HydroxyEthyl Cellulose
Hydroxyethyl cellulose (HEC) is a series of non-ionic, water-soluble polymers. HEC exhibits thickening properties in processed and filled drilling muds. Within fracturing fluids, HEC serves to transport sand and gravel. These fluids can also be readily degraded by acids, enzymes, or oxidising agents to maximise hydrocarbon recovery. They are suitable for use in drilling and fracturing operations for natural gas, coalbed methane, and shale gas wells.
Polyanionic Cellulose
Low-viscosity polycationic cellulose exhibits excellent fluid loss control properties, whilst high-viscosity polycationic cellulose may serve as a viscosifier in water-based drilling fluids and low-density brines.
Carboxymethyl Starch
Carboxymethyl starch is a polymer compound produced through the chemical modification of starch. It exhibits excellent water solubility and thickening properties, making it commonly used as a fluid loss reducer in drilling fluids. Carboxymethyl starch effectively reduces fluid loss in drilling fluids, thereby minimizing formation damage and maintaining wellbore stability.
