Underground Sun Conversion - Start

Second Drilling Completed

06/14/2019 | Report

The Underground Sun Conversion project was first started with batch attempts. This means that the gases required for the microbiological reaction are injected into the gas reservoir through a well and the gas mixture is withdrawn again through the same well after a reaction time. From the outset, however, a second storage well was planned to be drilled in order to continue the tests in closed-loop operation, which should enable a far more flexible trial operation.

In the second quarter of 2019, RAG Energy Drilling GmbH drilled the second LESP-001 well in Pilsbach on behalf of RAG Austria AG.

Following the successful testing, the well will represent the second development of the Underground Sun Conversion storage facility.
