... 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 results show that with the same...

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...
