... costs for mobilization. The use of a conventional excavated mud pit to place airguns is susceptible to numerous challenges: failing to maintain stability throughout the airgun actuation compromises its integrity and that of the data (i.e., variable airgun signature and early termination of job...

To capture a quantitative assessment of the 4D signature, a sensitivity analysis on the 4D implications of various fracture physical properties and survey parameters is conducted. The modeling results suggest...

... property, and the Valle del Tigre project further north. Analyses of the airborne geophysical responses, using 2D-3D inversions, show that well-defined resistivity low and magnetic low signatures similar to those at Fruta del Norte, are also observed at Rio Zarza and extend to depth.

..., we selected known deposits to establish airborne geophysical signatures related to the mineralization. Magnetic data was used to enhance shallow sources and map intrusion extents and fertile structural zones. Radiometric data was used to map mafic-ultramafic rocks of low responses. Magnetic anomaly...

... Full waveform inversion (FWI) requires an accurate estimation of source signatures. Indeed, the coupling between the source signatures and the subsurface model can make small errors in the former to translate into significant errors in the latter. When direct methods are used to solve...

.... Operators largely rely on time-lapse seismic surveys as a reservoir monitoring tool, however, it remains challenging to interpret seismic signatures for mapping flow pathways. Meeting this challenge requires developing a rock physics framework that rigorously underpins seismic/acoustic signatures...
