Polyethylene Oxide MW 10,000,000 (PEO 10M, CAS 25322-68-3) is linear ultra-high molecular weight water-soluble polyether polymer. Applied in enhanced oil recovery systems, hydrated polymer chains form stable viscous networks. It adjusts water-oil mobility ratio, reduces channeling, enlarges swept volume and promotes residual crude oil displacement. Featuring excellent thickening property and low residue characteristics, it serves as high-performance functional polymer for reservoir flooding and

Product Detail

Product Overview

Polyethylene Oxide MW 10,000,000 (CAS 25322-68-3) is ultra-high molecular weight PEO developed for tertiary oil recovery. Conventional polymer cannot achieve ideal mobility control; ultra-high molecular weight alternatives easily suffer shear degradation and poor dissolution. This 10M grade balances thickening efficiency, shear resistance and on-site operability.

After dissolution and injection into underground formations, the viscous flooding fluid evenly pushes crude oil towards production wells. It mitigates preferential water flow along high-permeability zones and effectively lifts oil recovery factor.

Key Features

Molecular Weight: 10,000,000, CAS 25322-68-3, white free-flowing fine powder
Outstanding thickening efficiency with ultra-low dosage
Optimize mobility ratio, restrain water channeling and improve sweep efficiency
Moderate temperature adaptability for medium-temperature oil reservoirs
Low residue after degradation, minimizing permanent formation damage
Nonionic structure, compatible with various oilfield auxiliary additives
Stable viscosity under common underground reservoir salinity conditions

Main Applications

Mobility control thickener for EOR water flooding displacement fluid
Profile control and water shutoff auxiliary polymer for oil reservoirs
Viscosifying additive for low-damage oilfield treatment fluids
Functional raw material for laboratory tertiary recovery simulation research

Usage Guidance

Slowly disperse PEO powder into gently stirred water to prevent agglomeration and fish-eye particles. Prepare mother solution before injection. Conduct indoor viscosity testing, static adsorption and core flooding evaluation to confirm optimal concentration. Avoid long-time high-shear stirring to prevent molecular chain rupture.
