Interferometric Interpolation of 3D OBS Data
نویسنده
چکیده
I extend the interferometric interpolation of ocean bottom seismic (OBS) data from two dimensional data to 3D data. The sparse OBS data are interferometrically correlated with the model-based Green’s functions for the sea-floor model to generate the densely recorded OBS traces, and a local matching filter is applied to reduce the artifacts in the interpolated data. Information about the source wavelet and the multi-layered velocity model below the sea floor is not needed, and an antialiasing formula is derived. Results with 3D synthetic data show that the OBS traces can be faithfully interpolated from a sparse sampling interval of 50 m × 50 m to a denser interval of 10 m × 10 m.

Interferometric Interpolation and Extrapolation of Sparse 2D OBS Data
We present the theory and numerical results for interferometrically interpolating and extrapolating ocean bottom seismic (OBS) data. For the interpolation of OBS data we use the combination of a natural Green’s function (i.e. OBS shot gather) and a model-based Green’s function for the water-layer model. Synthetic and field data results show that the aliased OBS data with large receiver interval...

متن کاملOptimizing design of 3D seismic acquisition by CRS trace interpolation
Land seismic data acquisition in most of cases suffers from obstacles in fields which deviates geometry of the real acquired data from what was designed. These obstacles will cause gaps, narrow azimuth and offset limitation in the data. These shortcomings, not only prevents regular trace distribution in bins, but also distorts the subsurface image by reducing illumination of the target formatio...

Interferometric Synthetic Aperture Radar (InSAR) technology provides a useful tool for quantitatively measuring the deformation of the earth, influenced by natural factors (earthquake, subsidence, and landslide) and human factors (construction of structures, drilling, and the overexploitation of underground water aquifers). In this context, time-series analysis of radar images allows the monito...
