ATREN SPACER S. Barrier spacer

Description

A composition based on polymer reagents and filler.

Application: in oil and gas industry, prevents mixing of drilling mud and cement slurries and serves for full mud removal in the bore hole annulus, that improves greatly cement bond.

Recommended consumption: 10—25 kg per 1 m³ of spacer solution.

Features

Gives the spacer the color different from the color of cement slurry and drilling mud, which provides efficient separation of processing fluids during cementation.
Increase of density of the spacer, prepared based on ATREN SPACER S, can be achieved by adding densifiers.
Compatible with all types of cement slurries and drilling mud and does not affect their rheological characteristics.
