... of the polyacrylamide through the rock was much less than anticipated. Performance of a polymer injection well is compared to several J-Sand water injection wells. It is evident that injectivity is greatly reduced with polymer injection; the loss in injectivity approximates that which is expected when the mobility...

... system was initiated late in the Fall of 1981. The results of the off-pilot mini-injectivity test indicated: that Shannon injection well characteristics can be changed by polymer injection; that polymer solution concentration, crosslinking and complexing can be varied for specific desired injection...
