How Can Temperature Logs Help Identify Permeable Fractures and Define a Conceptual Model of Fluid Circulation? An Example from Deep Geothermal Wells in the Upper Rhine Graben
Table 1
Temperature anomalies in well GPK-1 in Soultz and GRT-1 and GRT-2 in Rittershoffen. Structural data from the main open fractures in the FZs, as well as the polarity and depth of the anomalies, are presented. Structural data in italics indicate that acoustic images are not available. For GRT-2, values are calculated from oriented calipers [41].
