Hybrid model integrating predictive analytics and environmental adaptation

Oleksandr Pashchenko — Mon, 08 Sep 2025 00:00:00 +0200

The research investigates industrial maintenance strategies in the oil and gas sector and proposes a hybrid model that adapts maintenance schedules based on real-time environmental data. 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.

Optimization of petrophysical laboratory measurements

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.

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.

Hydrological causes and consequences of the water inrush into the Praid Salt Mine, Transylvania, Romania

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.
