Researches of backfill materials, reagents for properties control

Drilling muds development Laboratory “BURINTEKH”, Ltd is a research base with a full cycle of research on the creation and implementation of new promising developments in the field of backfill materials, displacement fluids and lost circulation materials.

Laboratory specialists are engaged in the development of backfill material formulations to improve the quality of formation isolation in the interval of productive horizons and prevent the occurrence of cross-flows during casing lining the hole, the development of LCM in various geological conditions, as well as the solution of various related tasks.

To date the following main types of materials have been developed and used:

• Expandable backfill material designed for cementing productive intervals;
• Impact-resistant reinforced backfill material with increased resistance to shock and cyclic loads;
• Lightweight backfill material designed to reduce well casing costs, for well cementing in one stage, without stage cementing collar;
• Magnesian backfill material for cementing salt-saturated formations;
• Backfill materials for remedial cementing;
• Compositions for lost circulation control;
• Buffer fluids.

Reagents development Laboratory analyzes the current situation with the casing string, identifies the reasons for the poor quality of lining and determines the directions for the improvement. Laboratory performs search and selection of components of backfill materials for the development of formulations of materials, taking into account the characteristics of the field. The equipment of the laboratory allows determining all the basic parameters of the cement slurry and cement stone for normal and moderate temperature conditions

Reagents development Laboratory also promptly solves and eliminates problems that arise during the engineering support of casing string cementing and installation of cement bridges.
