It is a cement system that allows cementing of well sections with a high probability of cross-flows. Such intervals are often prone to the formation of channels in the cement stone, which subsequently leads to a shutdown of the mining process and repair and isolation squeeze.
Physical form: powder, gray to dark gray color
Water solubility: partial
PROPERTIES OF CEMENT STONE
Slurry density – from 1.8 g/cm3 to 2 g/cm3
Compression strength at 60°C after 24 hours is not less than 19 MPa

PACKAGING AND STORAGE CONDITIONS
ExtendCem G is packed in soft containers weighing up to 1 ton, equipped with a triple polyethylene liner.
The product should be stored in a dry place on pallets, away from moisture, open flames and heating appliances. After the bag has been opened, it must be carefully closed to avoid damage to the product.
The shelf life of the product is not less than 12 months.
ExtendCem G is a multi-component mixture of materials, predominantly of inorganic origin
Improving the adhesion properties of the cement slurry, improving the bond quality of the casing / formation contact
Creates a back pressure inside the system while in a borehole annulus and prevents fluid invasion into the cement slurry column during the transition period.
Expanding effect – maximizes annular space filling
RESTRICTIONS CONCERNING THE USAGE
