A Robust Model for Integration of Sand-Arch Stability and Fractal Wormhole Network in CHOPS and post-CHOPS Process Simulation
DownloadSpring 2024
Cold heavy-oil production with sand (CHOPS) is a primary recovery process in unconsolidated heavy-oil reservoirs. The recovery factor typically ranges from 5% to 15% of the initial oil in place (OOIP). Approximately 90% of crude oil is left underground with considerable exploitation potential...

Fall 2019
Thermal cracking of heavy oils is important industrially in processes such as visbreaking, coking and residue hydroconversion. In these processes, residue conversion is limited by formation of heavy products. Heavy product formation also contributes to industrially relevant problems such as...

Integration of microseismic and time-lapse seismic data with application to a heavy oil reservoir
DownloadFall 2021
Thermal heavy oil extraction techniques are high temperature and pressure procedures to produce heavy oil. Elevated temperature and pressures alter the subsurface stresses, causing shear failure of rock within and surrounding the steam front. The steam also introduces volumetric changes at the...

Liquid Crystal Domain Formation and Structure in Humic Substances + Water + Hydrocarbon Mixtures
DownloadFall 2020
The liquid crystal phase state has long-range order in one or two dimensions and is an intermediate phase state between the unordered liquid state and the solid crystalline state with long-range order in three dimensions. Liquid crystals, comprising spherical liquid crystalline shells surrounding...

Multi-Objective Optimization of the Steam Alternating Solvent (SAS) Process using Pareto-based Multi-Objective Evolutionary Algorithms
DownloadSpring 2022
The Steam Alternating Solvent (SAS) process is a relatively new auspicious alternative recovery process to produce heavy oil and bitumen resources. This process consists of injecting steam and solvent (i.e. propane) alternatively using the same well configuration as the widely adopted...
