The Ukrainian company “Interpipe” has joined the implementation of the Polish geothermal project POLICE GT-1, aimed at studying the hydrogeological conditions in the city of Police. The data collected as part of the project may serve as a foundation for creating a modern heating system based on the use of geothermal energy.

Technical Features of Pipes for Geothermal Wells
As part of its participation in the project, “Interpipe” supplied casing pipes with a diameter of 13 3/8 inches, intended for the intermediate casing of the well. The pipes are made of L80 grade steel, which is characterized by increased strength. They are specially designed for use in geothermal exploratory and appraisal wells, where significant loads must be sustained at great depths.
To enhance operational reliability, the products have been engineered for resistance to buckling while ensuring optimal wall thickness. Corrosion-resistant alloys have been used to operate in challenging conditions of high water mineralization, guaranteeing protection against chloride corrosion and extending the lifespan of the pipes.
Drilling Features and Project Results
The project involved drilling a vertical well to a depth of up to 2400 meters (with a possible deviation of 10%) to obtain thermal water with a temperature of at least 70 °C and a projected yield of 250 cubic meters per hour. In fact, drilling was completed to a depth of 2165 meters.
“This is one of several geothermal projects currently being implemented in Poland. We are proud to be a partner in this development. We continue to actively promote semi-premium (UPJ-SP) and easy-to-run (UPJ-QR) solutions for geothermal applications, strengthening our expertise and positions in the market,” said Bartłomiej Kania, Sales Manager for OCTG in Continental Europe.
