“…The resulting final image features higher coherency than that presented in Alcalde et al (2013) throughout the entire seismic volume. The improvement is mainly due to the calculation of a more precise static model, the improved noise reduction and the source wavelet matching method applied.…”

“…The subsurface stratigraphy includes a carbonate Jurassic sequence that hosts a deep saline aquifer and a high-quality seal formation. This stratigraphy motivated new interest in the area as the structure could be considered feasible for geological storage of CO 2 (Orr, 2004;Baines and Worden, 2004;Alcalde et al, 2013).…”

“…The interest in the Hontomín structure motivated the acquisition of a number of multidisciplinary data sets intended to characterize the Hontomín site (e.g., Alcalde et al, Elío et al, 2013Elío et al, , 2013Ogaya et al, 2013;Ugalde et al, 2013). The active seismic experiments carried out in the area were initially discussed in Alcalde et al (2013). These included a 3-D seismic reflection data set, acquired with the aim of obtaining a 3-D image of the Hontomín structure.…”

“…The processing flow (Table 2) was designed and implemented in order to enhance the S/N ratio and image the target structures. Alcalde et al (2013) applied a standard processing to the 3-D data set. A review of this preliminary processing was conducted to identify some key data/noise issues associated with the data set.…”

Abstract. The Basque-Cantabrian Basin of the northern Iberia Peninsula constitutes a unique example of a major deformation system, featuring a dome structure developed by extensional tectonics followed by compressional reactivation. The occurrence of natural resources in the area and the possibility of establishing a geological storage site for carbon dioxide motivated the acquisition of a 3-D seismic reflection survey in 2010, centered on the Jurassic Hontomín dome. The objectives of this survey were to obtain a geological model of the overall structure and to establish a baseline model for a possible geological CO 2 storage site. The 36 km 2 survey included approximately 5000 mixed (Vibroseis and explosives) source points recorded with a 25 m inline source and receiver spacing. The target reservoir is a saline aquifer, at approximately 1450 m depth, encased and sealed by carbonate formations. Acquisition and processing parameters were influenced by the rough topography and relatively complex geology. A strong near-surface velocity inversion is evident in the data, affecting the quality of the data. The resulting 3-D image provides constraints on the key features of the geologic model. The Hontomín structure is interpreted to consist of an approximately 10 7 m 2 large elongated dome with two major (W-E and NW-SE) striking faults bounding it. Preliminary capacity estimates indicate that about 1.2 Gt of CO 2 can be stored in the target reservoir.
