Gas coning is a tendency of the gas to impel the oil downward in an inverse cone contour toward the well perforations. Once the gas reaches the well, gas production will dominate the well flow and the oil production will hence significantly decrease. From an economical and operational standpoint this condition is undesirable since the gas price is much lower than the oil price, and the gas hand...

Two reservoirs domiciled in a well have been analysed this study order to obtain the quantitative reservoir properties. These properties are essential not only for development and optimization but also accurate decision-making prior exploitation production. A suite of composite logs comprising caliper log, gamma-ray (GR) density resistivity sonic transit time obtained from field onshore Niger D...

Abstract A significant behavior of carbonate reservoirs is poor correlation between porosity and permeability. With the same porosity, permeability can vary by three orders magnitude or more. An accurate estimation for reservoir has been a challenge many years. The aim this study was to establish relationships pore throat, This indicates that throat radius corresponding mercury saturation 20% (...

This study is focused on a solution for the problem of suspension penetration in porous formation. Such forms basis injection profile diversion technology oil reservoir sweep improvement. A conventional model deep-bed flow was used to describe process. The slug followed by water injection, and inflow before after treatment investigated. For first time, criteria that determine effectiveness impr...

Advanced drilling technology makes it possible to penetrate oil and gas sites with deep bedding of reservoir, a complex multi-layer structure high reservoir temperature at the well bottom, reaching 150°C. The difficult geology strata leads fact that productive layers are flooded unevenly. In this work causes for water cut in reservoirs given, repair insulation technologies isolation water-beari...

A continuum damage mechanics (CDM) based constitutive model has been developed to describe elastic, plastic and damage behavior of porous rocks. The pressure sensitive inelastic deformation of porous rocks together with their damage mechanisms are studied for drained and undrained conditions. Fracture mechanics of microcrack andmicro-void nucleation and their coalescence are incorporated into t...

The accurate simulation of coupling between flow and stress in saturated porous media is a major issue in a broad variety of fields, ranging from reservoir engineering to biomechanics. Despite the intensive research carried out in recent years, the numerical solution to the partial differential equations governing the behaviour of real fluid saturated heterogeneous porous media still represents...

We consider numerical solutions of the Darcy and Buckley-Leverett equations for ow in porous media. These solutions depend on the geology of the porous media, which is given here as a realization of a random eld to describe the reservoir permeability. We measure the solution error as the diierence between the oil production rates (oil cut) for ne grid and upscaled coarse grid solutions of the e...

We present a new conceptual approach for modeling of fluid flows in random porous media based on explicit exploration of the treelike geometry of complex capillary networks. Such patterns can be represented mathematically as ultrametric spaces and the dynamics of fluids by ultrametric diffusion. The images of p-adic fields, extracted from the real multiscale rock samples and from some reference...
