Aiming at improving the eco-efficiency of the oil and gas industry, the author suggests the use of life cycle assessment methodology to study oil and gas production facilities as illustrated by the oil-and-gas well. The peculiarities of the research object are the complexity of technological processes and equipment and the multifactorial effects on the environment. The basic principles of the methodology of life cycle assessment have been analyzed. The author specifies the boundaries of the investigated system which includes all stages of the life cycle of an oil-and-gas well: site preparation, rigging up, well drilling, testing, rigging down, assembly of production equipment, well development, well operation, closing-in, well decommissioning. The inventory of single processes of the production system was carried out. It gives a possibility to identify incoming and outgoing elementary flows at each stage. The histograms to determine the power and diversity of incoming and outgoing flows have been built. The approximate duration of each stage is given. This duration makes it possible to estimate the exposure time of single processes and to identify the potential effects on the environment. The most resource-consuming stages have been established. They are drilling, rigging up, rigging down, and decommissioning of wells. Based on to the results of analytical studies of the outgoing flows, the stages with the greatest diversity and flow capacity are established. The potential risk of hazardous environmental emergencies during the life cycle of the investigated facility is determined. The obtained data give a possibility to start researching those processes and / or equipment with which there is intense movement of flows with significant effects on the environment, as well as to develop innovative technical solutions and improve technological processes to reduce the harmful effects on the environment. The conducted research determines a number of advantages of the life cycle assessment methodology for improving the indicators of eco-efficiency. The advantages include a systematic study of the effects of the activities, the multivariate analysis, the identification of the potential for the reduction of impacts and constant improvement throughout the life cycle.

The research purposes are analyzing food availability, food procurement diversity, and analyzing target formulation, procurement necessity, and food production in Malang in 2016 - 2019. The analysis used is Food Balance Sheet (FBS) and Food Desirable Dietary Pattern (FDDP). The analysis result shows that the food availability in Malang is dominated by plant food source with 81,75 % of percentages. The total of energy availability value is 2.227 kcal/kap/day and protein 63,77 gram/kap/day. The quality of food availability measured with FDDP is 89,33 which shows that food diversity is not maximal yet. Overall, the food availability energy in Malang has not fulfilled Recommended Dietary Energy (RDE) standard and the protein is more than Recommended Dietary Protein (RDP), in which RDE ideal is 2.400 kcal/kap/day and RDP is 63 gram/kap/day. RDE and RDP of ideal food availability can be reached by increasing and decreasing food commodity group gradually from 2016 to 2019. The food commodity groups that need to be increased are such as; cereals, pulse nut and oil seeds, animal food, vegetable, and fruit. While the commodity groups that need to be decreased are such as starchy food, nut, oil and fat, animal food, and sugar.

Modern tendencies of development of world and domestic oil and gas processing involve deep processing of heavy oil and condensate residues for the production of motor fuels and other petroleum products and minimizing the production of energy boiler fuel. Modern technological processes of deep recycling of oil and gas condensate residues are conventionally divided into four large groups: direct processes consisting of one main standard process; combined processes consisting of two or more interconnected generally used refining processes including possible pre-refining of raw materials; processes using slurry reactors and reactors with a suspension catalyst bed for nanoheterogeneous catalysis; processes of deep processing of hydrocarbonic residues using wave impacts. Processes of the first group are most widely used in industry, combined processes of the second group are used much less often. After successful completion of pilot testing processes of the third group (slurry technology and nanoheterogeneous catalysis) are much forward-looking. The process of the fourth group can become promising for industrial implementation only after experimental analysis of their actual energy efficiency.

