Description
Yunqian Long and co-authors characterize a weak gel for squeezing more oil from reservoirs after polymer flooding, in this 2024 Europe PMC paper. Long polymer floods worsen reservoir unevenness, stranding oil. Their gel links chromium acetate with polyacrylamide into a network that tightens as polymer content rises.
The gel resists shear better than plain polymer solution, flows like a pseudo-plastic fluid, and is more elastic than viscous, with elasticity growing over crosslinking time. In sandpack tests it controlled flow and recovered more oil than polymer solution alone, especially in strongly uneven, low-permeability rock. Added recovery climbed steeply as the permeability contrast between layers increased.
