  1. Re-utilizing possibilities of abandoned hydrocarbon wells in Northern Hungary P. Szűcs, E. Turai, P. Vass, B. Zákányi, Cs. Ilyés, G. Nyiri, Zs. Fekete, R. Miklós, V. Mádai, F. Móricz, M. Szilvási, R. Kilik, R. MészárosZákányiné University of Miskolc, Faculty of Earth Science and Engineering, Research Institute of Applied Earth Sciences, MTE-ME Geoengineering Research Group 46th IAH Congress - Malaga, Spain 2019 Abstract ID: 336

  2. Well-known fact – the geothermal energy potential is high in Hungary Tóth and Almási 2001 Temperature at the basin bottom (Szanyi and Kovács 2007) Dövényi et al. 1982 Deep over-pressured flow systems originated from the Pre-Neogene basement. Superimposed, shallower, gravity-driven flow system. „Unique natural groundwater laboratory” József Tóth

  3. The increasement and sustainable utilization of geothermal energy in Hungary European Geothermal Congress 2019, Country report by Nádor, Kujbus and Tóth Geothermal community heating: 300 MW capacity (Miskolc 55 MW, Győr 52 MW ) Geothermal energy in agriculture and industry : 360 MW capacity The geothermal heat in balneology and other: 250 MW capacity Geothermal power plant capacity: 3 MWel at Tura (B-ORC) • Many new thermal water related (hydrothermal) projects can be expected in Hungary in the near future – the importance of hydrogeology. Sustainability issues and technical challenges in the main focus of the experts

  4. Good example for sustainability in North Hungary close to Miskolc– 100 % injection rate into a karst aquifer system MAL-PE-01 production well Depth: 2305 m Fluid temperature: 105 °C Yield: 6600-9000 l/min. MAL-PE-02 production well Depth : 1514 m Fluid temperature : >90 °C Yield: 8 000 l/min. KIS-PE-01 reinjection well Depth : 1737 m Receiving capacity: 1600 l/min. KIS-PE-01B reinjection well Depth : 1093 m Receiving capacity : 5600 l/min. KIS-PE-02 reinjection well Depth : 1058 m Receiving capacity : not a final result ~7000 l/min.

  5. PULSE research project – complex investigation of abandoned hydrocarbon wells in order to increase the geothermal energy production UnproductiveCH wells Geothermalwells Pilot project areas in the PULSE project. Database creation, well and area scalegeothermalenergy potential determination Thermal water and abandoned oil and gas wells in Hungary

  6. Research areas – PULSE Project

  7. The maximum available geothermal energy from a given subsurface volume (EG) based on Gazo (1992) where V - volume, Φ - porosity, ρk - density of the rock matrix, ρf - density of the fluid, ck - specific heat capacity of the rock matrix, cf - specific heat capacity of the fluid, T - temperature of the subsurface volume, Tref - reference surface temperature. F.M. Gazo, 1992: Reservoir assessment of the Mak-Ban geothermal field, Luzon, Philippines. UNUG.T.P., Iceland, report 6, pp. 1-32.

  8. The flow chart of the complex evaluation of the abandoned wells in respect to geothermal energy utilization

  9. Expertise evaluation of an abandoned well DEP-24 (DEMJÉN PÜNKÖSDHEGY)

  10. Well-based evaluation for every drilling- Well ID: DEP-24 (DEMJÉN PÜNKÖSDHEGY) • PetroMod modeling • Results: • At present, the DeP-24 borehole in Demjen shows the image shown here based on our rock density, heat capacity and temperature models.

  11. Versatile geothermal fluid compositions in Hungary Concessionareas of Hungary The content of its deepest layer’s dissolvedsolutions Legend Limit value for total dissolved solids for drinking water

  12. Corrosion and scale problems because of the geothermal fluid compositions Mezőkövesd, Zsóryspa

  13. Basin modeling – evaluating the area • The temporal and spatial modeling of sedimentation basins is used in hydrocarbon research. • However, this approach is well suited for thermal history reconstruction during geothermal exploration.

  14. Conclusions • First a database for the whole country were developed. • Later, because of the huge number of available wells, two sample areas were determined, and further examined. • Our aim was to help the decision makers with a useful tool to create geothermal heating or power plant with cost effective methods. • From the two sample areas several wells were examined and valued based on a new method, to describe its usefulness for geothermal energy production. • Later the two areas as a whole will be evaluated for geothermal purposes. • We believe that the proposed method can be applied in any area under any circumstances.

  15. Thank You for Your Attention! The research was carried out within the GINOP-2.3.2-15-2016- 00031 “Innovative solutions for sustainable groundwater resource management” project of the Faculty of Earth Science and Engineering of the University of Miskolc in the framework of the Széchenyi 2020 Plan, funded by the European Union, co-financed by the European Structural and Investment Funds.
