Orr, F M - Theory of Gas Injection Processes Episode 3 pptx

... L 1 is the fraction of the one mole of mixture that is phase 1. Elimination of x i1 from Eq. 3. 4 .3 gives x i2 = z i 1+L 1 (K i − 1) ,i=1,n c . (3. 4.4) Similar elimination of x i2 using Eq. 3. 4.2 gives x i1 = K i z i 1+L 1 (K i − ... generalization [32 ] of the well-known problem of displacement of oil by water (solved first by Buckley and Leverett [10], see Lake [62, pp 13...

... oil and injection tie lines can be determined easily from the magnitude of K 2 or equivalently, from the location of the envelope curve for systems with constant K-values. The vast majority of gas/ oil systems ... must have condensed from the injection gas because no CO 2 is present in the initial fluid. It is that trans- fer of intermediate component from the injection gas...
