Polymer flooding: Current status (2023) and future directions

Article: "Polymer flooding: Current status and future directions"

Reviewer Outline: This article offers insights into the current state of polymer flooding for enhanced oil recovery (EOR). It discusses the dominance of HPAM as the primary polymer and explores the requirements for alternative polymers and mobility-control methods. The significance of large polymer banks, design of injected polymer viscosity, and the role of fractures and horizontal wells in improving injectivity are highlighted. Operational improvements to enhance mechanical and oxidative stability are described, along with factors affecting polymer retention. The review also highlights unresolved issues and future directions in polymer flooding.
