dc.description.abstractWith thousands of multi-fractured horizontal wells completed in the Pembina Cardium field, adapting and utilizing existing wells and infrastructure for future CO2-EOR development is economically and environmentally attractive. Even so, drilling, completion and hydraulic fracturing design and practices can vary greatly across the field. In this thesis, an effective workflow is developed to evaluate the success of different strategies for completing Cardium horizontal wells and their suitability for conducting CO2 injections for EOR. In addition, a method for identifying re-fracturing horizontal well candidates is developed. WAG injection is a commonly employed technique to improve sweep efficiency in gas flooding processes. A study of different WAG injection schemes is also conducted and compared to continuous CO2 injection in this work, which includes constant WAG, SWAG, and hybrid/tapered WAG injection. The effects of various WAG parameters are investigated. The results indicate that an appropriately designed injection scheme can improve oil recovery substantially.en_US
