When drilling deep oil and gas wells for the purpose of elimination of occurrences to increase the density of washing solution, white color barite is used as a weighting material. It is known that while opening many layers participating in stratigraphic profile, adding barite may cause explosions, fires and accidents. For elimination of analogical occurrences instead of increasing barite, the authors offer to apply another express method. This new method was applied in the well No 124 drilled to the 5958 m in Bulla-Deniz gas-condensate field and successfully prevent the accidents.
