Rig operations at Graben-Neudorf geothermal project site, Germany (source: Deutsche Erdwarme)The project is a standard geothermal doublet for power generation aiming to produce both electricity and heat. It includes the realization of two wells reaching a depth of 4,000+ meters, the first completed in August 2023, finding temperatures above 200 °C in the reservoir.
With temperatures higher than expected, the planned operations of the project had to be postponed as the developer sourced for high-temperature solutions.
“With Tenaris, we have found a reliable, high quality and customer-orientated supplier of tubulars and casing accessories, focusing on the specific needs of a geothermal operator like Deutsche Erdwärme and providing excellent after sales service. We are looking forward to a longer business relationship,” says Dr. Sebastian Homuth, operations manager of Deutsche Erdwärme.
“Drilling the first well of Graben-Neudorf has been challenging and Tenaris has been a key partner, accompanying high-quality products with services such as running assistance, interim storage and just-in-time delivery that helped to minimize working capital,” says Karl Reuter, Project Engineer at Zueblin.
“Tenaris has always shown a high level of flexibility, understanding our operational needs and support in short time to every kind of request,” adds Mr. Reuter.
