Since 2019, in the Subsurface Use Monitoring System, the process of calculating MET rate has been automated and the process of generating Novaoil Petro- format regulated report has being implemented on the basis of State Register of Reserves data. The report is stored and visualized in the System. Automation helps to reduce labor resources and increase the accuracy of the calculations needed.

Since 2020, as part of the development of Upstream information systems, the following electronic modules continue to be operated:

– of the OIS Tekhnolog, where various functions of monitoring of well measuring parameters, coming directly from the field telemetry system are implemented;

– of the OIS Field Equipment, where real-time records of tubing and sucker rods with the functions of calculating quarterly and semi-annual availability, and reconciliation with accounting are provided;

– of the automated system of planning and analysis of well intervention efficiency, which allows to improve the timeliness of technological calculations, introduce electronic interaction of specialists, automate some functions for the formation of immediate reporting and analysis of the effectiveness of well intervention.

The Company adheres to the principles of responsibility in elaborating civil solutions using artificial intelligence (AI) and in 2023 joined the AI Code of Ethics (hereinafter referred to as the Code), as well as undertakes to follow the provisions, rules and principles set up in the Code.

Since 2023, the Company has been implementing a number of digital solutions with AI elements. At the moment, the Company is testing, at the stage of pilot tests, a third party “Virtual Flow Meter” model, which allows, based on the correlation of many parameters, to determine the dynamics of the current well flow rate and identify criteria for the maximum flow rate.

Competencies in the development of hard-to-recover reserves (HTR reserves) and well stimulation technology

In 2019-2023, efficiency in operations with HTR reserves was ensured by the Integrated System of Field Development Optimization introduced in the Company. The main components of the system are:

• • Unified digital information and analysis system for improving the efficiency of development;
  • Modern approaches and software for Proxy and 3D geological and hydrodynamic modelling, taking into account geomechanics and nonlinear filtration in the reservoir;
  • A system for operational streamlining of development in production drilling zones, taking into account existent geology, geomechanics and actual production data for the construction of new wells;
  • Integrated multivariate techno-economic modelling of field development strategy;
  • Factor analysis of base production and well intervention, Integral analysis of the current state of development, well intervention planning.
