RI 5713 Effects Of Hydraulic Fracturing In Oklahoma Waterflood Wells ? Introduction And Summary

A comprehensive study of the effects of hydraulically fracturing water-flood wells in Oklahoma has been made by the Federal Bureau of Mines. This report presents results of that study and an analysis of some of the factors governing the results of fracture treatment on waterflood properties. Originally, hydraulic fracturing was used to stimulate oil production from old wells producing by primary methods, and its application to water-flooding was regarded with skepticism by most producers. However, since 1953 the number of fracture treatments of both oil and input wells in waterfloods has increased steadily. Hydraulic-fracture treatments in waterfloods have generally been successful in stimulating production from oil wells and increasing the rate of injection into input wells. Hydraulic fracturing has enabled several producers to turn probable failures into economically successful projects.
