This paper discusses a simple computational technique for determining relative ganglion velocity in a pore and its implication to the formation and propagation of an oil bank. The approach is based on a simple theory of the movement of a discontinuous oil droplet (ganglion) through a model pore. The analysis, based on a simplified conical geometrical model, permits the development of expressions for relative velocity (velocity of the oil ganglion relative to the bulk liquid velocity) under various flow conditions. This parameter is essential for modeling waterflooding and/or EOR processes and facilitates the prediction of oil-bank movements. An example calculation illustrates the application of the concept. Results of the calculations indicate that faster oil-bank movements are attained when interfacial tensions (IFT's) are low and pressure gradients are high.
