Drilling muds Testing 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 muds.
Laboratory specialists are developing formulations for water-based muds: biopolymer, without a solid phase with a high density, aerated muds with a reduced density, process fluids without a solid phase; and oil-based muds; invert emulsion solutions for various environmental requirements.
The laboratory searches, selects and, if necessary, synthesizes new reagents used as components of muds.
Drilling muds Testing Laboratory also promptly solves and eliminates problems that arise during the engineering support of drilling muds.
