Benefits/Challenges of Polymer EOR depolyment

[Sesquipedalianist]

Hello All,

I am seeking your view on if there are any benefits or challenges you have seen in the deployment of Polymer flooding as an EOR option especially in heavy/waxy fields.

Cases such as deployment at the Mangala fields sound very good but I fear not enough information is availed to critically discuss if there's any challenges that would affect decision making.

Thanks
