Dow Industrial Specialty Polymers in Oil and Gas Exploration Applications

CELLOSIZE™ HEC polymers have long set the standard among oilfield viscosifiers for drilling, completion, and workover fluids. And Dow continues to maintain a high level of commitment to the oilfield industry, with dedicated inventories for oilfield applications and service to you through a network of oilfield service organizations.

CELLOSIZE HEC is a viscosifier in workover and completion fluids. It helps provide clear, low-solid fluids that impart minimum formation damage. Fluids thickened with CELLOSIZE HEC are easily broken with acid, enzymes, or oxidating agents to maximize the potential for hydrocarbon recovery.

In fracturing fluids, CELLOSIZE HEC acts as a carrier for proppants. These fluids can also be easily broken by the above techniques.

Drilling fluids formulated with CELLOSIZE HEC, using the low-solids concept, 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, CELLOSIZE HEC reduces hydraulic friction of the slurry and minimizes water loss to the formation.
