Paper Number: SPE-195980-MS
... to history match both models because of non-uniqueness between fracture area and permeability. Sensitivity analysis simulations are performed to assess the impact of well and cluster spacing on net present value. Relative to the high permeability model, the low permeability model has a greater optimal well...

... into accessible pores and inaccessible part of the rock (IRP) and characterize pore compressibility values as a function of pressure. As local pore pressure decreases, formation porosity, pore radius, Knudsen number and thus flow mechanisms are subjected to change with time. Hence, a new permeability model...

Paper Number: SPE-181449-MS
... Abstract Permeability is one of the most important petrophysical parameters in formation evaluation and reservoir description. Unlike porosity and saturation, permeability can be a non-zero rank tensor. Most published log-based permeability models are only used to determine scalar or isotropic...
