... Publication Rights Reserved Abstract A method to predict the reserves and performance of a waterflood utilizing peripheral injection is developed. It is a modification of the method used by Prats, et al. to predict the reserves and performance of a five-spot waterflood system. Both...

... of waterflooding, larger quantities of water have been both produced and injected. The bacteria problem was originally ignored in many of these operations, and only when serious problems were encountered did the oil industry become aware of the effect of microorganisms in water systems. With the recognition...

... water drives and imposed water floods. For floods at constant pressure, the effects of the presence of free gas on waterflood behavior may be evaluated from tests on short core samples. However; it may be desired to estimate these effects when the results of appropriate flow tests are not available...

... injection equipment. Fracturing often makes profitable oil recovery possible in a reservoir which otherwise could not be considered commercial. Such a situation may occur after prolonged waterflooding or early in the life of a water flood project. Selecting Wells to be Fractured Several factors should...
