... and then, it was reduced to 30% when polymer flooding was extended for 5 injected PVs. The RRF values were moderately low in both core samples (fractured and unfractured); however, a slight increase in RRF appeared in the fractured core sample due to polymer retention in matrix region. This investigation is one...

... achieved success with waterflooding but currently, a continuous decline is observed. Polymer flooding is proposed as a solution in these cases. The pre-salt fields are still ramping up production at very high rates. Hence, as an alternative, in those reservoirs, CO 2 -WAG might be applied in the near...
