... at the same temperature and pressure. Another example is the effect of water on bubblepoint of water/hydrocarbon mixtures. It is a common practice that the bubblepoint measurements are conducted on an H 2 O-free basis. It will be revealed in this paper that the three-phase bubblepoint pressure of some...

... are unlikely in hydrocarbon reservoirs, even where clay-size particles are present, because the fmest pores are occupied by connate water. Measured dewpoint or bubblepoint pressures were found to be independent of the presence of porous media. Trebin and Zadora 5 claim that the initial condensation...

These values are necessary to compute oil reserves or for calculations involving flow through pipes or porous media. A review of the correlations is provided, along with the results of calculations made on 31 individual crude oil...

Also, solvent/oil phase behavior predictions at reservoir pressures—i.e., the accurate construction of the gas/liquid two-phase envelopes in pseudoternary diagrams—closely matched the multicomponent data...
