Some conflicts support the project goals and improve their whole performance. On the other hand, some can be an obstacle to the performance. As a result, this would lead to the tension between the company and contractor which prevents the project from progressing smoothly and within the budget and deadline. This research works on the complexity and conflict phenomena and tries to understand complexity, sources of conflicts between the two parties (company and contractor) and how they are managed in a mega gas producing project in Iran (one of the phases of South Pars Gas Field Development situated in Asaluyeh) as a case study. The research uses Grounded Theory as its methodology. In this regard, data were collected entirely through interviews from twelve experts, observations and documents reviews in the year 2018. The collected data were then analyzed utilizing a set of coding (open, axial and selective) procedures and the Leximancer software. The initial findings show that unpredicted issues (especially sanctions) increasing time and cost of the project have been among the three main drivers of the conflicts which had resulted in the project complexity. The project scope clarification, intra-organizational structure, and liquidity were also among the sources of conflicts.

Prospects for the Use of Autonomous Underwater Vehicles (AUV) to Solve the Problems of the Mineral Resources Complex (MRC) of the Russian Federation, 2024

One of the acute industry problems of the Mineral Resource Complexes (MRC) is the insufficient geological study of the territory of Russia and its continental shelf. This paper demonstrates a review of the world’s experience with using AUV to solve such tasks. Also, it considers the possibility of using AUV for exploration of the MRC and escorting their extraction in the water areas of the Russian Federation by using methods of system analysis and a mathematical model. The results show that in Russia there is a shortage of specialists in the development and creation of both AUV and AUV, as well as control systems. However, it should be considered that bringing Russian research to an advanced level of development in the fields of ocean research and the exploration of mineral resources requires a significant increase in funding. Besides, the development and establishment of AUV in Russia for the resolution of MRC problems is a pressing issue that must be addressed.

A SUSTAINABLE DEVELOPMENT GOALS-BASED MATHEMATICAL MODEL FOR SELECTING OIL AND GAS INVESTMENT PROJECTS UNDER UNCERTAINTY AND LIMITED RESOURCES, 2023

Based on the economic dimension of sustainability, the profit from the implementation of petrochemical projects is maximized, and based on the environmental dimension, the amount of greenhouse gas emissions, energy consumption, and produced waste is minimized. According to the social dimension, the number of job opportunities, the number of people covered by insurance, the job satisfaction of employees, the project's impact on the regional economy, and the number of lost workdays is examined. The uncertainty of the strategic and operational parameters of the model has also been considered, and to deal with the uncertainty, fuzzy possibility programming (FPP) is used. The model is solved in GAMS optimization software with a two-stage approach based on fuzzy programming and the best-worst group decision-making method (BWM). Numerical results confirm the effectiveness of the proposed model and show that SDG will lead to a significant improvement in economic, environmental, and social dimensions without significantly reducing the profits of the selected oil and gas projects.

However, before hydrogen can be widely used, a new pipeline network must be built to reliably supply industrial users. An alternative way to rather expensive investments in new infrastructure could be to use the existing pipeline network to add pure hydrogen to natural gas and further transport the gas mixture in an industrially safe way. The new solution necessities will be examined for compression, transportation, and fire hazard accidents, which have not been scrutinized by other scholars. This study presents the results of a comprehensive analysis of the methane–hydrogen mixture compression process and a mathematical description of the main pipeline operation during gas mixture transportation, considering industrial fire safety issues. By examining a case study involving a main gas pipeline and its associated mathematical model for hydrogen transportation, it becomes feasible to assess the potential hazards associated with various leakage areas and the subsequent occurrence of fires. The findings of this investigation demonstrate that the spontaneous combustion of hydrogen due to leakage from a natural gas pipeline is directly influenced by the proportion of hydrogen present in the gas mixture. If the hydrogen percentage reaches a balanced ratio of 50–50%, it is plausible that the equipment at the compressor station could be subject to detrimental consequences, potentially leading to accidents and fires. Furthermore, the obtained results from modeling in ANSYS Fluent software propose two practical scenarios, which demonstrate that despite the limited research conducted on the safety aspects and the occurrence of fires during the operation of hydrogen gas pipelines, industrial and fire safety necessitate the inclusion of hydrogen transport infrastructure as a pivotal element within the broader framework of hydrogen infrastructure development.

The oil terminal in St. Petersburg, which is a part of Russia's Multimodal Transportation System (MTS) in the NorthWest , was chosen as the study subject. A simulation model has been created in AnyLogic software that uses Agent-Based and Discrete Event Methods (ABM and DEM) A computational experiment was conducted based on the developed full-factor plan using a simulation model. The process of the terminal operation was optimized; as a result, to increase the absolute throughput capacity, it was proposed to increase the unloading speed, which will decrease the tankers' servicing time and thereby increase the throughput capacity practically twice. People have come up with ideas for how to put the technical solution into action. The main idea is to update the pipeline system and fittings so that they can pump oil products more quickly.

Depending on the refining process and the CO2 capture method, costs ofCO2emissions can be avoided from 30 to 40 Euros per tons ofCO2. Advanced low-temperature CO2 capture technologies for upgrading oxyfuel reformers may not provide significant long-term and short-term benefits compared to conventional technologies. For this reason, an analysis was conducted to estimate the CO2 reduction potential for the oil and gas in-dustry using short- and long-term ST/MT technologies, which was about 0.5–1 Gt/yr. The low cost of CO2 reduction comes from the good integration of CO2 capture into the oil production process. The results show that advanced gasoline fraction recovery with integrated CO2 capture can reduce the cost of petroleum product production and reduce CO2 emissions and partial CO2 capture can have comparative advantages in some cases.

One of these pollutants is volatile organic compounds (VOC), which contribute to the formation of tropospheric ozone. Emissions of hydrocarbon formation in the form of volatile organic compounds occur in four stages of the fuel and energy industry sector: 1) production; 2) processing; 3) transportation; and 4) storage. The oil and gas industry ranks among the top polluting industries in terms of VOC emissions. Research of the negative impact of VOCs, as well as CO 2 emissions from the consequences of the extraction, processing, transport, and storage of oil and gas on the ecosystem of the planet and the population, has begun to be studied by science recently. Typically, these studies were conducted using laboratory and field analyses, as well as using data on anthropogenic emissions in the development of regulatory documents and requirements governing the control of VOC and CO 2 emissions in the oil and gas industry.
