Spring 2014
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...

An Experimental and Numerical Study on Complex Behaviour of Cement Paste under SAGD Operating Conditions
DownloadSpring 2020
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 Chamber
DownloadSpring 2017
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...

The warm vaporized solvent injection process has been proposed as a more environmentally friendly alternative to steam-based technologies for bitumen recovery. The process typically involves injecting heated solvent vapor into a horizontal injector; the solvent condenses and dissolves into...

Characterizing the Impacts of Shale Barriers and Lean Zones on SAGD Performance with Data-Driven Modeling Techniques
DownloadSpring 2016
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...

Data-Driven Approaches to Estimate the Impact and Presence of Shale Barriers in SAGD Reservoirs
DownloadSpring 2019
Steam-assisted gravity drainage (SAGD) is one of the most successful in-situ techniques and has been widely adopted for heavy oil and bitumen recovery. Steam chamber development and SAGD production performance are highly sensitive to the reservoir heterogeneity, thus characterizing shale...

Spring 2014
Evaluation of steam-assisted gravity drainage (SAGD) performance that involves detailed compositional simulations is usually deterministic, cumbersome, expensive (manpower and time consuming), and not quite suitable for practical decision making and forecasting, particularly when dealing with...

Oil sand reservoirs play an important role in the economy of Canada due to their significant recoverable reserves. Due to the high viscosity of the oil in these reservoirs, conventional methods cannot be used for production. The steam-assisted gravity drainage (SAGD) method is an efficient way of...
