A Multi-Objective Optimization Workflow for Steam-Alternating-Solvent Heavy Oil Recovery Process DesignDownload
The steam alternating solvent (SAS) process involves multiple cycles of steam and solvent (e.g. propane) being injected into a horizontal well pair to produce the heavy oil. Companies are interested in these solvent-based methods, as they entail a smaller environmental footprint with reduced...
Development of Solvent Selection Criteria Based on Diffusion Rate, Mixing Quality, and Solvent Retrieval for Optimal Heavy-Oil and Bitumen Recovery at Different TemperaturesDownload
Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of the process. Attention has been given to solvent injection for this purpose and it has been observed that high recoveries are achievable when combined with steam injection. Heavier (“liquid”) solvents...
Unconventional oil (mainly heavy oil, extra heavy oil and bitumen) represents a significant share of global oil reserves. Due to their high viscosity, efficient recovery of oil from these reserves is challenging and remains an issue of ongoing global research. Thermal recovery methods are...
In this work, the phase behavior of Athabasca bitumen + CO2 and Maya crude oil + CO2 is briefed. A literature review is presented on the previous research works (mostly experimental studies) done on CO2 + heavy oil and similar mixtures. Important aspects of phase behavior such as type of phase...
The rheological properties of heavy oil and bitumen depend on factors such as temperature, pressure, diluent type and diluent composition, as well as sample shear and thermal histories and shear conditions during measurements. Each of these factors can affect the value of apparent viscosity...
Natural and Drilling induced Fractures in the Grosmont Formation, Alberta: Implications for the State of StressDownload
The Devonian Grosmont formation is a huge heavy oil carbonate reservoir located in northeastern Alberta that has an estimated 64.5 x 〖10〗^9 m^3 initial oil in place. This thesis will focus on issues related to the in situ state of stress and the natural fracture statistics within the Grosmont...
