In the first use of core analysis data to measure the effect of permeability stratification on waterflood predictions, Dykstra and Parsons used the commonly found log normal permeability distribution of reservoir rock. Their calculation procedure to predict future performance of a waterflood orders permeability layers in descending order, and requires all layers to be a constant thickness. Results of a series of waterflood lab tests by Dykstra and Parsons show that recovery in a stratified system is a function of the ratio of the mobility of the driving phase (water) to the mobility of the driven phase (oil). Procedures for predicting recovery in a layered reservoir allow mobility ratios other than unity to be considered. Equations for coverage and producing water-oil ratio are given.
