Development of a Moving Grid Point Method for the Solution of Multicomponent, Multiphase Flow Problems in One Dimension
The theory for a single component moving point finite difference method is extended for multicomponent, multi phase porous media flow problems in one dimension. The modified technique is applied for the solution of a three ...
A Study of Polymer/Surfactant Interactions for Micellar/Polymer Flooding Applications
Static measurements of the phase volumes of mixtures of surfactant, polymer, alcohol, water, n-octane, sodium chloride, and in some cases polymer additives were made. A limited number of viscosity, phase concentration, and ...
The Rheology of Viscoelastic Fluids for Oil Recovery: A Study of Micellar/Polymer Flow Over a Wide Range of Shear Rates in Porous Media
The rheological behavior of selected polymer solutions used for mobility control in waterflooding, micellar fluids used in low-tension chemical flooding, and micellar/polymer mixtures has been examined. Poly-mers used were ...
Reservoir Characterization of North Buck Draw Field Based on Tracer Response and Production/Injection Analysis
A major goal in reservoir characterization is to develop methods to describe the spatial distribution of properties that incorporate observed heterogeneity and variability due to the geologic complexities. Among these, ...
Numerical Simulation of Interwell Heterogeneity in Carbonate Reservoirs Based on an Outcrop Study
Low recovery efficiency in the carbonate resevoirs of West Texas are observed that range from 15 to 45%. The restricted platform type of depositional system contains a major portion of the unrecovered mobile oil in the ...
A Simple Gravity Override Predictive Model of Steamdrive
A predictive model for steamflooding, based on a predominantly steam override scenario, was developed and tested with twenty-three field cases reported in the literature. Acceptable matches were readily obtained with ...
Liquid Crystals for Mobility Control
Determination of Field Scale Dispersivities by Mathematical Modeling
Dispersion in heterogeneous porous media results from the simultaneous action of a mechanical phenomenon and molecular diffusion. The mechanical contribution ari-ses from discrepancies in flow streamlines caused by ...
Analytical Solutions for Hydraulic Fracture Diagnosis
This work presents old and new analytical solutions for hydraulic fracture diagnosis. The main body of this work is divided in two parts: Part I presents the main developments, theories and applications of pressure transient ...
