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...

... Abstract Understanding of the effective fracture path bounded by a producer and an injector in complex fracture networks plays a key role in the successful geothermal heat extraction from enhanced geothermal systems (EGS). Therefore, there is a need to investigate the impact of well placement...

.... 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...

... of fracture networks comprised of both preexisting natural fractures and newly created fractures from hydraulic stimulation has significant implications for both optimizing production and minimizing the infrastructure footprint on the ecosystem. Towards this goal, this study synthesizes all available datasets...

... 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...

... Abstract The extent and size of the fracture network connected to the wellbore are among the most uncertain parameters for multi-fractured horizontal wells. The uncertainty has a profound impact on production under primary depletion and has even a bigger impact on the recovery during huff-n...

Considering scenarios of multiple wells and pads with different sequences of completions and production, the workflow consists of three key phases. First, complex hydraulic fractures with a discrete naturally fractured network is modeled...
