... of 512,000 bbl. of oil had been recovered through primary production and a small dump flood. Carbonated waterflooding was applied beginning in April, ~ 1,2 1950, with spacing on a 10-acre five-spot pattern Increased water injectivity was noted immediately. At the start, average injection rate was 163 bbl...

... water, injection rates has been a problem at Benton and is a problem to many waterflooding projects. Inability to maintain desirable injection rates is generally the result of plugging by precipitates in the injected water, skin effects incurred during completion, and limited res- ervoir capacity...

... hydraulic fracturing has im- proved injection rates and well performance, with no indication to date o~ premature water break- through. Fracturing also has proven of great value to producing wells which have shown abnor- mally low total fluid production rates, due to wellbore damage or blocking. No definite...

... that the well was not satisfactorily responding, pressure-wise, tQ injection. Of the group of 38 water wells, seven did not respond satis- factorilY and had to be selectively plugged. Water was first introduceil. into the Starit property in November, 1953. By November, 1954, the maximum injection rate had been...
