Seismic Methods in Geothermal Water Resource Exploration: Case Study from Łódź Trough, Central Part of Poland

Figure 4

Correlation of synthetic seismogram (yellow trace) for M1 well with the true seismic section (red and black colour—negative and positive true seismic reflections, respectively) in the Lower Cretaceous and Lower Jurassic geothermal reservoir intervals (orange part of line in Figure 3). Explanations of seismic horizons: Cr₂t: top of the Turonian; Cr₁: top of the Lower Cretaceous; J₃p: top of the Portlandian; J₃km: top of the Kimmeridgian; J₃o: top of the Oxfordian; J₂: top of the Middle Jurassic; J₁to: top of the Lower Jurassic (Toarcian); T₃re: top of the Triassic (Rhaetian).
