the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

Displacement of oil and water in porous media of reservoir rocks is described by relative                      permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...

This paper will present a focused and personal history of physiologic monitoring, beginning with the discovery of modern anesthesia and its development from a technical practice to a scientific discipline. Emphasis will be on the essence of monitoring in the anesthesia evolution, and this work will attempt to answer the question of how to evaluate the impact of monitoring on patient outcome. Un...

background & aim : pulse oximetry is a frequently used and standard non-invasive method for monitoring oxygen (o2)-saturation in blood. many factors including dark skin and pigmentation may effect on rate of saturation of the blood oxygen absorbed by pulse oximetry. the effect of nail polish and/or henna color on blood oxygen has not been yet identified and the present study has been carried ou...

Pulse oximetry is a technique of fetal monitoring during labour based on non-invasive measurement of fetal arterial oxygen saturation. It has been shown in animal studies that metabolic acidosis occurred for a fetal arterial oxygen saturation below 30%. One of the main debates during initial experience in humans, was focused on the adequate cut-off for intervention (or non-intervention), and th...

Carbonate reservoir rocks of different pore structure have quite distinct and detectable 4D seismic signatures. Using three defined pore structure types (PST), these seismic signatures are correlated with the permeability patterns of carbonate rocks. In both the high-permeability PST3 and intermediate-permeability PST2 regions, gas injection is preferred than water injection for effective 4D se...

Our work developed oat of an interest in the behaviour of bacteria resident in benzene-, toluene-, ethylbenzeneand xylene(s)-(Le., BTEX)-contamihated aquifers. We observed that such environments are oxygen-limited, yet continueus monitoring over extended periods suggested that BTEX contaminants were disappearing and the contaminant plume may be diminished. Such observations suggested that signi...
