Drill into better oil production

Useful in different forms of oil production, CELLOSIZE™ Hydroxyethyl Cellulose (HEC) is a family of nonionic, water-soluble polymers that can thicken, suspend, bind, stabilize, disperse, form films, emulsify, retain water and provide protective colloid action. These unique materials can be used to prepare solutions with a wide range of viscosities – including moderate viscosities with normal colloidal properties to maximum viscosities with minimal dissolved solids.

In workover and completion fluids, CELLOSIZE™ HEC is a viscosifier. It helps oil producers provide clear, low-solids fluids that help minimize damage to the formation. Fluids thickened with HEC are easily broken with acid, enzymes or oxidating agents to maximize the potential for hydrocarbon recovery.

In fracturing fluids, HEC materials act as carriers for proppants. These fluids also can be broken down easily with acid, enzymes or oxidating agents.

Using the low-solids concept, drilling fluids that are formulated with CELLOSIZE™ HEC offer increased penetration rates with good borehole stability. Property-inhibited fluids can be used in drilling medium-to-hard rock formations, as well as heaving or sloughing shales.

In cementing operations, HEC materials reduce hydraulic friction of the slurry and minimize water loss to the formation.
