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...
Primary oil recovery methods in Saskatchewan’s heavy oil basin extract 5 to 10% of the available resource with the vast majority left in the ground and recoverable only through Enhanced Oil Recovery (EOR) methods. Traditional EOR generates steam in surface facilities and injects it underground to mobilize the oil for production with considerable energy losses inherent in the process. R.I.I. Nor...
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...
In the process of heavy oil thermal recovery, the creep of strata can often be accelerated due to injection pressure, the temperature of steam, the structural characteristics of rock itself and other factors. However, the effect of creep in strata may cause various types of damage in underground mining, such as fracture or deformation of oil casings, and so on. The mechanism of fluid–structure ...
The thermal recovery method of steam flooding is one the most common development methods for heavy oil reservoirs. However, after multiple rounds injection development, composition crude and reservoir rock properties have changed greatly, which unfavorable subsequent enhanced recovery. It necessary to study distribution remaining reservoirs, clarify change characteristics components under diffe...
Since the 21st century, under background of steady social and economic development, China’s petroleum enterprises have developed rapidly, but in process oil well engineering, there are also low production, efficiency, order to improve recovery, it is necessary understand implementation effective solutions. This paper analyzes causes production efficiency combination with specific examples furth...
carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. depending on the operating pressure, the process might be miscible or immiscible. minimum miscibility pressure (mmp) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. the miscibility condition is determine...
