In the present work, available direct and indirect methods for isobaric liquid heat capacity estimation are evaluated relative to experimental data. The study focuses on identification of systemic and random deviations between specific calculation approaches and experimental data, based on...

Oil sands bitumen is increasingly recovered by injecting steam into reservoirs using the energy intensive Steam assisted gravity drainage (SAGD) process. Interest in improving recovery and energy efficiencies have led to an interest in injecting light hydrocarbons along with or instead of steam...

Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Clays, in tailings, are a significant ongoing environmental concern in the mining and oil sands production industries and clay...

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...

Mixtures of colloids + non-adsorbing polymers + good solvents are well known to exhibit multiphase behaviors that are driven by the depletion flocculation mechanism where one phase, designated a colloid gas, is largely comprised of polymer and solvent, while the other phase, designated a colloid...

Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...

Commonly-used cubic equations of state (EOS) over predict the bubble point pressures (BPPs) for binary long-chain n-alkane + aromatic mixtures and frequently predict the incorrect phase diagram type. In this work, BPPs for 15 representative n-alkane + aromatic hydrocarbon binary mixtures were...

Sood, Sahil

Injection of carbon dioxide or low molar mass hydrocarbons to improve the productivity of oil wells has become a common practice. Such injectants are not fully miscible in reservoir fluids and oils leading to liquid-liquid phase behaviour in reservoirs, in production systems and surface...

Fine sand and clay particles arise naturally in diverse industrial and environmental remediation contexts. Organic compounds for example from oil production or oil spills can adsorb on their surface and influence their oil water interfacial behaviors. To isolate the impact of contamination and...

The nature and structure of asphaltene nanoaggregates are frequently the subject of debate and speculation in the literature. The continental asphaltene nano-aggregate model, characterized by the presence of alkyl chains on their surface, and the archipelago nano-aggregate model, characterized...
