A mix of sized particles of various organic origins. It is designed to prevent circulation losses in fractured zones and for the effective development of anti-filtration barrier in the permeable rocks. Depending on the mix preparation technique and the nature of permeable rocks, the filler provides development of leak-tight anti-filtration plug or low-slump plug.
Range of applications
The reagent is a mix of plugging agents to prevent drilling mud absorption in the rocks of various origins. Extra fine and fine fractions can be used to reduce drilling mud filtration in highly porous sandstones. Mixes of this kind of grinding can be run in through the drill stem assembly and large and middle bit nozzles. It is recommended
