Abstract
Background. Priobsky license area is one of the largest in terms of assets production of Oil Company Rosneft», as well as the leader in the number of initiated pilot industrial tests and pilot works (PW). It was within the framework of the PW that the first clusters were drilled by horizontal wells and carrying out multistage hydraulic fracturing of the reservoir (HW with MHF), which resulted in the decision to introduce them massively throughout the Priobsky license area. Like any new technology at the implementation phase, the technology of HW with MHF in its realization stage also requires optimization solutions, and it may take years to evaluate the effectiveness of these decisions. Aims and Objectives. There considered issues related to: • creation of an integrated system for monitoring HW with MHF for determining the effectiveness of their operation; • increasing the effectiveness of the HW with MHF. Rezults. There proposed the approaches to create the system of monitoring and analysis of the effectiveness of HW with MHF at the implementation stage, as well as a primary assessment of problem wells with a view to further increasing their efficiency through the implementation of measures. The optimal variants of the formation of a reservoir pressure maintenance system (PMS) and the timing of mining in injection wells for clusters with different geological conditions are determined. The calculated terms of transfers are already used for an operative assessment of the appropriateness of transfers of directional wells in the PMS at a number of fields. Optimal quantities of MHF stages and proppant loading on HW are determined depending on different geological conditions. The actual implementation of the first three wells with an increased number of stages of MHF confirmed the success of this direction.
