...Mathematical Model We develop a semi-analytical, multiphase RTA model for FR3, as FR3 predominates throughout most of the flowback period and behaves similarly to FR2, except for the additional oil BDF flow regime. The analytical solutions are derived for the linear flow in HF and matrix...

... Abstract Most oil and gas wells are stimulated. In unconventional reservoirs, proppant fracturing is the preferred stimulation technique. However, in higher permeability conventional carbonate reservoirs, matrix acidizing and acid fracturing can also result in stimulated wells, usually...

... exponentially as the number of fracture elements increases. This occurs primarily because the method involves the multiplication of a large dense matrix with a vector. In this study, a fast adaptive integral method (AIM) is used to reduce the computational time significantly when solving for the displacement...

... a novel type-curve method and an iterative workflow. The type curve incorporates the fracture damage effect, which is characterized by choked-fracture skin factor, into the two-phase flow in HF and matrix domains. The type-curve method can be applied to inversely estimate choked-fracture skin factor...

Wormholes can effectively connect the well with the reservoir. However, if the carbonate reservoir is naturally fractured, it will be difficult...

... There have been, in recent years, quite a few approaches developed and investigated for coupled flow and poroelasticity in fractured porous media. One approach is based on dual porosity models (DPM) which implicitly treats the fracture as interacting continuum with rock matrix. In this approach...
