The study of local polymer on enhance oil recovery is to fine outs the capacity of local material to enhance oil recovery. Locally sourced polymer from starch and Ogbono (irvingia gabonensis) seed were used to increase viscosity of brine, since it has been known for long that the efficiency of a water flood can be improved by lowering the water oil mobility ratio in the system, such a change leads to better sweep efficiency and also more efficient oil displacement in the swept zone.

The experimental flow result show that viscosity range of 1.5(cp) to 3.0(cp) of the material used enhanced oil recovery and water breakthrough time retarded significantly while using local polymer. The maximum oil recovery recorded were 3.9cc, 2.8cc and 3.7cc for starch, ogbono and XCD polymer respectively at 2.0cp with corresponding breakthrough time of 44, 22 and 45 second respectively The good result may have resulted from the increase in the viscosity of the displacing fluid.
