Hydraulic fracture propagation in naturally fractured reservoirs: Complex fracture or fracture networks [PDF]
Journal of Natural Gas Science and Engineering, 2019 All reservoirs are fractured to some degree. Depending on the density, dimension, orientation and the cementation of natural fractures and the location where the hydraulic fracturing is executed, pre-existing natural fractures can impact hydraulic ...

On the influence of fluid rheology on hydraulic fracture
, 2021 We analyse a problem of a hydraulic fracture driven by a non-Newtonian shear-thinning fluid. Fluid viscosity is described by the four-parameter truncated power-law model.
