The idea of injecting low salinity water into a petroleum reservoir is not novel and was often used in the 70’s prior to the injection of surfactant. Yet, recently it was shown that simply injecting sufficiently low salinity water improves oil recovery (LoSalTM). Many possible mechanisms concerning Low salinity waterflood have been proposed in the literature. This paper describes an experimenta...

Enhanced oil recovery (EOR) has been identified as a method of sequestering CO2 recovered from power plants. In CO2flood EOR, CO2 is injected into an oil reservoir to reduce oil viscosity, reduce interfacial tension, and cause oil swelling which improves oil recovery. Previous studies suggest that substantial amounts of CO2 from power plants could be sequestered in EOR projects, thus reducing t...

In this study, anesthetic effects of five different concentrations of 2-phenoxyethanol (0.2, 0.3, 0.4, 0.5 and 0.6 ml/L) and clove oil (0.50, 0.75, 1.00, 1.25 and 1.50 ml/L) on rainbow trout (Oncorhynchus mykiss) were studied at temperatures 7, 13 and 18ºC. For this purpose, 900 fish (39.08 ± 1.13 g and 15.48 ± 0.21 cm) were used in the experiment. Induction time of 2-phenoxyethanol and clove o...

Claude ZoBell’s recognition of the influence of microorganisms in the ecology of petroleum bearing environments was all encompassing. This translated into a unique contribution over the entire span of the oil industry. Many of his publications in the 1940s and 1950s discussed the key role of microorganisms in the diagenesis of hydrocarbon products. At a time when the industry was treating the s...

Recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. In particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...

Wheat germ oil was added to a larval liquid diet for rearing Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) to optimize fruit fly quality. Effects of various concentrations of wheat germ oil at 0.04, 0.07, 0.15, 0.30, and 0.66% and their possible mode of action were evaluated. Results suggest that addition of wheat germ oil does not affect pupal weight, larval developmental period, adult e...

Enhanced oil recovery (EOR) has been identified as a method of sequestering CO(2) recovered from power plants. In CO(2)-flood EOR, CO(2) is injected into an oil reservoir to reduce oil viscosity, reduce interfacial tension, and cause oil swelling which improves oil recovery. Previous studies suggest that substantial amounts of CO(2) from power plants could be sequestered in EOR projects, thus r...

Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...

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...
