... Abstract As production from oil-bearing reservoirs matures, the need for enhanced oil recovery becomes increasingly important. In many of these reservoirs, waterfloods have been implemented and are presently approaching their economic limit in terms of producing water-oil ratio. One...

... Abstract Oil production in the province of Alberta will be increasingly dependent on Enhanced oil recovery (EOR) technology in the next decade. Successful implementation of an EOR process requires a thorough understanding of the reservoir flow behavior. The most difficult parameters to assess...

... of initial oil-in-place. Thermal methods, especially in-situ combustion, appear to be the most promising enhanced oil recovery technique for these reservoirs. An understanding of the reservoir geology and oil chemistry is essential for screening, designing and application of the in-situ combustion process...

... by EOR methods (1). Techniques for enhancing oil recovery which have shown significant promise for this remobilization include thermal methods, carbon dioxide and hydrocarbon miscible processes, and chemical flooding. Of all these, chemical flooding, although the most complex, seems to hold the most...

... and maintenance costs. Therefore, it is not always easy to find the optimum solution in each specific application of an ASU. All these above mentioned criteria are also valid in Nitrogen-Generators when only Nitrogen for enhanced oil recovery is produced. Since the Nitrogen is produced most economically...

... Introduction Enhanced oil recovery by gas injection has been practiced by the oil industry for years. In immiscible recovery projects, the injected fluid maintains reservoir pressures and drives the oil towards producing wells. In miscible projects, the injected fluid and oil dissolve in one...

... Abstract The need to understand various mechanisms governing fluid-fluid displacements associated with enhanced oil recovery provides the motivation for this study. These displacements are characterized by fluctuations in flow due to interfacial phenomena such as Haine's jumps, droplet break...
