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...

in this paper, the output power behavior of the wave-guide cw-co2 laser versus efficient parameters of laser performance was investigated. the output power variation versus the discharge current, the pressure and the gas mixture ratio was studied and optimized. the maximum output powers of 6 and 14.5 w were respectively obtained at operating pressures 78 and 50 mbar in two tubes of 3 mm same di...
