The viscosity, as a function of density and temperature, of long chain normal alkanes ( n -alkanes) in the liquid phase, is modelled using the Free Volume model, as presented by Allal, Moha-Ouchane and Boned in 2001. Free Volume molecular characteris

Large errors in oil viscosity predictions result in large production rate errors during numerical simulation, due to a first-order dependency of flow rates on viscosity. Questions that arise during thermal simulation studies of heavy oil are (1) whic

Summary This paper describes a multistep pseudofunction-generation process designed to incorporate several scales of heterogeneities into one set of final pseudofunctions to be used in large gridblocks for field simulations. A detailed description of

The presence of vugs in a naturally fractured reservoir can be a significant source of reserves. These vugs can be connected to the fracture system or be isolated in matrix material which constitutes a triple porosity system. The modeling of the disp

Engineers using numerical reservoir simulators to model fractured reservoirs typically have used straight-line (corner-to-corner) relative permeabilities and zero capillary pressure in the fractures, without a clear understanding of how these two par

Summary This paper describes an attempt to determine the relationship between a geological layer's height and width from published data on outcrops. Data from 11 outcrops are included in the study. A statistical analysis is performed on the highly va

Summary The effect of small- and intermediate-scale heterogeneities on miscible displacements is investigated by Monte Carlo simulations in a two-dimensional (2D) flow field containing random permeabilities and random layering. The effect of the vari

The two-dimensional steady flow of an incompressible viscous fluid past a circular cylinder, placed symmetrically in a simple shear field, has been studied for both the stationary and the freely rotating case by solving numerically the Navier-Stokes

Abstract A multi-component, three-dimensional model was developed to simulate the fluid flow phenomena occurring during the in situ uranium leaching process and subsequent aquifer renovation. This fluid flow model uses knowledge of the total dissolve
