Modeling of In Situ Combustion for Enhanced Oil Recovery in a Carbonate Reservior Bahman Moazzeni pour Bahman mo@gmail com Date of Submission 2012 04 30 Department of Chemical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Mohammad Reza Ehsani mr ehsani@cc iut ac irAbstractOne of the methods for enhanced oil recovery from heavy oil resources is in situ combustion Ascomplicated as this process is it also has higher efficiency compared to other processes of heavy oilrecovery and can be used in a wide range of resources On the other hand because this trend can be used indeep resources it is appropriate for the resources in Iran Therefore research and review regarding thisprocess have been significantly increased within the recent years due to international need for oil One 3Dmodel in three phases of oil water and gas has been considered for modeling in situ combustion process For the components which are distributed in two or more phases phase equilibrium has been consideredamong the phases In this model the energy conservation equation total and partial mass balance equationshave been written for all components including oxygen non condensable gas light oil hydrocarbon heavyoil hydrocarbon water and coke Additionally the auxiliary equations are presented for calculations ofpermeability changes capillary pressures reservoir porosity PVT properties of fluids viscosity enthalpyand etc Finally constraint equations including mole fractions in two phases of oil and gas and alsosaturation percentage of phases are added to the equations After writing the equations and theirdiscreteness the finite difference procedure has been used for solving the equation by applying theboundary and initial conditions The related program has been written in the Matlab Software In the nextstage accuracy of the present model has been reviewed comparing with experimental data and result of theother models After assuring the accuracy of the model the present model was used in one of the heavy oilreservoir for reviewing the in situ combustion process and the results were gathered in the conclusionsection The reservoir simulation results in 1D mode shows that almost 90 of the reservoir in situ oil hasbeen recovered after 150 days of simulation from which 30 is related to production of light oil due tocracking reaction At the same time in such condition recovery rate of water is over 100 which is due towater production as the result of oxidation reactions These results show that in 3D modeling of thereservoir location of the injection well is seriously effective on parameters like oil and water saturation andthe blocks close to the injection well show faster reactions toward air injection The process simulation insuch condition shows that after 150 days after initiation of the simulation by passing the combustion frontthrough the reservoir blocks the temperature in theses blocks will be maximized which is 870 Fahrenheit isthe maximum Keywords In situ combustion Heavy oil Enhanced oil recovery Modeling Reservoir
