Poor sweep efficiency in waterfloods can cause many barrels of recoverable oil to be bypassed and left in place. Sweep efficiency is a function of variations in permeability both horizontally and vertically. Many types of diverting agents have been used in an attempt to control paths taken by injected fluids, but all have been extremely limited in application. Recently, however, high-concentration solutions of certain polyacrylamides have proved highly effective in controlling both horizontal and vertical flood patterns by permeability adjustment. Although their use involves only a short- term treatment, normally without special well preparation or workover equipment, results have been long-lasting. This paper describes the use of these polymer materials to alter flood patterns and presents case histories demonstrating horizontal and vertical adjustment.
