... to optimize well spacing, landing and completion design in a multi-bench pad development in the DJ basin. Reservoir characterization workflows including petrophysical, geomechanical properties and a discrete natural fracture network (DFN) were fundamental steps to build the calibrated, multi-layer earth...

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...

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...

.... 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...
