He specializes in the issues of construction and operation of directional and horizontal wells. Main works are dedicated to solution of the problems of improvement of efficiency of use of modern technologies for improvement of well oil extraction drilling in process technical-and-economic indicators. A plan of technical and process actions on construction and operation of designer wells developed with contributions from S. I. Grachev is realized at 20 horizontal and more than 100 directional designer wells, including 6 wells with a bottom hole deviation up to 2,500 m and 3 multibranch horizontal wells at fields of the Western Siberia. The results of the researches are stated in 11 scientific technical reports and 22 projects on Van-Eganskoye, Vat-Eganskoye, Kalchinskoye, Koshilskoye, Malochernogorskoye, Samotlorskoye, Yuzhnoye and Chernogorskoye fields.
