... techniques for the determination of initial fluid saturations have also been used to attempt to determine initial fluid saturations with varying degrees of success. Another family of techniques, on which this paper concentrates, is the actual measurement of in-situ initial or swept zone fluid saturations...

This minimum miscibility...

... of microbubbles in altering PVT properties will be quantified through a series of PVT data. It is expected that the PVT properties are significantly altered due to the presence of asphaltenes, with a complex dependence on the asphaltene concentration. Also important is the nature of the gas phase present...

Due to the effects of fracturing treatments, such as fluid leak-off and fracture volume reduction upon closure, the polymer becomes concentrated on the formation face and within the proppant pack. At times the concentration of this polymeric filter cake becomes so high...

... Abstract At the 48 th Annual Technical Meeting, one of us presented a paper that showed that there was a possibility of making the SAGD process more efficient by adding a small concentration of a non-condensible gas such as methane to steam. For this to be effective the steam injection well...

Supersaturation are solutions that contain higher concentrations of dissolved solute than their equilibrium concentration. The causes of supersaturation may be due to: temperature fluctuation, pH alteration, addition...
