Geothermal Energy volume 4 , Article number: 13 Cite this article. Metrics details. The Alsace region, with its hundreds of previous drillings and seismic history related to both oil and potash exploitation, has been shown to have high subterranean temperatures.
Thus, the sedimentary portion of the well approximately 1. The main challenge of this work is therefore to re-interpret the old well data to provide precise and detailed chrono-lithostratigraphic logs for GPK-1 and GPK-2, especially in their sedimentary portions.
Both sites have been explored by deep drilling operations aiming to exploit the heat extracted from a deep granitic basement Palaeozoic covered by a stack of 1. Thus, the Rittershoffen chrono-lithostratigraphic logs have been used as a baseline to interpret the sedimentary succession in GPK-1 and GPK In conclusion, all the well logs are compared for stratigraphic comparisons.
In addition, a structural analysis was made to more precisely define the limits of the geological formations observed and to present more arguments for the presence of fracture zones or faults.
In this region, there are thousands of oil wells and seismic profiles, which have highlighted the high temperatures in both the sediments and the basement Haas and Hoffmann These high subterranean temperatures have led to different geothermal projects in the Alsace region. To maximize the geothermal exploitation, the main development goal involves reaching the highest temperature and flowrate conditions at the shallowest depth.
