    (Видавнича група «Наукові перспективи», 2022) Krasniuk, Maksym; Краснюк, Максим Тарасович; Kulynych, Yurii; Кулинич, Юрій Михайлович; Hrashchenko, Iryna; Гращенко, Ірина Семенівна; Honcharenko, Svitlana; Гончаренко, Світлана Миколаївна; Krasniuk, Svitlana; Краснюк, Світлана Олександрівна
    The following factors were studied and taken into account in the process of economic and mathematical modeling of an oil and gas company as a complete complex specific system: a significant inertia of a management object; multi-level management structure; irregularity of a management system of an oil and gas company; a need to decompose the system along the weakest lines of communication "vertically" and "horizontally" and build economic and mathematical models of smaller dimensions for each selected element. Determining an algorithm that connects economic and mathematical models of the technological, tactical and strategic management levels of an oil and gas company is a very difficult task. Economic and mathematical modeling of the technological level of an oil and gas company should contribute to management of functioning of main technological objects of the oil and gas production: to ensure optimal modes of operation under the selected optimality criteria; must take into account the parallel-sequential flow of operations and is the most studied level of an economic and mathematical management of an oil and gas company. Economic and mathematical modeling of the tactical level of management of an oil and gas company as optimality criteria involves maximizing profit and minimizing integral costs; and can be formalized in the form of economic and mathematical models of the following interconnected blocks: geological and industrial, production, transport and economic. Economic and mathematical modeling of the strategic level of an oil and gas company should reflect the strategic goal of the development of a company and the industry. The basis for building an economic and mathematical model of an oil and gas production company is the choice of optimality criterion, which characterizes the entire activity of the company for a certain period of time, in particular, the criterion of maximum profit. However, for making cost-effective decisions in the management of complex systems (an oil and gas production company) in the conditions of a sharp change in market prices, this criterion is impractical. Since economic efficiency does not necessarily mean high profitability, that is, in the conditions of constant changes in the world economy, the most stable position in a long term is the system characterized by maximum efficiency, and not profitability, which also depends on random factors (constant price fluctuations on the energy carrier is the norm of the modern world economy). Objectively, it turned out that the most developed issues of economic and mathematical modeling of the strategic level of management are for processing industries, not extractive ones. Therefore, when building economic and mathematical models of a strategic planning level of an oil and gas production company, researchers face difficulties caused by the specifics of the industry, in particular: product stocks for a given field are always limited; a production cost of 1 ton of conventional hydrocarbon fuel from one field increases significantly during its life cycle; it is difficult to determine the degree of detailing of the models. The use of economic and mathematical modeling in managerial processes on the part of the information system of an oil and gas production company faces sociological, political and other limitations, which an experienced manager should take into account when making a final decision. The main task of the oil and gas production complex is to ensure production and a growing renewal of hydrocarbon reserves. The problem of improving quality of a balance of explored reserves should be solved by an oil and gas company by opening new fields, features of which largely determine the specifics of planning, organization of a process and a material and technical base of work, determination of the industrial value of explored reserves, etc. The economic indicators of effectiveness of work on development of discovered reserves should include the amount of capital investments, operating costs, cost of production, profit, profitability, payback period, etc. To determine the total profit of an oil and gas company from the development of reserves, the system of criteria and economic indicators of a subsoil is used. Which is used at all stages of prospecting and development of reserves for: - substantiating economic feasibility of carrying out work on the search and exploration of oil and gas deposits; - establishment of a valuation of recoverable hydrocarbon reserves; - ranking of individual prospective plots into groups according to economic criteria and a sequence of their development; - forecasting of oil and gas prices, taking into account the level of forecasted cumulative specific costs for preparation and development of reserves and expected profit. Making managerial decisions regarding investment projects of an oil and gas company requires determining the value of underground reserves (resources) and is characterized by a set of