«BURINTEKH», Ltd Drilling Fluids Testing Laboratory represents the scientific and research base with full cycle of researches on making and implementation of new perspective developments in the sphere of drilling fluids.

Specialists formulate water-based solutions: biopolymer without solids with high density, aerated drilling fluids with decreased density, process liquids without solids; and oil-based solutions: invert-emulsion drilling mud for different ecological requirements.

Laboratory provides searching, selection, and if needed, synthesizing of new reagents, used as components of drilling fluids.

Also laboratory allows operatively solve and correct problems, arising during engineering maintenance of fluids.
