... been developed. Many parameters believed to be pertinent have been investigated, such as connate water saturation, relative permeability saturation relations, sample wettability, and waterflood scaling (including the effect of such variables as pore size, flow rate, viscosities and interfacial tension...

... be employed to solve it. Finite difference method is used to discretize the equations. The grid is shown in Figure 3 . Because of the nonlinearity, these equations are solved fully implicitly through iteration. Abstract Water injectivity decline is a very common phenomenon in waterflooding fields. Most...

... the changes are roughly 10 percent of the signal and twice as large as the system noise level. It is therefore feasible to track injected water following a CO 2 flood but probably not the CO 2 flood itself. Note that only part of the anomaly is visible in the waterflood example. The effect of this partial...

We found that the injectivity of the chase water zone was comparable to the initial waterflood injectivity, and increased as the trapped CO dissolved. The injectivity of the CO-rich zone was significantly...
