LightCem Ultra

LightCem Ultra

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 PROPERTIES

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.

CHEMICAL SPECIFICATION

LightCem Ultra is a multi-component mixture of materials, predominantly of inorganic origin

ADVANTAGES

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

USAGE

LightCem Ultra is used for cementing technical and flow strings, and liners in intervals with a low hydraulic fracturing factor

 

LightCem Ultra has higher early and final strength of cement stone

 

LightCem Ultra has high sedimentation stability and reduced water loss and low permeability, which has a favorable effect on the cementing interval results
