Item Open AccessThe Study of Vapour Extraction (VAPEX) on Heavy Oil Reservoirs and Upscaling Approaches(Faculty of Applied Science and Engineering, University of Regina, 2011-04-02) Jamshidi, Tayebeh; Movahedzadeh, ZeinabVAPEX reduces the viscosity of heavy oil by injecting it with a light hydrocarbon solvent. The resulting diffusion and mass transfer are strongly dependent on the injection rate, solvent concentration, cementation factor, and other reservoir parameters. The aim of this project is to modify the relationships between these parameters using laboratory test results and actual field data in order to improve the accuracy of the predictive mathematical models, since results obtained from laboratory data deviate considerably from real field behaviour. Item Open AccessCO2 Injection in the Bakken Formation(Faculty of Applied Science and Engineering, University of Regina, 2011-04-02) Stoeck, Alyssa; Johnson, JulienThe Bakken play has been of great interest to oil companies in recent years. It produces high quality oil from a reservoir with low porosity and low permeability, but has a rapid decline rate immediately after production starts. This project examines and analyzes the effectiveness of CO2 injection into the formation via horizontal wells to increase and maintain production in an economic manner. Item Open AccessOptimization of a Heavy Crude Oil Heater Treater(Faculty of Applied Science and Engineering, University of Regina, 2011-04-02) Hassan, Nasir; Wild, EvanCanadian Natural Resources Limited (CNRL) owns and operates a heavy crude oil treating facility near Elk Point, AB. This facility currently uses four horizontal heater treaters to effectively reduce the basic sediment and water content of the produced crude oil. In recent years, there has been a decline in the overall performance of the heater treaters. The goal of this project is to optimize the heater treaters and improve their operating efficiencies by determining both the optimum treating sizes and operating temperatures of the vessels.

This project discusses the design and analysis of slug tests in a variety of field conditions. Item Open AccessOptimizing Drill Bit Selection using Artificial Neural Networks(Fa, 2011-04-02) Lertnimoolchai, Yanee; Ogunrinde, KanyinThe proper bit can increase the rate of penetration (ROP) and reduce overall drilling costs. Conventional analytical optimization methods alone are not sufficient due to the complexity and non linearity of the factors affecting ROP. Artificial Neural Networks (ANNs), capable of handling complex relationships, are used to predict bit performance. A model created using ANNs allows for the selection of the optimal bit for any given pre-specified set of data.
