Physics-based large-scale reservoir models are routinely employed in the prediction of the SAGD (Steam Assisted Gravity Drainage) process under different operation situations. However, due to the uncertainty of the reservoir and the limitations of the commercial reservoir simulators, the...
Interfacial activity of SAGD PW endogenous surfactants, humic acids (HAs), and their interaction dynamics with naphtha-diluted Alberta oil sand bitumen (AOSB) present in model SAGD produced water has been addressed in the first part of this PhD thesis. Dynamic interfacial tension σ(t) between oil...
An Experimental and Numerical Study on Complex Behaviour of Cement Paste under SAGD Operating ConditionsDownload
During the exploration stage for oil sands mining or in situ thermal projects, many wells are drilled to recover core for resource assessment: these wells are referred to as stratigraphic wells. These stratigraphic wells are subsequently plugged with either thermal or non-thermal quality cement...
Heavy oils and extra heavy oils in Alberta that are currently extracted through thermal recovery primarily employ Steam Assisted Gravity Drainage (SAGD). Sand control devices (SCDs) such as Slotted Liners (SLs) and Wire Wrap Screens (WWSs) have been used extensively in wells producing from...
Different models have been proposed to describe two- and three-phase flow at the edge of a steam chamber developed during a SAGD process. However, two-dimensional scaled SAGD experiments and recent micro model visualizations demonstrate that steam-condensate is primarily in the form of...
Analytical Solution for SAGD with Consideration of Temperature Variation along the Edge of a Steam ChamberDownload
Steam-assisted gravity drainage (SAGD) is a widely-used method for heavy-oil and bitumen recovery. Analytical models were presented in the literature for bitumen-production rate and steam-to-oil ratio (SOR) for SAGD. They often overestimate bitumen-production rate substantially. Various...
Fischer—Tropsch gas loops have been in use for nearly a century, producing synthetic fuels and petrochemicals. Yet there still remain many opportunities to expand its uses, update the gas loop with new technology, as well as better understand at a fundamental level the way the products behave....
Model Predictive Control (MPC) is widely applied in the process industry nowadays. Chemical processes are corrupted by all kinds of uncertainties, such as measurement noises, disturbances and parameter uncertainties. Without consideration of uncertainties, conventional MPC will cause various...
Characterizing the Impacts of Shale Barriers and Lean Zones on SAGD Performance with Data-Driven Modeling TechniquesDownload
Performance of steam-assisted gravity drainage (SAGD) is influenced significantly by the distributions of shale barriers and lean zones, which tend to impede the vertical growth and lateral spread of a steam chamber. Reliable appraisal and prediction of SAGD require a comprehensive understanding...
Steam-assisted gravity drainage (SAGD) is an enhanced oil recovery (EOR) technology widely used in Canada. Data available in SAGD industrial processes contain valuable information for monitoring, soft sensing, control, and optimization. This thesis focuses on data mining and optimization in the...
