Generalized Indicator

The generalized indicator of useful use, depending on the state of individual elements of oil-producing equipment, characterizes the ability of this equipment to perform its function during operation at optimal working time. The generalized indicator of the useful use of operational equipment can be described as the calculated sum of the indicator of the useful use of individual equipment elements. If, during operation, the oil-producing equipment retains its operability due to frequent replacement of its structural and non-structural elements, then such operational equipment is considered by users as outdated. Operating equipment can be divided into 6 categories according to the indicators of suitability. The article analyzes the state of useful use of equipment and, as a result, the total utility of equipment is calculated in accordance with the indicators of useful use by category, and graphs of changes in the state of useful use are constructed. Based on the study of the graphs of the useful use of equipment, it was proposed to conduct an analysis in the following areas: • Evaluation of the design and technological perfection of the equipment by users according to important new parameters. • Determination of equipment compliance with wear standards during operation. Keywords: structural element, wear theory, the usefulness of jam, categories, schedule of changes, reliability.

Environmental Mobilization

The state of Rio de Janeiro has become a hub for oil and gas production and infrastructure since Brazil entered the global oil market in the 2000s. Observers have anticipated increasing tensions between environmental activists and oil companies. These predictions have not been fulfilled, despite increasing evidence of environmental degradation caused by oil production. What could be hindering environmental mobilization in defense of the environment and affected populations and against the unrestrained expansion of oil infrastructure in the state? A longitudinal case study of environmental activism in defense of the Guanabara Bay ecosystem suggests that answers must consider the combined effects of democratization, political and regulatory decentralization, and neoliberal reforms on socioenvironmental activism—specifically, its weakening as civil society organizations confront increasing burdens of participation in policy making, deeply fragmented institutional and regulatory frameworks for environmental governance, and the expansion of opportunities to engage in collaborative arrangements with corporations. O Estado do Rio de Janeiro tornou-se o centro da infraestrutura e produção de gás e petróleo desde que o Brasil ingressou no mercado internacional de petróleo nos anos 2000. Analistas vêm antecipando crescente tensão entre ativistas ambientais e companhias petrolíferas. Contudo, essas previsões não se concretizaram, não obstante evidência da degradação ambiental que a produção de petróleo vem causando. O que poderia estar impedindo a mobilização em defesa do meio ambiente e populações afetadas, e contra a expansão desmedida da infraestrutura petrolífera no estado? Um estudo de caso longitudinal do ativismo ambiental em defesa dos ecossistemas da Baía de Guanabara sugere que as repostas a essa questão devem considerar os efeitos combinados da democratização, descentralização política e regulatória, e reformas neoliberais no ativismo socioambiental—especificamente, seu enfraquecimento à medida que organizações da sociedade civil confrontam crescentes custos de participação nas políticas públicas, fragmentação de arcabouços regulatórios e institucionais de governança ambiental, e a expansão de oportunidades de engajamento em arranjos colaborativos com corporações.

Oil And Gas Production

It is necessary to carry out work to analyze the harmful factors of accidents during the production, operation and transportation of raw materials in oil and gas fields and assess their compliance with the requirements of the standards of the Republic of Kazakhstan. The main goal of labor protection is to create safe working conditions for employees, as well as to prevent personnel from illnesses. In this regard, it is necessary to have a system of accounting, analysis and assessment of the state of labor protection, as well as management of labor protection. This article proposes ways to quickly assess the state of health and safety at work by calculating a number of occupational risk indicators based on information available in the modules for assessing occupational safety by industrial risk indicators. The efficiency of using the OSH management systems software proposed by the authors is based on a specific task from four main modules "Employees", "Events", "Equipment", "Ecology" and a number of submodules. In addition, this work uses matrix methods for assessing risks in the "Probability or Consequences of an Event" coordinate system, "Elmeri" system, "Fine Kinney" method, "Risks". Modern expert methods are compared and presented under the title "Five stages of assessment"

