Low-molecular-weight liquid clay inhibitor
Achieve excellent cuttings encapsulation, limit cuttings dispersion, and stabilize shales.
Polyanionic-cellulose filtration-control additive
POLYPAC R polyanionic-cellulose filtration-control additive controls fluid loss in freshwater, seawater, potassium chloride, and salt muds. The polymer forms a thin, resilient, low-permeability filtercake that minimizes the potential for differential sticking and the invasion of filtrate and mud solids into permeable formations.
The additive resists bacterial attack, eliminating the need for biocides or preservatives. It is effective in low concentrations, with the normal treatment ranging from 0.25 to 1 lbm/bbl [0.71 to 2.85 kg/m3]. The additive also develops viscosity to a degree that is dependent on the solids concentration, salinity, and makeup water chemistry.
POLYPAC R additive attaches to and encapsulates exposed shales and drill cuttings. This protective polymer envelope inhibits the dispersion of shale cuttings and restricts fluid interactions with exposed shales.
