Due to a cooling zone was formed in the matrix when the fracturing fluid injection...

... Abstract In this paper, we present a fully 3D multiple hydraulic fracture propagation from horizontal wells considering proppant transport modeling. The numerical model considers coupling between the fluid pressure and reservoir stresses and allows for dynamic modeling of 3D fracture...

... Abstract In this study, a two-dimensional fully coupled model based on the extended finite element method (XFEM) is established. The model incorporates rock deformation, fracturing fluid flow, fracturing fluid leak-off and mixed mode fracture propagations. The model has been validated against...

Several mechanisms may coexist to explain initiation and progressive failure due to temperature variation: thermal...

... propagation), whereas rock elastic properties in the CDM equivalent damage zone evolve smoothly with the displacement imposed at the boundary of the domain. In the CZM and XFEM, fracture propagation stabilizes after a turning point: this point coincides with damage initiation in the DSID model. As a result...

... Abstract Increase in permeability of rock mass is vital for both petroleum and geothermal applications. Hydraulic fracturing is a common method to create and increase the permeability for production. Due to the complexity of fracture propagation in a naturally fractured medium, understanding...

... Abstract Hydraulic fracture is a frequently used technique in the Oil and Gas industry to create high permeability pathways for extraction of hydrocarbons. Numerical simulation of this method poses challenges such as representation of 3D fractures, propagation of randomly oriented fractures...
