Polyethylene Oxide CAS 25322-68-3 Viscosifier for Water Based Drilling Mud
Polyethylene Oxide (PEO, CAS 25322-68-3) is linear nonionic water-soluble polyether polymer developed for water-based drilling mud systems. After hydration, entangled polymer networks raise apparent viscosity of drilling fluid, enhance carrying capacity for drill cuttings and stabilize wellbore. Meanwhile, it assists in reducing fluid filtration loss into formations. With stable rheological properties and excellent compatibility, PEO acts as efficient viscosifying additive for water-based drilli
Product Overview
Polyethylene Oxide CAS 25322-68-3 is multifunctional viscosifying polymer for water-based drilling mud. Ordinary inorganic viscosifiers often lack sufficient cuttings suspension ability. This PEO polymer effectively adjusts drilling fluid rheology, maintains stable viscosity under construction conditions, improves hole cleaning efficiency and reduces risks of pipe sticking. It can be matched with bentonite and other treating agents to build reliable water-based drilling fluid systems.
Key Features
- CAS Number: 25322-68-3, Appearance: White free-flowing fine powder
- Efficient viscosifying capacity to increase apparent viscosity of water-based drilling fluid
- Improve drill cuttings suspension and hole cleaning performance
- Assist in controlling fluid loss and protect shallow formations
- Nonionic polymer, good compatibility with bentonite, inhibitor and lubricants
- Fast hydration in fresh water and low salinity formation water
- Low dosage required, easy continuous mixing at mud pits
- Multiple molecular weight options to adjust target mud rheology
Main Applications
- Viscosifier & rheology modifier for conventional water-based drilling mud
- Cuttings suspension additive for onshore shallow and medium-depth well drilling
- Functional polymer for environmental friendly low-solid water-based drilling fluid
- Auxiliary additive for workover and completion water-based fluid systems
Usage Guidance
Slowly disperse PEO powder under mild stirring to avoid agglomeration and fish-eye particles. Prepare pre-hydrated mother liquor before adding into mud tank. Perform lab rheology test to confirm optimal dosage. Avoid long-time high shear agitation which degrades polymer chains and reduces viscosity building effect.
