The use of enhanced oil recovery methods to improve oil productivity has grown and come to stay in the industry. This is as a result of its ability to improve productivity and sweep efficiency. Waterflooding, the most widely used method to recover oil becomes less effective when the mobility ratio is unfavorable and the displacement efficiency is low. This leads to viscous fingering or channeling that leads to significant bypassing of residual oil. Augmenting injected water with polymer will

This property is not a correct reflection of the sweep displacement. Polymer's non-Newtonian behavior needs to be taken into account for the successful design and evaluation of polymer flooding projects. The objective of this work is to study the performance of polymer rheology on oil recovery under different fluid and rock properties. This project uses ECLIPSE 100 to study the performance of polymer flooding on oil recovery. Sensitivity runs was made on polymer concentration, polymer injection rate, rock wettability, polymer rheology, heterogeneous reservoir, stratified reservoir with crossflow. Based on the simulation studies and the hypothetical model built, Polymer flooding and Original Research Article _________________________________________________________________________________
