• Pressure tests at high-pressure gas stations
  Pressure testing at gas stations is an important element of technical commissioning. Their purpose is to verify that the installation or device can withstand the required pressure and that there are no leaks. Experience has shown that performing pressure testing of process lines hydraulically leads to operational problems due to water remaining in piping and fittings, causing problems such as freezing of regulator silencers, hydrate formation, and ice formation, which can then appear in impulse lines. Therefore, this article provides arguments for performing pressure testing pneumatically, regardless of the pressure level and piping diameter, while maintaining an appropriate safety regime... dalej
• The Role of Drilling Technologies in the Energy Transition and Sustainable Development
  The term “drilling technologies” encompasses activities aimed not only at the drilling and construction of wells for geological characterization, but also at the exploration and production (E&P) of oil and natural gas reservoirs. It should be emphasized that these technologies are applied to the exploration and exploitation of geothermal water resources and natural (white) hydrogen accumulations, the drilling of geoengineering and injection wells for CO2 sequestration, as well as the construction of underground infrastructure using trenchless methods.
  The article demonstrates that, in the context of contemporary challenges related to the energy transition, rising energy demand, and the geopolitical situation, drilling technologies constitute an indispensable technological “tool” As they advance toward more sustainable solutions, they may constitute one of the key pillars of a modern energy system and play a significant role in shaping the future directions of the energy transition... dalej