The work presents the results of soil and environmental studies on the Bolshoy Solovetsky Island. The main environmental problems in this territory include the presence and operation of production facilities, discharge of untreated water into the White Sea bays, and non-compliance with the established requirements for the storage of municipal solid waste. In order to assess the anthropogenic impact on soils, 44 samples were taken in the summer of 2016-2017. The study included the determination of both physico-chemical and biological indicators. During the study, the differentiation of the soil profile by granulometric composition was revealed: the upper part is heavier and the lower part is lighter, which affected the change in all indicators. A slightly acidic environment has been established for the soils of the studied areas. The average pH of water for all studied samples was 5.7, varying down the profile from the surface from 4.4 to 5.9. The average organic matter content for all samples was 10 %. Its content in the coarse-humus horizon varied from 20 to 36 %, in the eluvial horizon it decreased to 2-3 %, and in the lower horizons of sandy horizons with various inclusions – up to 1 % and lower. The obtained indicators of the content of heavy metals (HM) and petroleum products (РP) were correlated with the accepted pollution levels. Soils in separate trial areas of TM, primarily zinc and lead, as well as petroleum products. The data obtained showed the presence of influence on the soil of three structures - a gas station and a diesel power station, a dry dock. The average value of catalase activity for all studied soil samples from the Solovetsky village amounted to 10.6±0.3 in the surface horizon of the control soil sample was 19±1 mg H2O2 for 1 hour per 3 g of soil. Eliminating the influence of natural abiotic factors, an increase in enzyme activity to 29 units relative to the control sample in soil with a high content of HM (about 10,000 μg/kg) and a sharp (up to 3 units) decrease in activity in soil with a high level of pollution of РP (13400 μg/kg). According to the results of soil research Solovetsky village showed a very high level of contamination at some PPs and a reliable response to this effect of catalase activity. It has been suggested that it is possible to use the activity of this enzyme as a diagnostic indicator of soil contamination in the Solovetsky village with the above pollutants.

The financial statements serve as a benchmark in assessing the financial performance of the company as the basis for making business decisions. The motivation in conducting this research is to support previous research to see the development condition of one of the oil palm plantation companies. The purpose of this study is to assess the financial performance by using financial ratio analysis and horizontal analysis. The method used in this research is Quantitative Descriptive with analysis design using Term series Analysis. The result of the research based on financial ratio analysis shows the liquidity ratio and solvency ratio in good condition, while the activity ratio and profitability ratio are not good because it is below the industry average of similar companies. Based on horizontal analysis, financial performance fluctuated and influenced internal and external factors such as operational performance and the average price of world palm oil. The limitations of this study are using only two analytical tools and financial statements analyzed only the balance sheet and income statement.

Capital Intensive

Enterprise asset management (EAM) systems are used by asset owners and/or operators to manage the maintenance of their physical assets. These assets, including equipment, facilities, vehicles, and infrastructure, need maintenance to sustain their operations. An EAM system provides the means to have less unplanned downtime and extended asset longevity, which offers clear business benefits that improve the profit and loss statement and balance sheet. Particularly for capital-intensive industries, like drilling and exploration, the failure of on-time delivery of critical equipment or processes is disruptive and costs nonproductive time and customer satisfaction. Organizations understand these issues and employ an appropriate asset management system to engineer their asset maintenance and management. An EAM system is needed to manage the people, assets/equipment, and processes. EAMs are used to plan, optimize, execute, and track the needed maintenance activities with associated priorities, skills, materials, tools, and information. Similarly, nondestructive testing (NDT) is used as a tool for integrity assessment of assets in drilling and exploration. The main advantage of using NDT is that the item’s intended use or serviceability is not affected. The selection of a specific technique should be based on knowledge and skills that include design, material processing, and material evaluation. Validating the purpose of this paper, we emphasize the importance of optimizing the asset utilization and serviceability to enhance overall efficiency by integrating EAM software that manages assets, the operation management system (OMS) controlling the processes, and asset inspection management systems (AIMSs).

The problem of losses of oil products from leaks during their storage and transportation at oil supply facilities is considered. The influence of oil product leaks on the environmental situation around oil depots and gas stations is shown. A detailed overview of existing methods and tools for detecting leaks of petroleum products from storage facilities is presented. The evaluation of their effectiveness. Two methods for detecting oil leaks and devices based on them are proposed. The first device monitors the movement of liquid in the tank, the second-detects petroleum products in wastewater. The problem of recovery of petroleum vapors and environmental pollution from the release of vapors of light fractions into the atmosphere is also considered. An overview of existing methods and means of recovery of petroleum vapors is presented. Two methods and devices for capturing oil vapors and returning them to the reservoir are proposed, based on different principles: vapor absorption in the cooled oil product and vapor recovery on the principle of the Carnot cycle. It is shown that these devices can provide effective detection of oil leaks and recovery of their vapors, as well as improve the effectiveness of environmental protection at modern gas stations and tank farms.
