Cellulose ethers in Oilfield

Hydroxyethyl cellulose (HEC) is a water-soluble polymer used in drilling and fracturing fluids for thickening, stabilization, and fluid-loss control. It enhances viscosity for cuttings suspension, improves wellbore stability, and ensures efficient proppant transport. With thermal stability (up to 150°C), salt compatibility, and eco-friendliness, HEC boosts efficiency in high-pressure reservoirs while minimizing formation damage.
