Paper Number: SPE-18092-MS
... of an unconfined 5-spot on a 200 m spacing was initiated in May 1986. After the injection of a water preflush of 0. 23 PV, a polymer slug of 0. 63 PV and a water postflush of 0.34 PV, the total oil production was 59% of STOIIP. The injection of polymer resulted in a sharp increase in oilcut in all four wells. From...
