The challenges in improving oil recovery on carbonate reservoir which still have high
remaining reserves are naturally fractured and heterogeneous properties of the rocN. Those
factors contribute to selecting the applicable EOR method. Polymer injection is one of the
best candidates for the EOR method in a sweeping efficiency in carbonate reservoir
implementation. This paper's main purpose is to observe the best polymer concentration to
produce the highest oil recovery. The sensitivity of some scenarios is approached by using …
