Polymers for enhanced oil recovery: fundamentals

Abstract As the energy demand is escalating tremendously and crude oil being the primary energy source for at least the next two decades, the production of crude oil should be enhanced to meet the global energy needs. This can be achieved by either exploration of new oil fields for crude oil extraction or employing enhanced oil recovery (EOR) technology to recover the residual oil from ...

Polyacrylamide-based Polymers for Enhanced Oil Recovery

The polymers tested were modified HPAM-based co-polymers functionalized with 2-acrylamido-2-methylpropane sulfonate (AMPS) monomers. The sulfonated polyacrylamide co-polymers FLOCOMB C7035, AN132 VHM, SUPERPUSHER SAV55, and THERMOASSOCIATIF were aged at 80?C for 90 days with and without an antioxidant. The evaluations were conducted in ...

enhancement of oil recovery by surfactant-polymer synergy

Enhancement of oil recovery by surfactant-polymer synergy

In too-thin oil layers or too-deep oil layers, thermal recovery faces serious heat loss, excessive carbon dioxide (CO 2) emissions, and high heating costs. 15 The problem of poor fluidity control caused by gas flooding leads to low displacement efficiency. 16 Therefore, chemical flooding is widely used to enhance oil recovery and prolong oilfiel...

review of surfactant-assisted chemical enhanced oil recovery

Review of surfactant-assisted chemical enhanced oil recovery

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%¨C40% of original oil in place from these reserves, the need for enhanced oil recovery (EOR) techniques for incremental oil recovery has become imperative. With the challenges ...

Application of Polymers for Chemical Enhanced Oil Recovery: A

The remaining oil-in-place is the target of enhanced oil recovery (EOR). Hence, EOR methods are used for recovering bypassed and residual oil in the reservoir [2,3]. The devised EOR methods are majorly classified into thermal and nonthermal EOR. Thermal EOR is unsuitable for reservoirs with huge depths, thin pay zones, or underlying aquifers.

Hybrid Application of Nanoparticles and Polymer in Enhanced

Polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) are two of the most functional polymers for enhanced oil recovery processes that help to mobilize the oil phase by increasing water viscosity, wettability alteration, and interfacial tension reduction [57,58,59]. The following features would be essential in providing efficient ...
