Viscosifiers
Product Description
Hydroxyethyl cellulose is a high-purity chemical cotton or pulp and the alkali-catalyzed reaction of ethylene oxide is made. HEC processing and filling in the mud with increasing viscosity. Thickened slurry with easy acids, enzymes or oxidizing degradation of hydrocarbons and maximizing the recovery of oil. These fluids can easily be more acid, enzyme or oxidant degradation.
Application/Function
HEC can be formulated with the ideal low-solid drilling fluid, which provides greater penetration and better drilling stability. The rejection characteristics of the fluid can be used in hard rock drilling in the layer structure, the same applies to Bengtan or slippery layer of drilling slump page
Cement operations in the filling, HEC reduces pore pressure slurry friction, so that the loss of water damage to the structure reduced to a minimum
Advantages
Helps provide a good low-solid mud, and can reduce the hole minimum damage
Thickeneds slurry with easy acids, enzymes or oxidizing degradation of hydrocarbons and maximizing the recovery of oil
Ruptures in the mud
Plays the role of sediment carried

Environmental Information
Add HEC in concentrations of 0.5 to 4 lb/bbl (1.43 to 11.4 kg/m3). For maximum effectiveness, slowly add HEC through the hopper while mixing into a neutral-pH fluid for 30 min. This ensures complete hydration and maximum viscosity development.
Shipping
Transportation of commodity name is not restricted by either international or CHINA regulatory agencies
Safe Handling Recommendations
Utilize normal precautions for employee protection when handling chemical products. Use of standard PPE is recommended for employee comfort and safety. See Material Safety Data Sheet (MSDS) prior to use.