indicators that generally reflect the comparison of expected (obtained) results with necessary costs for participants in a geological exploration process. In the article, the concept of economic and mathematical modeling of an oil and gas company as a complete complex specific system was further developed. The main factors and limitations are taken into account, the specifics of economicmathematical modeling of oil and gas company management at the technological, tactical and strategic levels are investigated. У процесі економіко-математичного моделювання нафтогазового підприємства як цілісної комплексної специфічної системи досліджувалися та враховувалися такі фактори: значна інертність об’єкта управління; багаторівнева структура управління; невідлагодженість системи управління нафтогазовою компанією; необхідність декомпозиції системи по найслабших лініях зв'язку «по вертикалі» і «горизонталі» і побудови економіко-математичних моделей меншої розмірності для кожного обраного елемента. Визначення алгоритму, що зв’язує економіко-математичні моделі технологічного, тактичного та стратегічного рівнів управління нафтогазовою компанією, є дуже складним завданням. Економіко-математичне моделювання технологічного рівня нафтогазового підприємства має сприяти управлінню функціонуванням основних технологічних об’єктів нафтогазовидобутку: забезпечити оптимальні режими роботи за обраними критеріями оптимальності; має враховувати паралельно-послідовний перебіг операцій і є найбільш вивченим рівнем економіко-математичного управління нафтогазовою компанією. Економіко-математичне моделювання тактичного рівня управління нафтогазовим підприємством як критерій оптимальності передбачає максимізацію прибутку та мінімізацію інтегральних витрат; і можуть бути формалізовані у вигляді економіко-математичних моделей наступних взаємопов’язаних блоків: геолого-промислового, виробничого, транспортно-економічного. Економіко-математичне моделювання стратегічного рівня нафтогазової компанії має відображати стратегічну мету розвитку компанії та галузі. Основою побудови економіко-математичної моделі нафтогазовидобувного підприємства є вибір критерію оптимальності, який характеризує всю діяльність підприємства за певний період часу, зокрема, критерію максимального прибутку. Однак для прийняття економічно ефективних рішень в управлінні складними системами (нафтогазовидобувною компанією) в умовах різкої зміни ринкових цін цей критерій є недоцільним. Оскільки економічна ефективність не обов’язково означає високу рентабельність, тобто в умовах постійних змін у світовій економіці найбільш стабільну позицію в довгостроковій перспективі має система, яка характеризується максимальною ефективністю, а не прибутковістю, яка також залежить від випадкових факторів. (постійні коливання цін на енергоносій є нормою сучасної світової економіки). Об’єктивно виявилося, що найбільш розробленими є питання економіко-математичного моделювання стратегічного рівня управління для переробних галузей, а не видобувних. Тому при побудові економіко-математичних моделей рівня стратегічного планування нафтогазовидобувної компанії дослідники стикаються з труднощами, зумовленими специфікою галузі, зокрема: запаси продукції для даного родовища завжди обмежені; собівартість видобутку 1 тонни умовного вуглеводневого палива з одного родовища значно зростає протягом життєвого циклу; складно визначити ступінь деталізації моделей. Використання економіко-математичного моделювання в управлінських процесах з боку інформаційної системи нафтогазовидобувної компанії стикається з соціологічними, політичними та іншими обмеженнями, які досвідчений менеджер повинен враховувати при прийнятті остаточного рішення. Основним завданням нафтогазовидобувного комплексу є забезпечення видобутку та зростаюче відновлення запасів вуглеводнів. Проблема підвищення якості балансу розвіданих запасів нафтогазової компанії повинна вирішуватися шляхом відкриття нових родовищ, особливості яких значною мірою визначають специфіку планування, організації процесу та матеріально-технічної бази роботи, визначення промислове значення розвіданих запасів і т. д. Економічні показники ефективності робіт з розробки виявлених запасів повинні включати обсяг капітальних вкладень, експлуатаційні витрати, собівартість продукції, прибуток, рентабельність, термін окупності і т. д. Для визначення загального прибутку нафтогазової компанії від розробки запасів використовується система критеріїв та економічних показників надр. Який використовується на всіх етапах пошуку та розробки запасів для: - обґрунтування економічної доцільності проведення робіт з пошуку та розвідки родовищ нафти і газу; - встановлення оцінки видобувних запасів вуглеводнів; - ранжування окремих перспективних ділянок на групи за економічними ознаками та послідовність їх освоєння; - прогнозування цін на нафту і газ з урахуванням рівня прогнозованих сукупних питомих витрат на підготовку і розробку запасів та очікуваного прибутку. У статті отримано подальший розвиток концепції економіко-математичного моделювання нафтогазового підприємства як цілісної комплексної специфічної системи. Враховано основні фактори та обмеження, досліджено специфіку економіко-математичного моделювання управління нафтогазовим підприємством на технологічному, тактичному та стратегічному рівнях.

