A Comparative Study Of Experimental And Computed Compressibility Factors Of Ethane-Carbon Dioxide-Nitrogen System, Brij Raj Misra
A Comparative Study Of Experimental And Computed Compressibility Factors Of Ethane-Carbon Dioxide-Nitrogen System, Brij Raj Misra
Masters Theses
"The purpose of this study was to provide compressibility factor data on the ethane - carbon dioxide - nitrogen system. Compressibility factors were experimentally determined for 5 mixtures at room temperature, 100ºF, 125ºF , 150ºF and pressures ranging between 1000 psig to 4000 psig. An attempt was also made to compare the experimental data with the compressibility factors obtained by the additive volume method. The deviation of the computed compressibility factor from the experimental data was found to be in accordance with the general view of previous workers. However, the deviation was found to be a maximum in the pressure …
A Three-Dimensional Mathematical Simulator Of Multiphase Systems In A Petroleum Reservoir, Leonard Koederitz
A Three-Dimensional Mathematical Simulator Of Multiphase Systems In A Petroleum Reservoir, Leonard Koederitz
Doctoral Dissertations
"A generalized digital analysis for calculating three phase, three dimensional flow in reservoirs is developed. The computerized mathematical model is applicable to depletion drive, gas injection, water injection, and/or aquifer drive systems with modifications specific to the simulation criterion of that type of drive and includes fluid compressibility effects, gravity drainage and capillary pressure. The simulation allows arbitrary consideration of reservoir heterogeneity, geometry, well locations and rates of production. An innovation to the alternating direction technique for linear differential equations discussed by Brian is developed and employed in order to render the method of solution applicable to non-linear differential equations. …
Simulation Of A Gas Storage Reservoir With Leakage By A Two-Dimensional Layered Mathematical Model, Steven William Ohnimus
Simulation Of A Gas Storage Reservoir With Leakage By A Two-Dimensional Layered Mathematical Model, Steven William Ohnimus
Doctoral Dissertations
"A generalized mathematical model was developed for two-dimensional compressible fluid flow accounting for the effects of relative permeability capillary pressure, and gravity drainage in addition to the reservoir properties of rock heterogenity and reservoir geometry. The generalized model developed was applied to an aquifer gas storage reservoir in which vertical leakage occurred from the main reservoir to two adjacent overlaying zones. The experimental results of Thomas, et al. were utilized in applying the model to gas storage injection/withdrawal periods yielding reasonable results for the three layers"--Abstract, page ii.

Numerical Simulation Of Forward Combustion In A Radial System, Tommie C. Wilson
Doctoral Dissertations
"A generalized mathematical model is described for the thermal recovery of oil in a radial system in which there are conductive heat losses to the surrounding formations, three phase fluid flow, conductive-convective heat transfer within the producing formation, combustion, and aqueous-phase changes considered. The mathematical form of the temperature equation requires that numerical solutions be obtained with a digital computer for which the numerical approximations of the partial differential equations are presented and the results discussed. The analysis is applied to field size simulations of a forward combustion project to permit direct field analyses of significant importance for accurate reproductions …

A Comparative Study Of Experimental And Computed Compressibility Factors Of Methane-Nitrogen-Carbon Dioxide System, Piloo Eruchshaw Ilavia
Masters Theses
"Experimentally determined compressibility factors of a natural gas with impurities like carbon dioxide and nitrogen are found to differ with the values computed by various methods making use of compositional breakup of the gas. Compressibility factors for five mixtures of known composition were experimentally determined at room temperature, 100ºF, 125ºF, and 150ºF, and at pressure ranging between 1000 psi to 4000 psi. Using the known composition of the mixtures, compressibility factors were calculated by additive volume method and by Eilerts method. The deviation between computed and experimentally determined compressibility factors are at a maximum in the lower and higher pressure …

Chromatographic Determination Of Hydrocarbons Based On Retention Time Data For Squalene And Tetracyanoethylated Pentaerythritol Columns, Mehdi Honarpour
Masters Theses
"The purpose of this thesis is to investigate the theory that when several members of a homologous series are injected into a gas chromatograph, at a given flow rate and column temperature, the lograrithm of their retention time as a function of some increasing property of the homologous series may be presented as a straight line and to develop their equations. Experimental procedure was accomplished for the normal paraffin series with 7 1/2% squalene and 10% Tetracyanoethylated Pentaerythritol (T.C.E.pageE.) columns and the relation between retention time and carbon number was determined. The same type of development was employed for aromatic …
A Permeability Scaling Technique In The Numerical Simulation Of Water Coning, Virendra Kumar Dutta
A Permeability Scaling Technique In The Numerical Simulation Of Water Coning, Virendra Kumar Dutta
Masters Theses
"A two-dimensional, two-phase, radial, horizontally layered water coning simulator was programmed for large memory digital computers. A permeability sealing technique is developed which allows the use of large size blocks as production blocks. As a result of this technique large time steps have been used without causing saturation instabilities around the well bore and the permeability scaling technique allows a more realistic simulation of a water cone. The IMPES method is used to calculate pressure and saturation in the system for each finite time step. The behaviour of the simulator is studied for various factors affecting the advance of a …
Comparison Of The Buckley-Leverett Technique With A Numerical Simulation Model Containing Heterogeneity And Capillary Pressure, Krishna Kumar Singh
Comparison Of The Buckley-Leverett Technique With A Numerical Simulation Model Containing Heterogeneity And Capillary Pressure, Krishna Kumar Singh
Masters Theses
"A numerical model for a linear, two-phase fluid flow system has been developed with the capabilities of accounting for heterogeneity and capillarity. The model developed is general enough to analyze either water-oil or gas-oil systems. A hypothetical petroleum reservoir (containing only water and oil) under water flood was studied. The results for the homogeneous, no capillary pressure case were found to be similar to those obtained by the Buckley-Leverett technique. The study shows that the Buckley-Leverett is accurate even for a certain degree of heterogeneity. Also, capillarity does not substantially alter the results for the system studied. The results obtained …
Determination Of Reservoir Characteristics From Capillary Pressure Curves And Electrical Properties Of Rocks, Prasanta Kumar Guharoy
Determination Of Reservoir Characteristics From Capillary Pressure Curves And Electrical Properties Of Rocks, Prasanta Kumar Guharoy
Masters Theses
"Based upon the assumptions that a porous medium is analogous to a bundle of capillary tubes and that there is equivalence of electrical and hydraulic tortuosity in a porous medium, empirical expressions are presented which relate capillary pressure data and electrical properties of the rock to the porosity, permeability and relative-water permeability, respectively, of completely water-wet rocks. Experimental data are presented for comparison in order to verify their validity. Three principal models are presented, each of which is characterized by a particular expression for estimating tortuosity. The method of determining this parameter was varied in order to find the form …
