... Abstract In a miscible CO 2 flood, multicontact miscibility between the injected CO 2 and the reservoir fluid can be achieved at pressures greater than a minimum value. This minimum miscibility pressure (MMP) is a key parameter for assessing the applicability and design of a miscible gas...

.... Here the gas slowly breaks out causing foam to sit on the oil in the tank. This foam layer can be several feet thick, increasing the risk of the tank overflowing and causing a spill. storage tank firetube air emission emulsion co 2 prototype thermosyphon combustion efficiency burner...

... in Alberta. Finally, conclusions are drawn regarding the viability of the infrastructure proposed in this paper. Introduction Carbon dioxide (CO 2 ), a simple molecule composed of one carbon and two oxygen atoms, has been the subject of interest by the oil industry for over twenty-five years. Original...

... or individually, forother sectors. It was expected that this approach would create a synergisticindustrial activity between two or more industrial sectors. In 1995, the Synergy Workshop identified Carbon Dioxide (CO 2 as oneprolific by-product produced by more than one sector. Thus, the mass-producedCO 2 has...

... Saskatchewan). Three different methods were employed for determining MMP, namely, slim tube experiments, rising bubble apparatus (RBA) tests, and correlations. The solvents investigated included pure CO 2 , several blended or impure CO 2 streams, and a wellhead gas from the Steelman gas plant near the pool...

.../vaporizing phenomena, which are more complex than the traditional condensing phenomena. Similar interpretations apply to CO 2 processes. To capture these phenomena, current techniques involve the use of a sizeable number (4 or more) of pseudocomponents to represent the heavy fraction (e.g. CO 2 ) making...

... Abstract Vapor-liquid and liquid-liquid equilibrium data of mixtures of a Saskatchewan heavy oil and its constituent fractions with CO 2 were correlated by the Peng-Robinson equation of state. An excellent fit of the data was obtained by using optimized interaction parameters. Two predictive...

... Abstract An immiscible CO 2 slug and carbonated chase water enhanced oilrecovery process is being investigated at the shallow, light oil Salt Creek Field in Natrona County, Wyoming. This 100-year-old giant has had variousimproved recovery techniques, whose residual effects impact future...

... Abstract Numerical simulation of hydraulic fracturing with liquid CO 2 is discussed in this paper. Field experience indicates that CO 2 is a preferred fluid in sensitive reservoirs where there is a risk of formation damage with conventional treatments. Simulation of the process, which...

... Abstract For several years carbon dioxide (CO 2 ) has been added to fracturing fluids at concentrations of 100 to 500 cubic feet per barrel (18 to 90 m 3 /m 3 ), to assist in post-treatment clean-up. In some instances, this has eliminated swabbing after treatment. A new technique increases...

... another, reducing the residual oil saturation which results in improved oil recovery. The Petroleum Recovery Institute has focused attention on CO 2 as one of the fluids available as an injection agent in enhanced oil recovery processes. Use of the immiscible CO 2 process has been investigated...
