Article provides a brief overview of the complications arising during the construction of oil and gas wells in conditions of abnormally high and abnormally low formation pressures. Technological properties of the solutions used to eliminate emergency situations when drilling wells in the intervals of catastrophic absorption and influx of formation fluid have been investigated. A technology for isolating water influx in intervals of excess formation pressure has been developed. The technology is based on the use of a special device that provides control of the hydrodynamic pressure in the annular space of the well. An experiment was carried out to determine the injection time of a viscoelastic system depending on its rheology, rock properties and technological parameters of the isolation process. A mathematical model based on the use of a special device is presented. The model allows determining the penetration depth of a viscoelastic system to block water-bearing horizons to prevent interformation crossflows and water breakthrough into production wells.

Segregation Modeling in Stockpile Using Discrete Element Method

et al. 2022

During stockpile feeding, the small particles migrate to the center of the stock while large particles end up around the edges. This phenomenon influences how the mineral is fragmented in the subsequent stages of size reduction. In this study, the primary variables involved in this phenomenon were studied using the discrete element to simulate particle segregation. Results show that the ratio between coarse and fine particles strongly affects particle segregation. The segregation phenomenon was not observed when there were fewer coarse particles in the mix. The feeding height was also found to influence segregation and to affect the angles of repose and dumping. Finally, the rounded polyhedral shape of particles generated the simulation performance most similar to actual particle segregation based on a case study analyzed.

The Arctic region is well-known as a source of energy and mineral resources. Developing these resources by means of responsible practices could provide the world’s economy with strategically and critically important types of minerals. As a result, the role of the Arctic’s resource potential and the approaches used to develop it are gradually changing. In current conditions, it is crucial to strike a balance between existing needs and long-term demand for traditional energy sources or critical materials, such as rare and rare-earth minerals. Achieving this balance will result in sustainable growth, meeting ESG agenda targets while considering national security priorities, and devising novel approaches to sustainable project financing. However, there is controversy between existing strategies and plans based on low-carbon development and reality, which creates new macroeconomic and geopolitical obstacles that need to be overcome. The primary goal of this research is to substantiate the necessity of transforming the Russian Arctic’s mineral resource exploration in the context of global and national changes. The article presents a comprehensive analysis of the contemporary trends and tendencies influencing the exploration of the Arctic’s resources, as well as a general vision of the current situation in the energy sector. Research methods include content analysis and synthesis, generalization, decomposition, elements of strategic analysis, planning and forecasting, statistical methods, econometric modeling methods, and scenario planning. An upgraded concept of sustainable development based on six key components is proposed and discussed. Recommendations are provided on how to improve the existing system of long-term planning and forecasting to reduce the high level of macroeconomic and geopolitical uncertainty. The role of Russian Artic resources is determined in light of the shift in resource use.
