... carry gas flow. According to published gas tracer studies (Friedmann et al., 1991; Gillis and Radke, 1990; Tang and Kovscek, 2006), the fraction of gas trapped within a foam at steady state in sandstones ranges from about 85 to 99%. The large gas blockage reduces the relative permeability of the gas...

... is an important descriptor of lithofacies and can help distinguish between rock-types that have a similar texture on grey- scale. For instance, cemented sandstones can be easily distinguished from the non-cemented ones using color information when compared to a case where only grey- scale values are used. We used...
