Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer applied for enhanced oil recovery polymer flooding. After full hydration, entangled polymer networks increase injection fluid viscosity, balance mobility ratio between water phase and crude oil. The product mitigates water channeling, improves sweep efficiency and releases trapped residual oil in porous formations. Featuring stable rheological performance and moderate salt tolerance, PEO serves as an effi

Product Detail

Product Overview

Polyethylene Oxide PEO CAS 25322-68-3 is a professional water-soluble polymer additive developed for oilfield enhanced oil recovery polymer flooding. Heterogeneous reservoirs easily cause fluid channeling, resulting in low sweep efficiency of conventional polymer flooding. This PEO product effectively regulates the rheological property of displacement fluid, expands swept area, and maximizes crude oil extraction rate. It can be compounded with common flooding polymers to reduce development cost and raise oilfield ultimate recovery factor.

Key Features

CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
Increase aqueous viscosity and optimize mobility ratio of polymer flooding fluid
Suppress water channeling and improve sweep efficiency in heterogeneous formations
Effectively displace residual crude oil to boost oil recovery rate
Nonionic polymer, excellent compatibility with polyacrylamide and auxiliary agents
Stable performance in low and medium salinity formation water
Rapid hydration, convenient for continuous liquid preparation at injection stations
Multiple molecular weight grades to match different reservoir geological conditions

Main Applications

Auxiliary polymer additive for onshore oilfield polymer flooding EOR
Rheology modifier for displacement fluid of medium & low salinity reservoirs
Functional additive to improve sweep efficiency of conventional water flooding
Experimental raw material for research of novel composite oil displacement formulas

Usage Guidance

Slowly disperse PEO powder into injection water under gentle stirring to avoid agglomeration and fish-eye particles. Prepare pre-hydrated mother liquor before mixing with main flooding polymer. Core flooding laboratory tests are recommended to confirm optimal mixing ratio and dosage. Avoid long-time high-shear circulation, which will break polymer molecular chains and weaken performance.
