“…To perform hydraulic fracturing design, FracMan has also incorporated other features including proppant transport, synthetic microseismic events, etc. With these features, FracMan has been extensively used to carry out hydraulic fracturing design in the natural gas, deep geothermal and deep mining industries [71,73,101,351].…”

Along with horizontal drilling techniques, multi-stage hydraulic fracturing has improved shale gas production significantly in past decades. In order to understand the mechanism of hydraulic fracturing and improve treatment designs, it is critical to conduct modelling to predict stimulated fractures. In this paper, related physical processes in hydraulic fracturing are firstly discussed and their effects on hydraulic fracturing processes are analysed. Then historical and state of the art numerical models for hydraulic fracturing are reviewed, to highlight the pros and cons of different numerical methods. Next, commercially available software for hydraulic fracturing design are discussed and key features are summarised. Finally, we draw conclusions from the previous discussions in relation to physics, method and applications and provide recommendations for further research.

“…Hydraulic fracturing using a horizontal well is an essential production technique in shale gas formations [1][2][3][4][5]. Various approaches have been developed to model hydraulic fracturing phenomena to obtain an accurate estimation of shale gas production-for example, extended and generalized finite elements methods (XFEM and GFEM, respectively) [6][7][8][9], displacement discontinuity methods (DDM) [10][11][12], boundary element methods (BEM) [13][14][15], phase-field formulations [16][17][18][19][20][21][22], and discrete fracture network (DFN) [23][24][25].…”

This study proposes a hydraulic fracture propagation model with a mixed mode comprising opening and sliding modes to describe a complex fracture network in a naturally fractured shale gas formation. We combine the fracture propagation model with the mixed mode and the uniaxial strain model with tectonic impacts to calculate the stress distribution using geomechanical properties. A discrete fracture network is employed to realize the fracture network composed of natural and hydraulic fractures. We compare the fracture propagation behaviours of three cases representing the Barnett, Marcellus, and Eagle Ford shale gas formations. Sensitivity analysis is performed to investigate the effects of the geomechanical properties of the reservoir on the sliding mode’s contribution to the mixed mode. The numerical results highlight the significance of the mixed mode for the accurate assessment of fracture propagation behaviours in shale gas formations with high brittleness.

“…While numerical studies dealing with fracture interaction and reactivation already exist in the literature, they make use of the discrete fracture network (DFN) approach at larger scales (reservoir scale) with several assumptions or simplifications (e.g. [18,60]). Using a representative scale model, we considered realistic fault-related structures in a deterministic way to interpret and fit real experimental data.…”

Hydromechanical reactivation of natural discontinuities: mesoscale experimental observations and DEM modeling

et al. 2019

Fracture interaction mechanisms and reactivation of natural discontinuities under fluid pressurization conditions can represent critical issues in risk assessment of caprock integrity. A field injection test, carried out in a damage fault zone at the decameter scale, i.e., mesoscale, has been studied using a distinct element model. Given the complex structural nature of the damage fault zone hydraulically loaded, the contribution of fracture sets on the bulk permeability has been investigated. It has been shown that their orientation for a given in situ stress field plays a major role. Based on these results, a simpler model with a fluid-driven fracture intersecting a second fracture has been set up to perform a sensitivity analysis. It is in presence of a minimum differential stress value with a minimum angle with the maximum principal stress that the second fracture could be both, hydraulically and mechanically reactivated. Results also showed that in the vicinity of the fluid-driven fracture, a natural fracture will offer contrasted hydromechanical responses on each side of the intersection depending on the stress conditions and its orientation with respect to the stress field. In this case, we show that a hydromechanical decoupling can occur along the same plane. These results provide insights into fracture-controlled permeability of fault zones depending on the properties of the fractures and their hydromechanical interactions for a given in situ stress field.
