Graduate Courses

PETE 605: Phase Behavior of Hydrocarbon Fluids. (Credit 3) Significantly revised this course by adding topics such as: gas hydrates, paraffin deposition, water/hydrocarbon phase equilibria. Heavy emphasis on use of Equations of State for phase equilibria computations and rigorous thermodynamic approaches. Elimination of repetitive material from undergraduate courses.

PETE 616: Engineering Near Critical Reservoirs. (Credit 3). Redesigned this course from scratch. Incorporated workshops using commercial simulators. Stressed the use of UNIX and Eclipse 300 simulators. The course ends with a comprehensive competition project to develop a gas condensate field using the strategies learned in the course.

PETE 607: Chemical and Miscible EOR. (Credit 3) Completely redeveloped this course by incorporating more fundamentals. Topics included include rheological behavior of polymers used in EOR, phase equilibria interactions in CO2 flooding, environmental and economic issues.

PETE 609: Enhanced Oil Recovery Processes. (Credit 3) Completely developed this course by incorporating more fundamentals. Topics included include rheological behavior of polymers used in EOR, phase equilibria interactions in CO2 flooding, environmental and economic issues. Modern technologies in thermal flooding applications including : SAGD, insitu combustion and use of additives to increment heavy oil recovery and in-situ upgrading.

PETE 685: Problems in Phase Behavior. (Credit 3-4) Design of a series of problems that require extensive use of simulations. These include evaluation of current fluid property correlations for viscosity, density, MMP (minimum miscibility pressure) with data bases. Characterization procedures for the C7

+ fraction. Development of codes to evaluate constant volume depletion of gas condensates. Sensitivity analysis using Equations of State with various mixing rules. Stability analysis techniques.

Chemical Enhanced Oil Recovery: Evaluation of pore size distributions and relative permeability curves before after polymer treatment from capillary pressure data. Sensitivity analysis on oil recovery vs. oil/polymer/rock properties. Analytical Methods to Estimate CO2 Storage in Depleted Oil and gas Reservoirs Thermodynamic models to estimate the ultimate CO2 storage capacity of a reservoir, this particular project led to 4 recent publications

PETE 644: CO2 Capture and Uses: Sequestration, Enhanced Oil Recovery (EOR) (Credit 3) CO2

capture and storage (CCS) involves the injection and containment of CO2

in geological

structures such as depleted oil and gas reservoirs, onshore and offshore saline aquifers located deep in the earth’s crust, salt caverns or un-minable coalbeds. This is an approach that can be used to improve the energy production from existing fossil fuel operations (Enhanced Oil and Gas Recovery) as well as a means of reducing greenhouse gas emissions. This course will provide a scientific and technological foundation designed to provide answers to questions important to those interested in investigating the potential of CCS to enhance energy production and reduce greenhouse gases as well as to policy makers.
