Aspects of Energy Saving of Oil-Producing Enterprises

Increasing energy efficiency is included in the UN Sustainable Development Goals (SDGs) to be achieved by the year 2030. Enhancing energy efficiency is also one of the priority areas for improving the operational efficiency of any oil production enterprise. The energy management system of enterprises has been founded and implemented on the basis of the international standard ISO 50001:2018 and it works successfully. The energy efficiency strategy is formulated in the energy policy and integrated into the business model of the companies. Companies receive significant energy savings in the exploration and production segments through technical, technological, and organizational measures. This article shows the main directions for improving the energy efficiency of the artificial lift well stock and the results of their implementation. The main constraints on the implementation of the energy efficiency policy of oil-producing enterprises have been identified and directions for improvement of energy-saving structure have been proposed. The article proposes strategic-level classification of energy-saving measures, which is based on assessment and comparison of implementation costs, payback period, and takes into account investments into artificial lift technology, therefore allowing investment priorities in the energy management sphere to be distinguished. Advanced directions for investment in oil-production technology have been identified, and an algorithm of development and implementation of key indicators of energy consumption efficiency has been proposed.

Comparative Life Cycle Assessment of Co-Processing of Bio-Oil and Vacuum Gas Oil in an Existing Refinery

The co-cracking of vacuum gas oil (VGO) and bio-oil has been proposed to add renewable carbon into the co-processing products. However, the environmental performance of the co-processing scheme is still unclear. In this paper, the environmental impacts of the co-processing scheme are calculated by the end-point method Eco-indicator 99 based on the data from actual industrial operations and reports. Three scenarios, namely fast pyrolysis scenario, catalytic pyrolysis scenario and pure VGO scenario, for two cases with different FCC capacities and bio-oil co-processing ratios are proposed to present a comprehensive comparison on the environmental impacts of the co-processing scheme. In Case 1, the total environmental impact for the fast pyrolysis scenario is 1.14% less than that for the catalytic pyrolysis scenario while it is only 26.1% of the total impacts of the pure VGO scenario. In Case 2, the environmental impact of the fast pyrolysis scenario is 0.07% more than that of the catalytic pyrolysis and only 64.4% of the pure VGO scenario impacts. Therefore, the environmental impacts can be dramatically reduced by adding bio-oil as the FCC co-feed oil, and the optimal bio-oil production technology is strongly affected by FCC capacity and bio-oil co-processing ratio.

Analysis of the Influence of Gas Distribution on Flora Structure and Oil Displacement Effect During Microbial Oil Displacement

In the context of the rapid development of my country's social economy, the total demand for energy in my country's industrial production continues to increase, of which petroleum energy is an important type of energy required in industrial production. At present, China's petroleum energy mainly depends on imports, so in order to promote the productivity of China's petroleum industry, we must carry out comprehensive innovation of oil displacement technology. Microbial oil displacement is an important technical means, which needs to accurately grasp the factors affecting the oil displacement effect, so as to optimize and innovate the technology. Therefore, this paper will deeply study and analyze the influence of gas distribution on flora structure and oil displacement effect in the process of microbial oil displacement, and put forward some reasonable opinions and measures to further promote the improvement of oil production technology.

A new direction of increasing the efficiency of oil production from bitumen

Oil production and use have become a priority element in ensuring the existence of human society and one of the main areas of research. Despite the abundance of publications on this topic, there is a gap in the development. Available publications don't contain information about the possibility of obtaining associated goods, which could reduce production costs. The aim of the study is to fill the gap by searching for technology that provides the opportunity to obtain associated marketable products in the form of metals. The research methodology used to achieve the goal combines the methods of systematizing and analyzing the available data on oil production technology and metal leaching technology with an integrated technology assessment at the expert assessment level. The results of the study include a proposal for the extraction of metals from oil-bearing rocks by leaching methods. The essence and mechanism of a fundamentally new technology for mining reserves of oil fields by leaching metals from ores during the integration of underground processes of oil pyrolysis and leaching of metals from oil-bearing rocks, combining the possibilities of mine-borehole development and physicochemical leaching processes, are described. The advantages of the new technology are formulated. The obtained results provide an answer to the objectives of the study and indicate the achievement of the goal.

Scenario Analysis for Future Oil Demand and Supply on the Horizon of 2022

This study indicates signs of recovery in the oil price beyond 2020 and predicts oil prices will reach $80 in 2022. This scenario posits an opposite view to a large number of experts who believe that oil prices will remain low for a long time. The second less preferred scenario predicts oil prices of $60 in 2022 due to a big spread in shale oil production technology worldwide, combined with a significant increase in oil production costs.
