Excerpt from Studies of Waterflood Performance, Vol. 3: Use of Network ModelsObviously it would be a great advantage to have a quantitative value for the recovery factor before beginning a secondary recovery operation. The economics of the project could then be predicted with reasonable certainty.As it turns out, much effort has been directed to this purpose (muskat, 1949, Ch. 12, 14) through the development of core analysis, the study of laboratory models, and the use of various analytic methods of inquiry. Two categories of difficulties are encountered in any attempt to predict recovery factors, how ever. First, it is not practical to stipulate the exact character of the reservoir system with regard to initial and boundary conditions of fluid saturations and pressures, nor can the variations of permeability and porosity be specified. Second, the inherent non-steady nature of secondary recovery processes makes exact solutions largely intractable.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
