Mezocsat, Hungary has published a tender for well rehabilitation work to convert an existing gas well to geothermal for potential district heating application.
The municipality of Mezocsat in Hungary has published a tender for rig services related to the repurposing of an idle gas well into a geothermal well. The intention is to connect this well to a newly developed district heating system, thus partially displacing the use of natural gas for heating in 13 municipal properties.
The tender has been posted in the EU public procurement gazette.
The subject of the tender is the Mezocsat-1, a hydrocarbon exploration well located on the border of the settlement in which the project will be implemented. The well was drilled in the 1990s to a depth of around 1071 meters.. The scope of the contract will involve well reentry, cleaning, perforation, downhole surveys, and well testing. When all the rehabilitation work is completed, the well is forecasted to have a yield of about 700 liters per minute at temperatures of about 57 °C.
The deadline for submitting bids if on 24 April 2026.
The “Utilization of Geothermal Energy Development in Mezocsát” project, supported by the Swiss Fund, was announced in January 2025. A similar initiative in the nearby city of Bogacs is also being supported by the Swiss Fund.
