Product Overview

Key Features

Polyplus Rd

POLY-PLUST RD: POLY-PLUS RD polymer is a readily dispersible product designed to provide cuttings encapsulation and shale stabilization. It is formulated for easy mixing with improved dispersion to eliminate "fish-eyes." This is beneficial when rapidly mixing either large quantities or high concentrations of polymer or where good mixing equipment is unavailable. POLY-PLUS RD also acts as a viscosifier, friction reducer, flocculant, and provides some fluid-loss control. POLY-PLUS RD is a specially treated, high-molecular-weight acrylic copolymer (PHPA). It can be used in mud systems ranging from low-solids to weighted muds, utilizing makeup waters from fresh to saltwater.

Applications

POLY-PLUS RD polymer mud systems. POLY-PLUS RD provides cuttings encapsulation and improved wellbore stability. Typical concentrations of POLY-PLUS RD are 0.25 to 1 lb/bbl (0.71 to 2.85 kg/m3). It is effective in salt muds such as Kcl or NaCl-enhanced fluids, although slightly higher concentrations of POLY-PLUS RD may be required. Clear-water fluids. POLY-PLUS RD may be used in clear-water, solidsfree, drilling fluids. POLY-PLUS RD enhances solids removal by flocculating the undesired solids and increasing viscosity. The polymer also provides cuttings encapsulation and improved wellbore stability. This system is frequently used in slimhole continuous-coring applications. Low-Solids, Non-Dispersed (LSND) muds. POLY-PLUS RD is well suited to LSND-type muds. In reducedbentonite muds, POLY-PLUS RD extends bentonite to increase viscosity, flocculates drill solids for more efficient removal, encapsulates cuttings and improves wellbore stability. Weighted muds. POLY-PLUS RD can be used in weighted muds for cuttings encapsulation, improved wellbore stability, secondary viscosity and to improve the filter-cake integrity. The effectiveness of the polymer is reduced as the concentration of organic anionic dispersants is increased. POLY-PLUS RD sweeps. Viscous POLY-PLUS RD sweeps are effective for periodic hole cleaning. Circulating a viscous sweep through the well clears accumulated cuttings and maintains a clean hole.
