The rapid development of drilling and completion of horizontal wells (HW), as well as the need for successful selective well interventions requires the growth of informativeness of field geophysics to meet the needs of production. The greatest difficulty in conducting geophysical logging in the area of development control is caused by the non-uniform flow pattern in the HW and the lack of effective methods for delivering equipment to the bottom hole of the HW. Currently, the standard short-term field geophysical logging technology in horizontal wells has been successfully applied to the assets of Gazprom Neft. The technology has been modified for different types of wells both in terms of the research tool, and in terms of delivery technologies and feed-in inducing methods. A further increase in the effectiveness of the geophysical logging in HW, including multilateral HW and multi-fractured HW (MFHW), is associated with the transition from the usual methods of standard one-time logging to stationary distributed or point-distri buted monitoring of the inflow / intake profile of horizontal wells. The main stationary monitoring systems, such as fiber optic systems for temperature (DTS) and acoustics (DAS) and point-distributed indicator studies, have already been tested in the first wells of the Company. In order to be able to use these systems on a wide range of wells, the methodological and technological component of research by these systems is currently being developed. The article presents recommendations of Gazprom Neft experts to increase the informativeness of research of HW and MFHW and minimize the risk of an accident during the downhole operations, as well as conclusions regarding the informativeness and effectiveness of new methods for remote monitoring of low permeability formation in wells with complex completion based on the results of testing and implementation of stationary monitoring systems in the Company.
