Alaska holds more than 68 billion barrels of proved oil reserves and 36.7 trillion cubic feet natural gas with some special conditions such as proximity to permafrost, making Alaskan petroleum unique. The low temperature in shallow reservoirs prohibited hydrocarbons’ ideal maturation, thereby generating several heavy viscous accumulations this state. This also limits the enhanced recovery (EOR)...

Over the years, naturally occurring CO2 has been used in many enhanced oil recovery (EOR) projects United States [...]

Enhanced oil recovery (EOR) techniques can significantly extend global oil reserves once oil prices are high enough to make these techniques economic. Given a broad consensus that we have entered a period of supply constraints, operators can at last plan on the assumption that the oil price is likely to remain relatively high. This, coupled with the realization that new giant fields are becomin...

Microbial flooding is a new enhanced-oil-recovery technology for the petroleum industry. In this study, strain of Bacillus subtilis named SL-2 was isolated from oil-well-produced fluid. B. produces lipopeptide surfactin. The fermentation broth contains biosurfactants (1.2 g/L) with good surface and interfacial activities. Adding 7% to water reduces its tension 72 33.9 mN/m between hexadecane 40...

Polymorphum gilvum SL003B-26A1(T) is the type strain of a novel species in the recently published novel genus Polymorphum isolated from saline soil contaminated with crude oil. It is capable of using crude oil as the sole carbon and energy source and can adapt to saline soil at a temperature of 45°C. The Polymorphum gilvum genome provides a genetic basis for understanding how the strain could d...

Nanoemulsions are a class of emulsions with a droplet size in the range of 50–500 nm and have attracted a great deal of attention in recent years because it is unique characteristics. The physicochemical properties of nanoemulsion suggests that it can be successfully used to recover the residual oil which is trapped in the fine pore of reservoir rock by capillary forces after primary and second...

Purpose. To develop a technology to increase the oil recovery of formations using injection polymer compositions. Methodology. For this study, practical methods were used such as enhanced stimulating technologies, systems based on water-soluble acrylamide, and emulsion-polymer technology. achieve conformance control, which was prerequisite for testing, thorough selection wells carried out, well...
