| Summary: | Title screen The main uncertainties in the field development with the use of multiple-fractured horizontal wells (MFHW) in waterflooding are the inflow/injection profile along the horizontal wellbore, the number of working hydraulic fracturing ports, the dynamics of the productivity factor, the presence of the self-induced fracturing effect. All these factors affect the sweep efficiency and oil recovery factor. To remove uncertainties and increase the efficiency of waterflooding, a systematic approach to the control and management of the MFHW is required. Implementation of this approach is an important direction of technological development of Gazprom Neft PJSC. The creation of a system for monitoring and managing the MFHW is based on the search, sampling, analysis of efficiency and selection of control technologies (geophysical studies for removal of uncertainties) and management technologies (well interventions for improvement of operational efficiency of MFHW). One of the most promising technologies for monitoring the MFHW is long-term monitoring of downhole parameters (temperature and noise) with fiber-optic systems (FOS). Gazprom Neft PJSC has a positive expirience in this area, which includes the use of the FOS of various configurations, design and interpretation of the results of this type of research. Therefore, the main issue of using FOS in MFHW is the delivery of optical fiber to the horizontal part of the well with the possibility of further carrying out the well interventions without dismantling the FOS. The paper describes the results of testing a unique method of delivery of fiber-optic cable in the MFHW using coiled tubing and hydraulic anchor at the field in the Orenburg region.
