Special compositions and technologies for elimination of lost circulation in wells at Republic Saha (Yakutia) fields and license areas are developed. Results of research and experimental-field works are given. The technology of solar-cement- bentonitic mixtures delivery in the disastrous lost circulation zone is considered.