    Hybrid application of decision trees, fuzzy logic and production rules for supporting investment decision making (on the example of an oil and gas producing company)
    (ACCESS Press, 2022) Krasniuk, Maksym; Краснюк, Максим Тарасович; Hrashchenko, Iryna; Honcharenko, Svitlana; Krasniuk, Svitlana
    During the last years, in most countries of Eastern Europe (and Ukraine in particular), even a simple reproduction of onshore hydrocarbon reserves was not ensured. Achieving the possible level of self-sufficiency in fuel and energy resources is a fundamental task of national economies, without which the successful implementation of economic, scientific, technical and social programs aimed at ensuring state independence and stability in Europe is impossible. However, the onshore oil and gas industry of the countries of Eastern Europe with significant volumes of unexplored oil and gas resources, with the cost of oil and gas several times lower than world prices, the presence of a significant number of oil and gas industries, drilling and geophysical enterprises, oil refineries, and an extensive network of oil and gas pipelines , highly qualified production teams allows, with their effective use, not only to stabilize, but also to significantly increase the production of oil, gas and condensate in the future. An important reason for the drop in oil and gas production volumes is insufficient management efficiency of the cycle of parallel business processes of the oil and gas company: field exploration, their arrangement and development, production and sale of oil and gas. The solution is the application of effective economic-mathematical modeling at the strategic level of management and the use of knowledge-oriented decision-making support tools as an integral component of the complex information system of an oil and gas company. Objectives: Therefore, the issues of: development of a complex system of economic and mathematical support for making fair and timely investment decisions at the macro level of an oil and gas production company, effective application of knowledge-oriented hybrid methods and technologies are becoming particularly relevant. Methods/Approach: The paper uses a mathematical apparatus of the method of fuzzy logic, decision trees, data mining, knowledge-oriented decision support, theory of investment management and expertise in the field of management of oil&gas exploration and production local and international investment projects. Results: first proposed the decision tree diagram of the effective investment management process of a oil and gas company in the search for hydrocarbons in modern economic conditions is proposed; received further development of the principles of hybrid application of intelligent technologies and knowledge-oriented basis and the problem of handling uncertainty while supporting investment decisions of an oil and gas company; first proposed two related prognostic models are proposed: the seismic impact model and a drilling impact model; first proposed two algorithms/models based on economic-mathematical modeling with elements of fuzzy knowledge to support decision-making of the tender&controlling committee of oil&gas production company. Conclusions: Based on the foregoing, it can be concluded that it is efficient to use developed by authors hybrid, knowledge-oriented investment decision support for oil and gas production projects in Ukraine and other countries of Eastern Europe.

