The largest polymer flood field in the Middle East is operating since 2010 with more than 40 polymer patterns and around 300 wells. Following a very diligent and complex operational procedures is essential to deliver the polymer properly to the reservoir. Throughout the past 12 years, this project went through several challenges such as injection uptime sustainability, polymer viscosity stability & polymer pumps uptime which have a direct ramification of the field polymer oil gain recovery. In 2022, the field realized the highest polymer oil gain since the project commenced, around 50% improvement in the oil daily rate compared to the past three years. These substantial results are consequences of several initiatives such as Polymer viscosity improvements due to better monitoring and improvements on troubleshooting reaction time, sustainable injection uptime with more than 85% though better maintenance & monitoring of the polymer pumps and PSUs and Polymer injection optimization: increasing polymer consumption in good performing patterns and reduce/stop in the lower ones. All these initiatives have led to significant improvements in the polymer utilization factor by around 40%. It is crucial to sustain a good performance and stable operation & injection uptime prior to the polymer phase 3 start-up where more than 400 infill wells are planned to be drilled to expedite the polymer recovery without polymer facility expansion. The objective of this paper is to shed light on the road map followed to restore value to this great project but also to provide insights to the newly introduced best practices that were developed by Marmul team and can be translated universally to any future polymer/cEOR project.
