ExtendCem G

ExtendCem G

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 PROPERTIES

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
Thickening time at 60°C – adjustable

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.

CHEMICAL SPECIFICATION

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

ADVANTAGES

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

Operating temperature range: from 15°С to 110°С

USAGE

ExtendCem for cementing technical and flow strings in intervals with a high probability of fluid migration

 

ExtendCem fills the annular space as much as possible during the well cementing process, which has a positive effect on both the quality of isolation and well logging results. Has compressive properties

 

ExtendCem is characterized by high sedimentation stability, reduced water loss and low permeability, which has a favorable effect on the cementing interval results
