SHEAR RESISTANT, HIGH INJECTIVITY POLYMER TECHNOLOGY
Designed specifically for harsh Enhanced Oil Recovery (EOR) mobility control applications, the Excelceor technology provides more oil, faster, with less polymer compared to traditional polymer floods. This field-proven and customizable technology addresses the problems in shear-inducing environments through a unique triggering mechanism.

Polymer flooding is an established technology (HPAM) to improve mobility ratio and sweep efficiency, with limited use offshore due to challenges:
Excelceor is a patent-pending polymer technology developed to address offshore challenges. Successful laboratory and scale pilot trials prove benefits over traditional HPAM:
For the past five years, Nalco Champion scientists and engineers have worked to develop and optimise this technology. Internal and third-party laboratory and pilot testing results verify improvement over conventional HPAM. Refer to 2017 EAGE paper Enhanced Polymer Flooding – Reservoir Triggering Improves Injectivity and Eliminates Shear Degradation.
Laboratory Tests
Pilot Scale
The onshore field trial was a joint effort among Nalco Champion, BP and OMV and was completed with no recordable safety incidents.
All KPI goals of the field trial were met or exceeded:
