[15.3.2024] The first borehole is currently at a depth of approximately 160 metres and thanks to the drill core we now have a detailed idea of the geological structure and further laboratory analyses are underway to measure, for example, the heat capacity of the target rocks or the thermal conductivity, collectively referred to as the geothermal properties of the rocks. Each metre of core is carefully scanned (see picture) on a 360-degree, high-resolution scanner, allowing further analysis to be carried out without needing to physically access the samples. The data from the samples will be sent to colleagues at the Technical University of Darmstadt in Germany, where they will be fed into the conceptual models and subsequently parameters for the individual BTES underground storage fields will be calculated. In the coming days, the work will continue through the Cenomanian aquifer into another important rock layer, the so-called Permacarboniferous rocks, which is, among other things, important for the high-temperature BTES, which will reach 400 to 500 m.
Drilling operations supplied by Anger&Söhne company are coordinated by the RINGEN technical team on regular inspection days, which are also attended by the Litoměřice mining engineer who supervises the drilling process. This is also recorded in digital reports which contain information on e.g. drilling strings speed, drilling performance (depth, ROP) etc. All this information is available to all project partners, who can also monitor current status of the well remotely.
