Current and Past Projects
​
-
Chemical stabilized CO2 foams to reduce asphaltene precipitation, increased heavy oil recovery and sequestration from fractured carbonate reservoirs
-
CO2 for tight reservoirs
-
CO2 microbubbles for potential use as a safe and secure mode of CO2 injection into geological formations.
-
CO2 sequestration in fractured reservoir (Midale fractured carbonates) - Studied flow dynamics/diffusion of CO2/oil system was carried out and analyzed for EOR and sequestration, mechanism of extraction driven by diffusion/dispersion and miscibility for recovering lighter to heavier hydrocarbons during pressure depletion from fractured reservoirs.
-
Acid gas sequestration/EOR - Evaluated acid gas (CO2 + H2S), produced from the sour gas desulphurization process, and CH4 produced from the reservoir as a potential alternative to CO2 injection for EOR in the Zama field - Alberta.
-
Capillary and interfacial coupling phenomena during flow through porous media
-
CO2 sequestration in underground coal gasification (UCG)
CO2 Foam/Polymer Enhanced Foam - EOR and Sequestration
Solvent Injection into Heavy Oil Fractured Carbonate
Solvent sweeps the fracture - asphaltene starts to precipitate
Asphaltene precipitation at the matrix-fracture intersection
Severe formation damage due to asphaltene precipitation
At the end of Solvent Injection - dilution in the matrix
At the end of CO2 after Solvent (enhanced recovery and sequestration)
CO2 foam diverts the flow to matrix - minimum asphaltene precipitation
Emulsification and flow diversion
CO2-foam sweeps the matrix (enhanced recovery and sequestration)
