Reservoir characterization workflows including petrophysical, geomechanical properties and a discrete natural fracture network (DFN) were fundamental steps to build the calibrated, multi-layer earth...

... completion designs. The resultant complex fracture network is converted into unstructured gridblocks for reservoir-performance simulation. Finally, economic analysis is incorporated to evaluate the net present value (NPV) and internal rate of return (IRR) to identify the optimal completion design. Numerical...

... at the injected water during the hydraulic fracturing, how it invades the formation, how it interacts with in-situ fluids, and how it flows (or doesn't flow) back. In this study, we develop a fully coupled geomechanics and fluid flow simulator based on a new discrete fracture network (DFN) methodology...

... with complex fracture networks, and the performance of horizontal wells in tapping heat energy from fractures is investigated. A general Green s function solution for fluid and heat flow in rock matrix is used, as such the need to discretize the matrix domain is eliminated. The model is first used...

.... There are also several highly structured areas in the Montney that increase induced seismicity risk and affect hydraulic fracturing performance. A connection between an active treatment stage and critically stressed fault is required for induced seismicity causation and a meso-scale fracture network is one...

... and Carboniferous sandstone at Telpyn Point, UK. In order to evaluate clustering anisotropy, we employed lacunarity, a parameter that has been previously used to assess scale-dependent clustering in fracture networks. Standard lacunarity vs. scale curves were averaged for scanlines translated along x- and y...

... length. Next, fracture cutoff analysis is applied to generate various hydraulic fracture schemes. Different hydraulic fracture cases are investigated with and without natural fractures to compare the impact of complex fracture networks. Last, various scenarios are numerically modeled by EDFM...

.... Abstract Enhanced Geothermal Systems (EGS) have gained great attention since they promise to delivers geographically disperse, carbon-free energy with minimal environmental impact. Natural fracture networks have a major impact on EGS heat extraction. The objective of our model is to evaluate the impact...

The reservoir simulation is dual porosity, as appropriate for a formation known to be highly fractured, and made more necessary by the complex fracture network induced by hydraulic fracture stimulation. The reservoir simulator uses pseudo-geomechanical features to couple pore pressure...