Trans, trans-muconic acid is generally considered a useful biomarker of exposure to benzene that occurs naturally in crude oil. Objective: To estimate exposure of benzene to workers in an oil and gas production company. Materials and Methods: Firstly, it was a descriptive, cross-sectional study which consisted of benzene atmospheric quantification in a sample individual measurements of a homogeneous exposure group of workers. Secondly, urinary assays of trans, trans-muconic acid have been performed at the end of the shift in the selected workers. Results: A total of 79 (47.88%) workers agreed to participate in the study. Seventeen atmospheric samples were usable and 79 urinary assays at the end of the shift were carried out. The average benzene concentration for all sites was 10 times lower than the regulatory average exposure value (1 ppm=3.25 mg/m3):average: 0.122pp, median: 0.053ppm and range: 0.019-1.448 ppm. All 79 urinary assays of trans, trans-muconic acid were below the biological exposure index (<500 µg/g creatinine) with an average of 37.34 µg/g creatinine, a median of 30 µg/g creatinine, and an extent from 10 to 150 µg/g creatinine. Conclusion: Airborne benzene concentrations were below company limits. The same was true for the urinary assays of trans, trans-muconic acid. Overall, therefore, exposure to benzene is low in this company. However, there is a need to maintain regular medical surveillance as the risk of exposure is ongoing.

The oil and gas production sector in Western Australia has grown dramatically in recent years and now represents the largest resource sector in the State economy. The industry has a very promising future but it faces a number of challenges if it is to achieve its full potential. Its production location in remote parts of the State confers both advantages and disadvantages. Chief among the disadvantages is the challenge of convincing the community and government of the benefits from the industry when many of those benefits are not apparent to the majority of the population. The emphasis in this paper is on economic impacts, social benefits and community attitudes.WA has produced about 820 million barrels of oil and 2000 million barrels of natural gas when gas is calculated in energy equivalent terms. Petroleum energy production has increased dramatically over the last 15 years and the State is now a substantial energy exporter. Petroleum sources provide the energy for over 85% of the final energy used in the State. Total industry investment over the last 18 years has been nearly $21,000 million for an average of $3.2 million each day. Direct employment by petroleum companies is around 2,500 people with flow-on employment in the services sector estimated at over 17,000 people. Petroleum companies have been major contributors to government revenue and to the development of remote regions in WA.

Parameter Values

The influence of two fundamentally different types of uncertainty on the value of oil field production are investigated here. First considered is the uncertainty caused by the fact that the expected value estimate is not one of the possible outcomes. To correctly allow for the risk attendant upon using the expected value as a measure of worth, even with statistically sharp parameters, one needs to incorporate the uncertainty of the expected value. Using a simple example we show how such incorporation allows for a clear determination of the relative risk of projects that may have the same expected value but very different risks. We also show how each project can be risked on its own using the expected value and variance. This uncertainty type is due to the possible pathways for different outcomes even when parameters categorizing the system are taken to be known. Second considered is the risk due to the fact that parameters in oil field estimates are just estimates and, as such, have their own intrinsic errors that influence the possible outcomes and make them less certain. This sort of risk depends upon the uncertainty of each parameter, and also the type of distribution the parameters are taken to be drawn from. In addition, not all uncertainties in parameter values are of equal importance in influencing an outcome probability. We show how can determine the relative importance for the parameters and so determine where to place effort to resolve the dominant contributions to risk if it is possible to do so. Considerations of whether to acquire new information, and also whether to undertake further studies under such an uncertain environment, are used as vehicles to address these concerns of risk due to uncertainty. In general, an oil filed development project has to contend with all the above types of risk and uncertainty. It is therefore of importance to have quantitative measures of risk so that one can compare and contrast the various effects, and so that corporate decision-makers can use the information in a rational manner as they seek to enhance corporate profit. This paper provides such methods and measures of assessing risk.
