The higgins-leighton mathematical model was tested by comparing the prediction of performance with observed performance in a mature water flood in the dominguez field in southern California. Although accurate reservoir data were not available, the first match was a reasonably good first approximation. For example, the deviation between the calculated and actual recovery for the first 5 years averaged above 15 bbl/acre-ft. Study of the results of the first match indicated that it could be improved by using revised estimates for two variables, interstitial water saturation and permeability distribution. By trial and error with successive revision of these two variables, values were obtained which gave an excellent match. The deviation between the calculated and actual recovery averaged 4 bbl/acre-ft. The results showed that the reservoir contained more mobile water at the beginning of the flood than suspected by the operator and that a few high-permeability layers had produced the major part of the oil produced from the 155-ft section.
