Reconditioning marine seismic data for interactive interpretation

Seismic data regularization for marine wide azimuth data

Imaging subsalt structures under the complex overburdens is a challenging task in seismic exploration due to the poor illumination of seismic waves. To solve the illumination problem, geophysicists designed the wide azimuth acquisition. Moreover, WAZ acquisition improves the signal to noise ratio by increasing the azimuthal fold, and reduces multiple interferences in the final images (Etgen, 20...

We Need Interactive Data Interpretation Rather Than Interactive Data Visualization

efficiency of coherency attributes in seismic data interpretation

seismic coherency is a measure of lateral changes in acoustic impedance that are caused by variations in structure, stratigraphy, lithology, porosity, and fluid content. seismic coherency is a geometrical attribute that establishes temporal and lateral relationships with other attributes. seismic coherency can be defined by coherency attributes. when coherency attributes are applied to seismic ...

Iterative migration in marine CSEM data interpretation

In this paper we consider an application of the ideas of electromagnetic (EM) migration to the interpretation of a typical marine controlledsource (MCSEM) survey, which consists of a set of sea-bottom receivers and a moving electrical bipole transmitter. The 3-D interpretation of the MCSEM data is a very challenging problem because of the enormous amount of computations required in the case of ...

An Algorithm for Modeling and Interpretation of Seismoelectric Data

Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...
