Seismic data recovery from data with missing traces on otherwise regular acquisition grids forms a crucial step in the seismic processing flow. For instance, unsuccessful recovery leads to imaging artifacts and to erroneous predictions for the multiples, adversely affecting the performance of multiple elimination. A non-parametric transform-based recovery method is presented that exploits the c...

Worldwide interest in shale plays has rapidly increased in recently years, thanks to the combination of horizontal drilling and hydraulic fracturing. Shale formations act as both the source and the reservoir for the natural gas and usually exhibit anisotropic properties at larger scale. Geological and petropysical studies found that the right combination of thickness, TOC (total organic carbon)...

In this paper it is presented a volcanic seismic acquisition equipment that has been developed together with an energy harvesting system, based on piezoelectric elements, in order to work in autonomous conditions. The energy harvesting system has been developed to convert the wind or marine currents energy into electrical energy through a new method based on piezoelectrics. For the deployment o...

Seismic acquisition footprint generally consists of modulations in recorded amplitudes that are spatially correlated to the surface locations of sources and receivers used in a survey. These amplitude variations obscure the true reflection response of the subsurface. In this study, synthetic seismic data were produced using numerical modelling code written in MATLAB. An “exhaustive” dataset was...

We have developed a case study of crosshole seismic tomography with a cross-firing geometry in which seismic sources were placed in two vertical boreholes alternatingly and receiver arrays were placed in another vertical borehole. There are two crosshole seismic data sets in a conventional sense. These two data sets are used jointly in seismic tomography. Because the local sediment is dominated...
