HDCem

HDCem

Extra heavy cement systems engineered for cementing wells in conditions of abnormally high formation pressure (AHFP).

PHYSICAL PROPERTIES

Physical form: powder, gray to dark gray color
Water solubility: partial

PROPERTIES OF CEMENT STONE

Slurry density – from 2,10 g/cm3 to 2,25 g/cm3
Compression strength at 60°C after 24 hours is not less than 40 MPa
Thickening time – adjustable

PACKAGING AND STORAGE CONDITIONS

HDCem 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

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

ADVANTAGES

Increased early and final strength;
Sedimentation stability;
High hydrostatic pressure in the annulus space, which prevents gas, oil and water inflow

RESTRICTIONS CONCERNING THE USAGE

Operating temperature range: from 25°С to 110°С

 

USAGE

HDCem is made for cementing technical and flow strings in intervals with abnormally high formation pressure.

 

HDCem has a low cement stone permeability.

 

HDCem has higher sedimentation stability and lower fluid loss, which has a favorable effect on the cementing interval results.
