Over the past decade the share of hard-to-recover reserves in the structure of oil reserves of Russian Federation has increased by 20%, wherein the production has increased by 15%. Development of conventional reservoirs often requires finding non-standard solutions due to the high level of uncertainty. Particularly in order to decrease petrophysical uncertainty level the hi-tech methods of well logging and the advanced data interpretation approaches are required. In Russian oil and gas industry to accomplish with the challenging petrophysical tasks mostly the foreign technologies have been used. Under the sanctions restrictions conditions the foreign technologies implementation causes certain difficulties associated with evaluation of petrophysical properties of complex reservoirs.
To acquire the technological independence in the area of hi-tech well logging methods Rosneft Oil Company starting from 2017 is actively involved in the process of domestic technologies development by providing sites and facilities for pilot field trials and by planning further equipment development concept. Company subsidiaries and design institutes have analyzed over 400 well logging appliances (design specifications and calibration, methodology and bench test data availability), and over 100 pilot field trials results of hi-tech well logging appliances performed on the Company sites. In the course of work the Rosneft experts have been actively communicating with the well logging appliances manufacturers for improving methodology and getting better results. Intensive collaboration between Rosneft Oil Company and the equipment manufacturers pushed on the domestic well survey service to the next level.
