Abstract The energy transition to renewable energy and hydrogen as an energy carrier, along with low-carbon footprint production targets in the oil and gas industry act as a catalytic for exploring the role of hydrogen in oil and gas production. For upstream and midstream operations, potential opportunities for using hydrogen as an energy carrier are being developed both in hydrogen generation (X-to-hydrogen) as well as in hydrogen consumption (hydrogen-to-X), but not without series of technical and economical challenges. This paper presents potential use cases in upstream and midstream facilities for hydrogen generation and consumption, be it both from hydrocarbon processing resultant in what is called "blue hydrogen" or from integration with renewable energy to form what is called "green hydrogen". It also explains process integration requirements with diagrams for full-cycle green hydrogen use from generation to consumption and its interaction with renewable energy technologies to achieve low to zero-carbon emission power supply systems. Different hydrogen generation and conversion technologies are reviewed as part of the modeling process. Green hydrogen feasibility is assessed in terms of operational efficiency and cost constraints. Hybrid hydrogen and renewable energy power supply systems are simulated and presented according to the intended applications of use in oil and gas facilities. This paper provides a feasibility analysis and hydrogen technology integration potential with renewable energy for applications in oil and gas remote facilities power supply. It also shows emerging hydrogen technologies potential for use in upstream and midstream applications.

Traction Power

Steel pipelines for transporting oil and gas can run along the routes of AC main railways. As a result of the electromagnetic influence of traction networks on pipes having insulating coatings, voltages can be induced that are hazardous to personnel who operate the pipeline. The report addressed the issues of modeling the electromagnetic effects of a promising traction network of 94 kV on a steel pipeline with a diameter of 250 mm laid on the surface of the earth. Computer simulation showed that at a distance of 100 meters from the railway line to the pipeline, the maximum induced voltage reaches 100 V, which is more than one and a half times the permissible value. This factor must be taken into account when designing prospective traction power supply systems in the areas of their convergence with main pipelines

Autonomous power sources are widely used in systems for power supply to industrial facilities, especially in the oil and gas industries that have affordable energy carriers. These sources can be used both separately and in combination with centralized power supply, as primary, backup, or emergency sources. Their operation is characterized by the features that affect power supply reliability and must be taken into account when deciding on their use in the stages of designing new power supply systems or modernizing existing ones. The use of methodology and software for calculating the reliability of systems with autonomous power sources in the stage of pre-project research can contribute to more informed decision-making. In this stage, there is no need and opportunity to consider all reliability issues in detail. Here, express methods are enough to take into account the main features of the systems functioning with autonomous or mixed power sources and to compare the proposed system options within a single methodological framework. Based on this, a methodology was developed to calculate the reliability of power supply systems with autonomous and mixed power sources. The proposed methodology employs semi-Markov random processes (Markov chains) and can be used in comparative reliability analysis of power supply options with autonomous and mixed power sources. It was implemented in software and is accompanied by an example of reliability calculation for power supply to a stationary platform for maintaining reservoir pressure in an offshore oil field.

An adequate description of reliability in decision-making models for managing the restoration of its properties is a complex scientific task. Quite a lot of attention has been paid to the correct solution of this problem in various fields of technology. The article proposes and implements a probabilistic approach to calculating the circuit reliability of the power supply system using an assessment of the actual state of its main elements. The assessment of the state of the equipment of the power supply system is carried out using an integral indicator of the technical condition. This creates the basis for applying a risk-based approach to the management of maintenance and repairs to assess the consequences and feasibility of repair and restoration work of power equipment while minimizing possible damage from power outages to consumers. The article presents two methods for calculating reliability, focused on both recoverable and non-recoverable elements of the power supply system. In addition, a decision-making model for managing repairs of power equipment in power supply systems is proposed. A separate case is considered when the power supply system provides electricity to a mono-consumer, which is typical for oil and gas production. Based on the analysis of scenarios for the implementation of the risk-based approach, the influence of various degrees of severity of the consequences of failure on the assessment of decisions made is studied. The developed models and methods are illustrated by computational examples from the practice of operating electrical equipment in power supply systems with a monoconsumer
