Backfill materials
Preview
Magnesia backfill material “BIT-Cem-M”
Designed for cementing casing strings that cover deposits of easily soluble salts and other rocks.
Lightweight backfill material “BIT-Cem-L”
In order to simplify the process and reduce the cost of well casing it is important to use lightweight materials for well cementing in one stage.
Expanding backfill material “BIT-Cem-RTM”
Designed for cementing operation well pay zones, injection intervals (in injection wells) in order to improve the quality of formation isolation.
Impact-resistant reinforced backfill material “BIT-Cem-Arm”
The main feature is that the cement stone of such a slurry has an impact strength much more than ordinary cement.
Gypsum-cement backfill material “BIT-Cem-Gips”
It is intended for casing wells in permafrost conditions, lost circulation control.
