Research Interests

Enhanced oil recovery processes including polymer flooding, carbon dioxide miscible flooding and thermal recovery. Improved oil recovery processes ranging from waterflooding to application of gelled polymers to control water movement in petroleum reservoirs. Sequestration of Carbon Dioxide in oil and gas reservoirs. Management of petroleum reservoirs and simulation of oil production using reservoir simulators. Transport processes in porous media.

The Carbon Dioxide Initiative in Central and Southwest Kansas

A program to evaluate the potential of applying carbon dioxide miscible flooding to Arbuckle and Lansing Kansas City reservoirs in Central Kansas as well as Morrow reservoirs in Southwest Kansas. The program is an interdisciplinary project involving reservoir characterization, evaluation of minimum miscibility pressures for typical crude oils; simulation of carbon dioxide flooding and economic evaluation of expected results. A major pilot test of carbon dioxide miscible flooding was funded by the U.S. Department of Energy for the period 2000-2010. Carbon dioxide injection began in December 2003 and ended in June 2005 when water injection was initiated. The design and management of this project is facilitated by development of reservoir models to simulate the carbon dioxide and water displacement process.

Permeability Modification using In-Situ Gelation of Polymers

This project involves the study of polymer gels, which can be formed in porous media by the crosslinking of a high molecular weight polymer with a metal ion. The permeability of these gels is low and they are capable of reducing the flow of water substantially through the regions contacted by the gel. Projects range from the study of kinetics of gelation to the dehydration of gels after placement when exposed to pressure gradients from water or oil. One goal of the program is to improve methods of increasing the volumetric sweep of waterfloods by selective placement of gelled polymer systems that reduce the flow of water through high permeability regions. A second goal is to reduce the water flow in production wells that are producing at high water cut.

Management of Petroleum Reservoirs

Prolonging the life of existing petroleum reservoirs is a major goal of this program. Reservoir characterization is combined with modern reservoir simulation to evaluate the performance of natural or induced waterfloods in petroleum reservoirs. Potential operating strategies ranging from rearrangement of waterflood patterns to drilling of new wells are investigated using reservoir simulation. Reservoir heterogeneity is a key parameter in simulations. New methods of incorporating the effects of reservoir heterogeneity are investigated.
