Prediction of recovery in miscible displacement in porous media using the dispersion equation
The one-dimensional dispersion equation is used to predict the fractional recovery of displaced fluid as a function of PV of displacing fluid injected in miscible displacement in a porous pack. Two solutions are used corresponding to infinite and semi-infinite packs. The Peclet number is found to characterize the shape of the recovery curve for both solutions. It is found that the predicted recovery using the solution for a semi-infinite medium corresponds more closely to the literature data. Data of several workers are analyzed and the corresponding Peclet numbers determined. An empirical graphical relationship is found between the Peclet number and the mobility ratio of the 2 fluids. This relationship could be used to estimate the Peclet number and hence the recovery curve for a particular miscible displacement. (14 refs.)
