WP SPACER Spacer
A one-sack system WP SPACER is powder material that can be mixed with fresh water and weighted with barite to produce a variable density cement spacer. WP SPACER remains viscous and supports solids up to 300°F (149°C), separates the cement slurry from displacing fluid or completion fluid, prevents contamination, cleans the well bore (casing and well bore walls) and allows for a better bond to the casing and well bore. WP SPACER performs in water and oil based systems.
NERSPACE 200 Preflush liquid, surfactant
NERSPACE 200 is effective, environmentally friendly, water-soluble preflush composition used to thin and disperse drilling-fluid particles, and separate drilling fluids and cementing slurries. NERSPACE 200 is designed for use with either water-based drilling fluids or NERSPACE 200 OBM version for oil-based drilling fluids. Typical application is in the range of 0.50 to 0.15% by volume of water and then run as a spacer volume of 500 to 2000 gallons (2000 to 8000 L). For winter time is recommended to use powder washing agent NERSPACE 100.
