Paper presented at the SPE Improved Oil Recovery Symposium, April 24–28, 2010
Paper Number: SPE-130007-MS
... Abstract The ability to select low-cost, high-performance surfactants for a wide range of crude oils and reservoir conditions has improved dramatically. There are thousands of possible combinations of chemicals and components (including differing salinities, hardness, and oil concentrations...

... . And it is this term that increases most rapidly when oil MW goes up. The molecular weight of a crude oil is usually relatively high, due to the presence of heavier components, and as a consequence the value of E tail-oil will be lower and obtaining high solubilization will be more challenging. A surfactant...

Paper Number: SPE-129978-MS
... Chemicals and used as received. Polymer Abstract The ability to select low-cost, high-performance surfactants for a wide range of crude oils under a wide range of reservoir conditions has improved dramatically in recent years. We have developed surfactant formulations (surfactant, co-surfactant, co...

... % for non waxy-liquid crude and 13.0 % for waxy-gelled crude. These findings from the laboratory were further validated by production optimization using Wellflo. The thermochemical method utilizing acidized amines is simple and yet experimentally proved to be effective in solving the wax related problem...

Paper presented at the SPE/DOE Symposium on Improved Oil Recovery, April 22–26, 2006
Paper Number: SPE-99752-MS
... Abstract Application of cyclic solvent injection into heavy and viscous crude oil followed by in-situ combustion of heavy residues is explored from a laboratory perspective. The solvent reduces oil viscosity in-situ and extracts the lighter crude-oil fractions. Combustion cleans the near well...

... an important share of your oil requirements. In 1980, direct exports to the United States averaged nearly 500,000 barrels of oil per day, more than half of which were refined products. When Venezuelan crude oil that is refined in the Caribbean and then shipped to the United States is included, about half...

... in the model, scaled to provide the proper ratio of viscous flow to gravitational flow, outweigh all other factors affecting mechanical mixing. As a result mechanical mixing is enhanced in the models. Shelton and Schneider's 10 work on the displacement of crude oil by solvents and carbon dioxide led...

... net recovery of crude oil is theoretically possible for in-situ combustion, this factor may also be offset by using coal instead of lease crude for generating steam. Introduction Thermal recovery of crude oil is an established art in the petroleum industry. How is an art to be taught in a petroleum...
