“…A high amplitude reflector was correlated with fractured contact-metamorphic rocks, which account for over 70% of the total geothermal fluid produced at the Travale area. Other small-scale 3D and 2D seismic surveys for fractured geothermal reservoirs are known from Japan (Matsushima et al 2003), New Zealand (Lamarche 1992) and the United States (Majer 2003).…”

“…The different approaches and various processing techniques with all their assumptions, advantages, and pitfalls have been developed largely for the HC industry and are described in detail in numerous and often voluminous textbooks (Sheriff and Geldart, 1995;Keary, Brooks, and Hill, 2002). A very good summary of seismic approaches for the geothermal context is given by Majer (2003a).…”

“…Seismic interpretation forms part of an integrated workflow for mapping and characterization of subsurface deposits (Brown 2011;Herron 2011), with applications ranging from hydrocarbon (Ashcroft 2011) and geothermal exploration (Majer 2003;Bredesen et al 2021) all the way to monitoring of carbon capture and storage sites (Mulrooney et al 2018;Angelo et al 2019). It is traditionally divided into two components: structural and quantitative interpretation.…”

Summary Structural seismic interpretation and quantitative characterization are historically intertwined processes. The latter provides estimates of the properties of the subsurface, which can be used to aid structural interpretation alongside the original seismic data and a number of other seismic attributes. In this work, we redefine this process as an inverse problem which tries to jointly estimate subsurface properties (i.e., acoustic impedance) and a piece-wise segmented representation of the subsurface based on user-defined macro-classes. By inverting for the quantities simultaneously, the inversion is primed with prior knowledge about the regions of interest, whilst at the same time it constrains this belief with the actual seismic measurements. As the proposed functional is separable in the two quantities, these are optimized in an alternating fashion, where each subproblem is solved using the Primal-Dual algorithm. Subsequently, the final segmented model is used as input to an ad-hoc workflow that extracts the perimeter of the detected shapes and produces a structural framework (i.e., seismic horizons) consistent with the estimated subsurface properties. The effectiveness of the proposed method is illustrated through numerical examples on synthetic and field datasets.
