 Oil Drilling Grade HEC


Oil drilling is a process of oil exploration that uses mechanical equipment or manpower to enter the deep earth from the ground through drilling. It usually refers to boreholes and large diameter water supply Wells drilled for the exploration or development of oil, natural gas, liquid and gaseous minerals, etc.

Oil drilling grade HEC hydroxyethyl cellulose is a non-ionic soluble cellulose ether, soluble in hot and cold water, with thickening, suspension, adhesion, emulsification, film formation, water retention and protective colloid properties. Widely used in paint, cosmetics, oil drilling and other industries. The Oil drilling grade HEC is used as a thickener for a variety of muds in drilling, capping, cementing, and fracturing operations to achieve good fluidity and stability. Improved mud transportation during drilling stabilizes production by preventing large amounts of water from entering the reservoir.


  1. Hydroxy Ethyl Cellulose has excellent water- loss reducing performance, and API tests have shown this performance.
  2.  Hydroxy Ethyl Cellulose has good compatibility. The water-soluble HEC in solution can be mixed with the majority of the water-soluble resins, and can form a clear, homogeneous, viscous solution.
  3. Hydroxy Ethyl Cellulose has the temperature effect. As the solution temperature rises, its viscosity will decrease. And this process is reversible.
  4.  When Hydroxy Ethyl Cellulose is degraded by the enzyme catalysis, the viscosity of the solution will be affected and decreased.

Our HEC products can significantly improve various properties in cementing, drilling, completion, and fracturing. For more information, please contact us.