    Innovative management information system in post-crisis economic conditions on emerging markets (on the example of the oil and gas industry)
    (Mezinárodní Ekonomický Institut s.r.o., 2023) Krasniuk, Maksym; Краснюк, Максим Тарасович; Kulynych, Yurii; Hrashchenko, Iryna; Krasniuk, Svitlana; Honcharenko, Svitlana; Chernysh, Tetiana
    The formation and development of the oil and gas industry in any region (country) of the world is primarily related to the volume of forecast hydrocarbon resources, the state of explored hydrocarbon reserves and is determined by a number of technological, economic, organizational, political and other factors. Ukraine is no exception – one of the oldest oil and gas producing countries in the world. Before starting the analysis, we need to define some terms that we will use in this subsection: - proven hydrocarbon reserves are known volumes of hydrocarbons that can be profitably extracted using existing technology; - unexplored traditional resources – oil and gas resources that are explored by oil and gas companies with developed technologies and that can be profitably extracted/developed using the existing traditional practice of hydrocarbon development; - unconventional resources – oil and gas resources that exist outside well-defined traps; - resources obtained due to the growth of deposits – resourcesthat are expected to be added to the explored reserves of the deposit due to: physical expansion of the boundaries of the deposit, development of new horizons, more careful calculation and evaluation of deposit reserves based on mining experience and changes in the relationship between price and costs; application of new technologies and methods of search, development, extraction of hydrocarbons and processing of relevant information. To a large extent, the listed factors depend on innovations, which are difficult to predict. In addition, these factors are complex and interrelated, and therefore difficult to analyze individually. Thus, the assessment of the possible future increase in reserves should be based on the empirical projection of past patterns.

    (NGO European Scientific Platform, 2024-03-15) Krasniuk, Maksym; Краснюк, Максим Тарасович; Hrashchenko, Iryna; Kulynych, Yurii; Sydorenko, Tetiana; Krasnyuk, Svitlana
    The changes that have taken place in the Ukrainian economy in recent years due to the consistent impact of global macroeconomic, epidemiological and military factors of the current deep crisis - actualized for enterprises and corporations a complex adaptive reorganization of their analytical subsystem of their management [1, 2]. In addition, in order to be consistently effective in today's global business environment (liberalization of markets, their globalization, increased competition, decreasing consumer loyalty, constant variation in oil and gas prices, etc.), oil and gas companies must have an innovative data and knowledge environment that allows seamless and effective joint leveraging knowledge inside the corporation and across the value chain [3]. The application of knowledge-based decision support systems as an important tool of innovative management policy enables effective and sustainable management of a complex of integrated processes of an oil and gas production company (mitigating the impact of crisis factors) [4]. The scientific and practical results presented in the article regarding the methodology and design of innovative analytical subsystem of the corporation management information systems should be taken into account when reengineering corporate information systems not only in the oil and gas industry in Ukraine [5-6]. Moreover, the obtained results are relevant and applicable not only for local companies, but also for international corporations on emerging markets in the context of global and regional macroeconomic and edipemical crisis phenomena.

    Technological and tactical subsystems of the intelligent management information system (on the example of an oil and gas corporation)
    (NGO European Scientific Platform, 2024-03-15) Krasniuk, Maksym; Краснюк, Максим Тарасович; Kulynych, Yurii; Hrashchenko, Iryna; Krasnyuk, Svitlana; Honcharenko, Svitlana; Denysenko, Vitalina
    Providing Ukraine with its own oil and natural gas is one of the main tasks of the national economy. The possibility of development of the oil and gas industry is primarily determined by the volume of explored and mined resources. Since the existing explored reserves will not ensure the growth of oil and gas production, it is necessary to increase the amount of investments in the exploration and development of new deposits and hydrocarbon deposits with the aim of increasing their reserves and further growth of production, which requires the adoption of management decisions, which are characterized by increased technological and economic risk, uncertainty. Taking into account the main reasons for the decline in oil and gas production in Ukraine, the specifics of the industry and the requirements for information systems in the oil and gas industry, it can be argued that the use of intelligent technologies not only at the strategic, but also at the tactical and technological levels of management - is one of the keys to success in creating/reengineering, implementation and effective use of management decision support systems. The scientific and practical results presented in the article regarding the innovative configurations of architecture and design, proposed intellectual methodology for tactical and technological subsystems of the corporation management information systems. The above-proposed solutions - should be taken into account when reengineering corporate information systems not only in the oil and gas industry in Ukraine [1-3]. Moreover, the obtained results are relevant and applicable not only for local companies, but also for international corporations on emerging markets in the context of global and regional macroeconomic and military crisis phenomena.
