Introduction The K horizon
• The K horizon is a seismic reflector present in the whole Larderello-Travale geothermal area • Its 3D reconstruction was done through the interpretation of 2D/3D seismic data in time
Larderello Lago
Travale
Venelle_2 well
• In the Lago area, where the Venelle_2 well is located, the K horizon reaches its shallowest elevation (about 3000 - 3500m depth) • Depth estimation from velocity information coming from VSP and logs data

H and K horizons seem to be separated by the presence of a transition zone characterized by a decrease in the amplitude of the seismic signal. H and K have been interpreted as two separate horizons.
Mining target H and K horizons
Based on velocity values coming from the integration between the VSP data and available check-shots in the area, the estimated depths are as follows:
