Robust Gaussian Process Regression and its Application in Data-driven Modeling and Optimization
DownloadFall 2015
Availability of large amounts of industrial process data is allowing researchers to explore new data-based modelling methods. In this thesis, Gaussian process (GP) regression, a relatively new Bayesian approach to non-parametric data based modelling is investigated in detail. One of the primary...

Steam-Solvent Coinjection for Bitumen Recovery under Reservoir Heterogeneity with Consideration of Water Solubility in Oil
DownloadFall 2017
The main objective of this research is to determine if expanding solvent-steam assisted gravity drainage (ES-SAGD), wherein a small quantity of a condensable solvent is coinjected with steam, can be a better alternative to SAGD in highly heterogeneous formations. Specifically, three previously...

Lignin is one of the most plentiful natural polymer on the earth, produced on a large scale as the waste of pulp and paper industries. The inherent properties of lignin, such as nontoxicity, cost-efficiency, and biocompatibility, make it suitable for the green modification of bulk and surface...

Techniques for fast screening of 3D heterogeneous shale barrier configurations and their impacts on SAGD production behavior
DownloadSpring 2020
Steam-assisted gravity drainage (SAGD) recovery process is strongly impacted by the spatial distributions of heterogeneous shale barriers. Though detailed compositional flow simulators are available for SAGD recovery performance evaluation, the simulation process is usually quite computationally...

The quantification of fines migration in the vicinity of sand control screens in SAGD wells is of paramount importance to operating companies, who require the wells to operate under optimum conditions for a period of 10-15 years. Fines migration can lead to the plugging of pore spaces...

Spring 2021
Alberta’s oil sands deposits are the third-largest proven crude oil reserve in the world. However, only 20% of the bitumen in Alberta’s oil sands are shallow enough to be recoverable by surface mining techniques; the remaining 80% can only be extracted using in-situ techniques that involve the...

Steam assisted gravity drainage (SAGD) method is the main oil extraction method in Alberta that produces a huge volume of waste water. This thesis is focused on investigating the viability of membrane processes, as emerging water treatment technologies, for treatment of SAGD produced water. Three...

Wave Speed Measurements of Grosmont Formation Carbonates: Implications for Time-Lapse Seismic Monitoring
DownloadFall 2019
The Grosmont Formation is a Devonian-aged carbonate platform complex that is estimated to hold over 64.5 billion m3 (406 billion bbl) of bitumen in place, accounting for a significant portion of Canada’s total hydrocarbon reserves. Despite this, the Grosmont formation has largely been undeveloped...
