Paper Number: SPE-200669-MS
... occurred during the coldest days when Hexs temperature was raised to 160°C to increase heat to treat fluids. Meanwhile, it also suffered antagonistic effects from the EOR polymer. A dozen new inhibitor chemistries were studied including polymers and phosphonates. Polymeric inhibitors had higher thermal...

This paper experimentally demonstrates potential changes to inhibitor adsorption from a polymer EOR project by demonstrating the complex interactions between HPAM and phosphonate scale inhibitors with respect to adsorption. This work presents a detailed coreflooding programme, supplemented with bottle...

Our laboratory studies indicate that a polymeric compound containing amide functionality showed a promising effect by preventing of iron sulfide scale deposition at threshold quantities. Specifically, the polymer did not prevent the...
