    Study of polyacrylamide-surfactant system on the water–oil. Nowadays, due to the remarkable oil reduction in oil fields, enhanced oil recovery (EOR) techniques have been considered by a large number of scientists and company. Situ oil extraction is normally done by these techniques with high efficiency. In

  • biodegradation of polyacrylamide and its derivatives in ...

    A considerable fraction of fossil oil remains in the reservoirs after drilling and primary production. Partially hydrolysed polyacrylamide and its derivatives have been used for enhanced oil recovery of the residual oil. Polyacrylamide is added to water to increase its viscosity and thereby its sweep efficiency. Get Price

    2014-1-13 · Enhanced oil recovery (EOR) involves injecting a fluid into an oil reservoir that increases oil recovery over that which would be achieved from just pressure maintenance by water or gas injection. For lighter oils, these processes include miscible gas injection [ 6 , 7 ], water alternating gas (WAG) injection [ 8 ], polymer flooding [ 9 ], flow ...

    2017-11-4 · A significant fraction of the conventional oil reserves globally is in carbonate formations which contain a substantial amount of residual oil. Since primary and secondary recovery methods fail to yield above 20%–40% of original oil in place from these reserves, the need for enhanced oil recovery (EOR) techniques for incremental oil recovery has become imperative.
