- DSGA® Polymer

DSGA^® Polymer

Drilling Specialties Gelled Acid (DSGA^®) Polymer is a superior gelling agent for acids used in stimulating production from oil and gas wells. It was developed specifically to provide exceptionally stable viscosity in hydrochloric acid. Since its introduction in 1983, DSGA^® Polymer has been successfully used in acidizing treatments throughout the world in a variety of formations, acid concentrations, high-temperature environments and divalent ion conditions.

The complete spectrum of hydrochloric acid concentrations, ranging from 1% to 28%, may be viscosified with DSGA^® Polymer for matrix or fracture acidizing treatments in limestone, dolomite or other calcareous formations. DSGA^® Polymer offers the key property of maintaining a stable viscosity, thereby assisting in controlling fluid leak-off to the formation and retarding the acid reaction rate with the acid-soluble formation.

DSGA Polymer is Proven in the Field

For over ten years DSGA^® Polymer has successfully increased the production of oil and gas wells the world over. Many operators have seen the production improvement sustained for long periods: even one and two years after acidizing. Wells from 80 to 340°F (27 to 171°C) BHST have been stimulated by hydrochloric acid gelled with DSGA^®Polymer.
