To assess development characteristics of Bazhenov formation the authors applied the new technology of hydraulic fracturing in wells, located in the South-Eastern part of Western Siberia. The new technology is based on use of composition, represented by 99.5% of fresh water and the other ingredients represented proppant decreased of friction, acid, clay stabilizer, etc. such a technology referred to as Slick Water. The peculiarity of the technology Slick Water is an injection of a large volume of water, reaching up to 900-1200 m3 at one stage of hydraulic fracturing. For experimental works we selected vertically drilled wells which discovered Bazhenov formation. In these wells according to the interpretation of well logging data we selected the most fragile intervals for the perforation before fracturing. Test results showed that Bazhenov formation reached the necessary maturity, formed liquid hydrocarbons, and can be developed. In the result of well No. 2 (area B) tests 6.7 m3 of oil and 402.5 m3 of water were produced, average watercut amounted to 98.3%, for well No. 1 (area A) 18 m3, 189.3 m3, 91.3% respectively. Wells performans demonstrated Bazhenov formation potential and the prospect of hydrocarbon production. We have to admit that at present in Russia there is no methodology to carry out the forecast distribution of zones of fracture in Bazhenov formation, for scheduling of drilling new wells, for which it is necessary to carry out a preliminary study of the distribution zones of fracture. Based on the results of the test we can conclude that in case of intermittent operation oil production rate will not exceed 2-3 tons if zones of abnormally high reservoir pressure are not drilled in.
