The efficiency analysis of applying hydraulic fracturing of formation at AB_1-2 facility of Potochnoye field

Evaluation of the effectiveness of sealing the grid of wells at an oil facility

“…However, to determine the technological indicators for the development of such deposits and production planning, a more reliable assessment of reserves is necessary. When analyzing the development of many deposits confined to various carbonate strata in the Ural-Volga region, new patterns were identified [1][2]7].…”

“…The composition of oil reserves gradually changes during the development of deposits; at later stages, for example, the percentage of areas with low productivity increases, where the extraction of products is associated with significant difficulties. [1] In this situation, production efficiency decreases; The process of operating facilities is thus subject to adjustment, which is carried out by implementing complex geological and technical measures at both production and injection wells. Thus, the effectiveness of using these measures directly depends on the selection of optimal methods for increasing oil production, taking into account the characteristics of the deposit being developed.…”

“…All of the above confirms the economic significance of the development in the Republic of Tatarstan of innovative methods (geological-technical, technological and organizational) to increase the efficiency of developing oil fields with a complex structure at the current stage of development of the national fuel and energy complex. [1] In addition, it should be noted that the introduction of hard-to-recover oil reserves into active development and increasing the efficiency of already actively developed objects can be difficult due to the insufficient number of impact measures suitable for use in complex-structured deposits and at the same time proven in practice. In addition, another significant problem is that issues related to methods of opening formations during drilling and operating wells, as well as determining the optimal grid density, have not yet been resolved; Thus, the operation of complex objects requires solving them and selecting the most effective operating mode.…”

Substantiation of geological exploration and modeling of oil deposits for multistage fracturing in a horizontal well

“…In order to determine profitability, it is necessary to assess the amount of cumulative oil production over 7-20 years. To assess the effectiveness of the measures taken, it is necessary to consider a large number of geological and field factors [3,6].…”

“…To date, maintained rate of oil production and optimal performance, as well as increased oil recovery factor, are crucial for fields at the late exploitation stage [1][2][3]. The oil production area can be expanded by commisionning horizontal wells.…”
