In the oil industry decline oil is mainly due to the structure of reservoir rocks, most of which are of hard, energy-depleted and highly flooded deposits, high heterogeneity which leads to uneven extraction of oil.Mechanical methods of influence effective in hard rock when creating additional cracks in the bottomhole formation zone allows you to attach to the filtration process of the new remote reservoir. One of the most popular and promising methods of intensification of the displacement, increased filtration-capacitive characteristics of face working space zone wells is hydraulic fracturing. Therefore, as the practice of hydraulic fracturing is more profitable than building a new well economically and in terms of development. This article describes the features of interval hydraulic fracturing in horizontal wells.
