Multicrete™ Thermal 50 Grout

Multicrete™ Thermal 50 Grout For Wellbore Application

In an environment where wellbore temperatures exceed 115°C, due to well depth, processes such as steam flooding, etc., there is a need for a special cement. Under these types of conditions, regular cement undergoes severe chemical structural changes causing a rapid breakdown of the cement integrity. Multicrete™ Thermal 50 Grout overcomes this degradation by blending higher content of silica (SiO2), which extends the Thermal ‘50’s stability to extreme temperatures up to +/-260°C.
