Comparative analysis shows that traditional strategies either cause inefficiencies or incur high failure risks. The hybrid approach integrates predictive analytics with environmental inputs such as corrosion and weather conditions. Simulations demonstrate a 15% reduction in failure rates and annual cost savings of up to $15 million per facility. The model enhances operational resilience, optimizes resource use, and aligns with the industry's transition toward safer and more sustainable practices.</p> 2025-09-08T00:00:00+02:00 Copyright (c) 2025 Geosciences and Engineering https://ojs.uni-miskolc.hu/index.php/geosciences/article/view/4135 Optimization of petrophysical laboratory measurements 2025-09-05T09:10:31+02:00 Roland Dócs docs@afki.hu Khalat Shorsh Mohhamed khalat.shorsh@gmail.com Hazim Nayel Abdelfattah Dmour hazin.dmour@uni-miskolc.hu Zoltán Turzó zoltan.turzo@uni-miskolc.hu Krisztián Mátyás Baracza krisztian.baracza@uni-miskolc.hu <p>Although petrophysical measurements in today’s hydrocarbon industry are highly advanced and well-established, there remains considerable room for optimization, particularly in laboratory measurement techniques. While data acquisition methods in the field generally provide reliable and consistent results, the laboratory-based analysis of core and fluid samples often face challenges related to measurement precision, standardization, and efficiency. Factors such as sample handling, preparation procedures, and the limitations of traditional experimental setups can introduce uncertainties that impact reservoir evaluation. By refining laboratory protocols, adopting advanced instrumentation, and integrating modern analytical methods, the accuracy and reproducibility of petrophysical laboratory measurements can be significantly improved, ultimately leading to better reservoir characterization and more effective resource management.</p> <p>In this context, the measurement procedures carried out at the Petrophysical Laboratory of the Institute of Applied Earth Sciences, University of Miskolc, were examined with the aim of optimizing both the measurement methodology and the evaluation methods.</p> 2025-09-13T00:00:00+02:00 Copyright (c) 2025 Geosciences and Engineering https://ojs.uni-miskolc.hu/index.php/geosciences/article/view/4134 Hydrological causes and consequences of the water inrush into the Praid Salt Mine, Transylvania, Romania 2025-09-04T12:31:39+02:00 Balázs Kovács kovacs.balazs@gama-geo.hu <p>The Praid salt mine, Romania was flooded by the Corund Creek in May 2025, which changed the hydrodynamic and environmental conditions of the site. To provide an overview of the situation, we discuss the geological processes forming the salt diapir, highlighting its hydrogeological aspects. We also present the previous mining activities, and the most probable process of the water intrusion into the mine areas. Since a new situation arose as a result of the inrush of water, we analyze the hydrodynamic processes of the recent (flooded) state and we give an outline of future possibilities.</p> 2025-09-20T00:00:00+02:00 Copyright (c) 2025 Geosciences and Engineering https://ojs.uni-miskolc.hu/index.php/geosciences/article/view/3711 Some aspects of the radio-magnetotelluric method and instrumentation development 2025-06-16T13:08:06+02:00 Laszlo Vincze laszlo.vincze@geoelectro.hu <p class="Abstract"><span class="rynqvb"><span lang="EN-US">In recent decades, the demand for shallow geophysical methods and instruments has changed significantly.</span></span> <span class="rynqvb"><span lang="EN-US">Today, there is only a need for methods and instruments that can provide a large amount of accurate measurement results in a short time, which are suitable for developing effective inversion procedures.</span></span> <span class="rynqvb"><span lang="EN-US">Only contactless methods can meet the speed requirement.</span></span> <span class="rynqvb"><span lang="EN-US">The measurement technique is significantly simplified if we can use a signal source that is of natural origin or an artificial source created for other purposes (e.g. radio transmitters).</span></span> <span class="rynqvb"><span lang="EN-US">The radio-magnetotelluric method (RMT), which can be considered an extended variation of the popular very low frequency (VLF) method in terms of frequency range, is exactly such a method.</span></span> <span class="rynqvb"><span lang="EN-US">Another advantage is that the created field can be considered a plane wave, thus simplifying the data processing and interpretation procedures.</span></span> <span class="rynqvb"><span lang="EN-US">This study presents a brief history of the development of VLF-RMT methods, the evolution of instruments, the development of processing methods, the characteristics of modern inversion methods, and then summarizes the aspects of designing a modern RMT instrument.</span></span></p> 2025-10-22T00:00:00+02:00 Copyright (c) 2025 Geosciences and Engineering
