Based on the analysis of data related to catastrophic losses when drilling horizontal wells due to their casing quality decrease, technical measures were prepared for using elastic systems for horizontal sections of M-fracturing. The article proposes technical solutions for the elimination of catastrophic absorptions based on fast-setting gypsum-cement mixtures, WTA-200 thixotropic additive, W-Block blocking composition and W-HimBlock (series 300) – a two-component blocking composition for eliminating absorption zones. These technical solutions will allow controlling over the thickening time, eliminating the possibility of the cement stone shrinkage, providing greater strength and a longer effect of absorption isolation in comparison with analogues.
