Drilling Specialties’ HE® 300 Polymer is one member of a family of synthetic, water-soluble polymers of varying composition and molecular weight developed for high temperature oilfield applications. This polymer is available as a powder and is an efficient thickener for a wide variety of fluid types including fresh water, seawater, brines and acids. It is designed to provide higher thermal stability than other water-soluble polymers
Applications
- As an acid viscosifier, for reducing fluid loss, extending acid spending time and improving stimulation results by increasing live acid penetration
- As a thickener for Slick Water Fracturing
- As a thickener for fresh water or brines in workover and completion operations
- In conformance control applications, HE® 300 Polymer provides superior high temperature stability. It is generally reserved for application where reservoir temperatures exceed 240 °F. It can be readily cross-linked with various organic systems, including phenol formaldehyde, resorcinol-formaldehyde, phenyl acetate-HMTA or hydroquinone-HMTA. Polymer loadings as high as 14 lb/BBL may be used in order to maximize gel rigidity in water shutoff treatments.
- As a high temperature fluid loss additive in silicate drilling fluids
Advantages
- Hydrates rapidly in most aqueous systems
- Resists thermally induced hydrolysis
- Maintains solubility at high temperatures
- Thickens brines of various compositions
- Improves carrying capacity of fluids
- Gel able with various organic cross-linkers
- High tolerance to changes in pH
