Dry polymer for filtration, shale stabilization
POLY‐PLUS DRY polymer is designed to provide cuttings encapsulation and shale stabilization. POLY‐PLUS DRY polymer also performs as a viscosifier, friction reducer, flocculant, and provides some fluid‐loss control. POLY‐PLUS DRY encapsulator is a high‐molecular‐weight PHPA copolymer. It can be used in mud systems ranging from low‐solids to weighted muds, utilizing makeup waters from fresh to saltwater.
POLY‐PLUS DRY polymer provides cuttings encapsulation and improved wellbore stability. POLY‐PLUS DRY additive can be used in clear‐water, solids‐free drilling fluids. POLY‐PLUS DRY polymer enhances solids removal by flocculating the undesired solids.
POLY‐PLUS DRY agent is well suited to LSND‐type muds. In reduced‐bentonite muds, it extends bentonite to increase viscosity, flocculates the drill solids for more efficient removal, encapsulates cuttings and improves wellbore stability. When drilling top hole, a liquid solution of POLY‐PLUS DRY polymer may be poured into the drill pipe during connections to help hole cleaning and maintaining a clean stabilizer and bit, improving ROP.
Advantages
- Excellent cuttings encapsulator to suppress cuttings dispersion
- Provides improved shale stabilization
- Powdered material with significantly lower toxicity than invert‐emulsion liquid PHPA polymers
- Improves the lubricity of most mud systems, particularly non‐dispersed muds
- Aids in preventing balling on the bit, stabilizers and Bottom‐Hole Assembly (BHA) by coating and lubricating solids
- Can be used to viscosify clear water and low‐solids drilling fluids
- Compatible with other polymers, such as POLYPAC, TACKLE, SP‐101, CMC, starch and DUO‐VIS
