.... According to the experimental results, we developed hypotheses to understand the bitumen/illite and bitumen/kaolinite interactions for SAGD. Because of the high water-wetness of illite, illite particles first interact with water. This interaction results in cementation and forms illite lumps with sand...

... of Athabasca bitumen supplied by Japan Canada Oil Sand Ltd. (JACOS). These tests were part of a larger program of combustion-tube tests performed by the In-Situ Combustion Research Group (ISCRG) under the auspices of the Alberta Ingenuity Center for In-Situ Energy (AICISE). The tests were premixed and carried...

...Leah Miller Guindon Caprock-integrity issues have been brought to the forefront with recent documented steam and bitumen leaks making their way to the ground surface, forcing the Alberta Energy Regulator (AER) to place a moratorium on the licensing of shallow thermal in-situ oil-sand projects...

...Ibrahim Inamah Abu; R. Gordon Moore; Sudarshan A. Mehta; Matthew G Ursenbach; Donald G Mallory; Pedro Pereira Almao; Lante Carbognani Ortega Summary Dry and normal wet combustion-tube tests were examined to study the upgrading potential of Athabasca bitumen supplied by Japan Canada Oil Sand Limited...

...Harvey Yarranton; Hamad Reza Motahhari; Florian Schoeggl; John (Zhihong) Zhou Summary One of the issues for the pipeline transportation of diluted bitumen (dilbit) is the fate and behaviour of the dilbit if it is spilled in freshwater systems; in particular, the evaporation rate and the change...

... on estimation of mass-transfer parameters using pressure-decay data of carbon dioxide (CO 2 ), methanw(CH H ), and nitrogen (N 2 ) dissolution in Athabasca bitumen at two different temperatures were found to be negligible, considering the gas/oil-interface resistance on calculated values of diffusivities...

... for 100- kHz frequency. Introduction Viscosity is a major obstacle in the recov- ery of bitumen in oil-sand reservoirs. Ther- mal recovery is considered the most ef- fective method for lowering viscosity, and steam-assisted gravity drainage (SAGD) is the most promising thermal recovery tech- nique applied...

...Leah Guindon The objective of this study was to develop reaction-kinetics models that can be used to describe the reactions of hydrocarbon fractions at various temperature conditions during the in-situ combustion (ISC) of Athabasca bitumen. In this work, a set of improved kinetic models—including...

...Leah Guindon Research from this paper provides insight into the physical and chemical consequences of steam-assisted recovery of heavy oils and bitumens from sedimentary-rock reservoirs and reveals that geological and geochemical context is an essential consideration. To study mineral effects...

...Leah Guindon Bitumen recovery is affected by the water-soluble acid species located in the working area, and this paper takes a look at those interactions and the outcomes each may have on oil-sands recovery. Varying parameters on recovery (e.g., oil-sands components, physicochemical and dielectric...

...Mohammad Kariznovi; Hossein Nourozieh; Jalal Abedi The heavy-oil- and bitumen-recovery processes mainly intend to reduce the oil viscosity at the reservoir; therefore, the production and pipeline transportation of such viscous fluids require specific data on the viscosity and density of raw bitumen...

... ST98-2013). The Pike 1 Project is a joint venture between Devon Canada Corporation (operator) and BP Canada Energy Group ULC. The Pike 1 Project is currently under a multiyear appraisal program to evaluate the McMurray bitumen resources that are amenable to steam-assisted gravity drainage(SAGD...

...Khosrow Naderi; Tayfun Babadagli Summary This work examines the steam-over-solvent injection in fractured reservoirs (SOS-FR) method--which was originally suggested for heavy-oil/bitumen recovery from oil-wet fractured reservoirs—for unconsolidated sands containing heavy oil. One possible...

...Bruce Roberts; Tarek Hamida Summary A new recovery process, thermal-assisted gravity drainage (TAGD), is described for the recovery of bitumen from heterogeneous carbonate reservoirs. The process is shown to be thermally efficient in lower-porosity formations and is less impacted by the complex...

...Moslem Hosseininejad Mohebati; Daniel Yang; Jeff MacDonald Summary The Grosmont formation, a carbonate reservoir in Alberta, Canada, has 400 billion bbl of bitumen resource, which is currently not commercially exploited. The carbonate reservoir is karstified by groundwater and tectonically...

...Daniel Yang; Moslem Hosseininejad Mohebati; Steve Brand; Caralyn Bennett Summary Bitumen production from the Grosmont formation is enabled by bitumen-viscosity reduction caused by heating with steam, and is driven by three processes: thermal expansion, gravity drainage, and spontaneous imbibition...

...Mohsen Zirrahi; Hassan Hassanzadeh; Jalal Abedi Summary Viscosity is an important transport property for engineering design and simulation of bitumen production and transportation. During the production of bitumen with solvent injection, steam-assisted gravity drainage, or expanding solvent steam...

...Hamad Motahhari; Florian Schoeggl; Marco Satyro; Harvey Yarranton Summary Accurate predictions of heavy-oil and bitumen viscosity as a function oftemperature, pressure, and composition are required for the design of thermaland solvent-based recovery methods. In this case study, the applicability...

...Varun Pathak; Tayfun Babadagli; Neil Edmunds Summary With the decrease in conventional oil and gas reserves throughout the world and an ever-increasing demand for fossil-fuel-based energy and resulting high oil prices, focus has been shifting to unconventional and heavy oil and bitumen. Grosmont...

... parameters to obtain mixture viscosity. The three parameters were correlated to component molecular weight (MW); therefore, a gas-chromatographic assay is the only required input apart from the temperature and pressure. The methodology was developed from a western Canadian (WC) data set of two bitumens, one...
