It is an ultra-lightweight cement system that allows the creation of cement stone with increased early and final strength. The LightCem Ultra system helps to reduce the risk of hydraulic fracturing due to low hydraulic fracturing ratio, to perform cementing in one stage avoiding the use of a stage collar in the casing set
Physical form: powder, gray to dark gray color
Water solubility: partial
PROPERTIES OF CEMENT STONE
Slurry density – from 1,25 g/cm3 to 1,4 g/cm3
Compression strength at 46°C after 24 hours is not less than 3 MPa
Thickening time at 60°C – adjustable
PACKAGING AND STORAGE CONDITIONS
LightCem Ultra 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.
LightCem Ultra is a multi-component mixture of materials, predominantly of inorganic origin
No risk of early opening of the hydraulic cement stage collar during flushing
No risk of coupling leakage, leading to the ingress of cement slurry into the tube space
No risk of problems while lowering caused by the increased outer diameter of the cement stage collar
RESTRICTIONS CONCERNING THE USAGE
Operating temperature range: from 15°С to 110°С
