Drilling Fluids

Hydroxyethyl Cellulose(HEC) is used as thickener and fluid loss reducer in water-based drilling fluids and completion fluids, and has an obvious thickening effect in saltwater drilling fluids. It can also be used as a fluid loss control agent for oil well cement. Can be cross-linked with polyvalent metal ions to form gels.

HEC has tackifying properties in drilling fluids processing and filling slurries. It helps provide good low solids mud with minimal damage to the wellbore. Slurry thickened with HEC is easily degraded to hydrocarbons by acids, enzymes or oxidants and maximizes oil recovery.

In the fractured mud, HEC can play the role of carrying mud and sand. These fluids can also be easily degraded by the above acids, enzymes or oxidants.

Ideal low solids drilling fluid can be formulated with HEC, which provides greater permeability and better drilling stability. Its fluid-retaining properties can be used in drilling hard rock formations as well as in slump or slump shale formations.

In the operation of adding cement, HEC reduces the frictional resistance of the pore pressure cement slurry, thereby minimizing the damage to the structure caused by the loss of water..
