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.

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

Abstract Digital oilfield applications have been implemented in numerous operating companies to streamline processes and automate workflows to optimize oil and gas production in real-time. These applications are mostly deployed using traditional on-premises systems; where maintenance, accessibility and scalability serves as a major bottleneck for an efficient outcome. In addition to this challenge, the sector still faces limitations in data integration from disparate data sources, liberation of consolidated data for consumption and cross domain workflow orchestration of that data. The dimensional change brought by digital transformation strategies has paved a path for the Cloud- based solutions, which have recently gained momentum in the oil and gas industry pertaining to their wider accessibility, simpler customization, greater system stability and scalability to support larger amount of data in a performant way. To address the challenges mentioned earlier, we have embarked on a journey with Production Data Foundation which brings together production and equipment data from across an organization. In this paper, we will highlight how Production Data Foundation, hosted on the cloud, provides the underlying infrastructure, services, interfaces required to support and unify production data ingestion, workflow orchestration, and through the alignment of the common domain and digital concepts, improve collaboration between people in distinct roles, such as production engineers, reservoir engineers, drilling engineers, deployment engineers, software developers, data scientists, architects, and subject matter experts (SME) working with production operations products and solutions.

We talk about “the energy transition” as if it were some type of unified, global event. Instead, numerous approaches to energy transitions are taking place in parallel, with all of the “players” moving at different paces, in different directions, and with different guiding philosophies. Which companies are best positioned to survive and thrive, and why? This article takes a look at what several top energy research and business intelligence firms are saying. What a Difference a Year Makes Prior to 2020—in fact, as recently as the 2014 bust that followed the shale boom—the oil and gas industry weathered downturns by “tightening their belts” and “doing more with less” in the form of cutting capital expenditures and costs, tapping credit lines, and improving operational efficiency. Adopting advanced digitalization and cognitive technologies as integral parts of the supply chain from 2015 to 2019 led to significant performance improvements as companies dealt with “shale shock.” Then, in 2020, a strange thing happened. Just as disruptive technologies like electric vehicles and solar photovoltaic and new batteries were gaining traction and decarbonization and environmental, social, and governance (ESG) issues were rising to the top of global social and policy agendas, COVID-19 left companies with almost nothing to squeeze from their supply chains, and budget cuts had a direct impact on operational performance and short-term operational plans. To stabilize their returns, many oil and gas companies revised and reshaped their portfolios and business strategies around decarbonization and alternative energy sources. The result: The investment in efforts toward effecting energy transition surpassed $500 billion for the first time in early 2021 ($501.3 billion, a 9% increase over 2019, according to BloombergNEF) despite the economic disruption caused by COVID-19. According to Wood Mackenzie, carbon emissions and carbon intensity are now key metrics in any project’s final investment decision. And, Rystad Energy said that greenhouse-gas emissions are declining faster than what is outlined in many conventional models regarded as aggressive scenarios. In Rystad’s model, electrification levels will reach 80% by 2050. A Look at the Playing Field: Energy Transition Pillars In a February 2021 webinar, Rystad discussed what leading exploration and production (E&P) companies are doing to keep up with the energy transition and stay investable in the rapidly changing market environment. The consulting firm researched the top 25 E&P companies based on their oil and gas production in 2020 and analyzed how they approach various market criteria in “three pillars of energy transition in the E&P sector” that the firm regards as key distinguishers and important indicators of potential success (Fig. 1). The research excludes national oil companies (NOCs) except for those with international activity (INOCs). Rystad says these 25 companies are responsible for almost 40% of global hydrocarbon production and the same share of global E&P investments and believes the trends within this peer group are representative on a global scale.

Long Run

One of the biggest challenges in oil and gas production projects is dealing with the various types of corrosion to which certain parts of field equipment are exposed. Selecting the right corrosion inhibitor for the specific environment is extremely important. Choosing inhibitors for a particular location can be a difficult task because there are many factors to be considered. Understanding the corrosion problems that can arise is important in the oil and gas industry, and knowledge of which inhibitors to use to deal with general and localized corrosion will save time and money in the long run. This article presents the results of studies of various brands of domestic and foreign corrosion inhibitors for use in the Uzen field: physical and chemical characteristics (density, viscosity, freezing temperature, mass fraction of active substance, compatibility with field waters, amine number), efficiency of corrosion inhibitors in laboratory conditions and on a bench simulating field reservoir conditions, taking into account pressure, temperature, fluid flow rate, as well as aggressive components - hydrogen sulfide and carbon dioxide. In addition, studies of corrosion inhibitors' effect on the process of preparation of production are also given. The works were carried out in the center of scientific and laboratory research of KMG Engineering branch " KazNIPImunaygas" LLP.

This chapter examines the deep Texas-California divide over energy and environmental policies. The modern Texas economy was built on energy, and the state remains the nation’s leading producer. The state’s development of fracking has revolutionized the oil and gas industry and has helped the nation break its dependence on foreign oil. Texas has also increased its production of renewable energy, but believes the global economy will rely for the foreseeable future on fossil fuels and resists restrictions on these resources. California, by contrast, has become a global leader in the fight against climate change. It has aggressively regulated carbon emissions and mandated a massive switch to renewable energy sources. California is the only state that can impose emissions regulations more strict than federal standards. As power has shifted in Washington, California has alternated between translating its environmental policies into federal law and defending its policies from federal challenge.

Extreme Salinity

Environmental context The treatment of extremely saline, high-strength wastewaters while producing electricity represents a great opportunity to mitigate environmental effects and recover resources associated with wastes from shale oil and gas production. This paper demonstrates that extreme halophilic microbes can produce electricity at salinity up to 3- to 7-fold higher than sea water. Abstract Many industries generate hypersaline wastewaters with high organic strength, which represent a major challenge for pollution control and resource recovery. This study assesses the potential for microbial fuel cells (MFCs) to treat such wastewaters and generate electricity under extreme salinity. A power density of up to 71mWm–2 (318mWm–3) with a Coulombic efficiency of 42% was obtained with 100gL–1 NaCl, and the capability of MFCs to generate electricity in the presence of up to 250gL–1 NaCl was demonstrated for the first time. Pyrosequencing analysis of the microbial community colonising the anode showed the predominance of a single genus, Halanaerobium (85.7%), which has been found in late flowback fluids and is widely distributed in shale formations and oil reservoirs. Overall, this work encourages further research to assess the feasibility of MFCs to treat hypersaline wastewaters generated by the oil and gas industry.
