... Abstract Many examples of reaction-diffusion processes are encountered in enhanced heavy oil recovery applications. A typical instance of such a process is when a chemical diffuses through a fluid column and then undergoes reaction with another chemical species. The reaction products further...

... or crushed carbonate rock and clay were studied using Thermogravimetric Analyzer (TGA) and Differential Scanning Calorimeter (DSC) techniques. The reactions were carried using air enriched with different percentages of oxygen. Two sets of experiments for the combustion of crude oil samples were carried out...

... Abstract In-situ combustion is a subject of continuing interest due to its rich interplay of flow, mass/heat transfer and reactions. The process complexity, however, has precluded its thorough understanding. In this paper, we provide some analytical results and pore-network simulations...

..., by using a variable fre- quency unit at a facility in North Carolina. Results were promising despite the rapid screening which was employed. Experimental variables included additives, reaction time, and frequency. The addition of activated carbon produced an oil that met pipeline specifications...

... Abstract The thermal recovery of heavy oil and bitumen from cool reservoirs via the injection of steam and hot fluids results in geochemical systems that are far from equilibrium. As a result, mineral and other solid grains in the reservoir may react with the injected fluid. These reactions...

Because it was believed that caustic inhibits oxidation reactions as evidenced by a reduction in or absence of coke formation, and allows the oil to upgrade by thermal cracking via a free radical mechanism, a systematic study was undertaken to investigate the effect...

To compliment the experimental investigation, the thermal numerical simulator STARS has been applied to the in-situ combustion process by incorporating reaction kinetics for Athabasca oil sand.
