A team of geologists and geophysicists from the National Institute of Geophysics, Geodesy and Geography (NIGGG-BAS), the Geological Institute (GI-BAS), the University of Mining and Geology (MGU) and Sofia University (SU) has developed, as part of the \u201cGeothermPro\u201d project, an integrated methodology for the accelerated exploration and assessment of the potential of geothermal areas. It is based on the combined application of modern geological, hydrogeological, and geophysical methods. The main objective of the development is to create a scientifically sound and practically applicable approach for locating and assessing promising geothermal structures while reducing the risks and uncertainties associated with future drilling and engineering activities.<\/p>\n

As part of the project, field surveys were conducted in the Kazichene\u2013Ravno Pole area of the Sofia Sedimentary Basin, including magnetotelluric (MT), geomagnetic, electrical (SP), and seismic (HVSR) measurements. The data obtained were processed, analyzed, and integrated into a unified geological-geophysical and geospatial model, enabling a comprehensive assessment of the subsurface environment and geothermal potential. The magnetotelluric surveys were conducted at 26 sites using the Metronix equipment purchased under the project and a parallel configuration with a reference station to improve data quality and mitigate the impact of industrial noise.<\/p>\n

The methodology developed ensures a systematic approach: from the analysis of available information and the planning of fieldwork to data processing, spatial integration, modeling, and quantitative resource assessment. Particular emphasis is placed on the use of multi-method data and their verification which significantly increases the reliability of the interpretation and supports engineering decision-making.<\/p>\n

The project results were presented at a specially organized workshop titled \u201cUnlocking Geothermal Potential \u2013 An Integrated Geological-Geophysical Approach: From Data to Real Energy Solutions,\u201d held on May 27, 2026, at NIGGG-BAS. The developed methodology demonstrates the potential for application in a real-world environment (TRL 6) and lays the foundation for future implementation in the exploration and sustainable use of geothermal resources in Bulgaria.<\/p>\n

The GeothermPro project is funded under the Recovery and Resilience Facility, managed by the Bulgarian Academy of Sciences under the Recovery and Resilience Plan pursuant to Agreement No. PVU-47 of December 6, 2024 \/BG-RRP-2.017-0013-C01\/<\/p>\n
