"Recent application of the miscible sing displacement process as a method to increase recovery from petroleum reservoirs has resulted in a great deal of laboratory investigation, none of which provided conclusive evidence as to the amount of mixing taking place between the displacing and displaced fluids. This investigation attempts to provide a possible insight into the rate and degree of mixing of two fluids with respect to flow path transversed and the rate of advance of the fluids. The laboratory investigation consisted of displacing a fluid from a packed core with another fluid under completely miscible conditions.

Experimental evidence indicates that mixing between two miscible fluids does not necessarily stabilize with respect to volume composition although the length of the mixing zones might approach a constant value. Rate of flow has little effect on the volume of the mixing zone; however it was noted that the volumetric concentration of the displacing fluid in the mixing zone decreased with slower rates of advance.

It would be possible as well as practical to conduct investigations using fluid samples from a given reservoir prior to the instigation of a flood of this type. Results determined from such investigations could be used to predict behavior in the reservoir"--Abstract, page 1.
