BT-SA-121A Spacer

BT-SA-121A Spacer

Product Description:                                                                   

Gray powder, BT-SA-121A is a viscous spacer designed to displace mud at laminar flow technique. It can be used for both freshwater and saltwater mud systems. It can be used up to 300^oF. The criteria are to keep density and viscosity of BT-SA-121A system between those of drilling mud system and cement slurry by adjusting the concentration of BT-SA-121A. It can be mixed with freshwater, seawater, and salt water depend on application requirement, general dosage 10-40kg/m³. Slurry density can be adjusted up to 2.6g/cm³.

Primary Function:                                                                   

Acting as a buffer between cement slurry and drilling fluids with specific density and rheological properties.
