Interactive seismic processing
SEG Technical Program Expanded Abstracts 1988, 1988The high speed of super-computers has made possible the short turn-around-time required for interactive data-processing. Advances in the quality of graphic display devices and higher datatransmission speeds have meant new possibilities for data acquisition and processing QC and for workstation based interpretation systems.

Geostatistical Seismic Data Processing: Equivalent to Cassical Seismic Processing + Uncertainties!
Proceedings, 2011Geostatistical ``filters'' using Factorial Kriging are increasingly used for cleaning geophysical data sets from organized spatial noises that are difficult to get rid of by standard geophysical filtering. The understanding and handling of such kind of spatial processing is not easy for geophysicists who are neither used nor trained to handle ...

Scalable parallel seismic processing
The Leading Edge, 1996Seismic methods, the primary tool in the search for oil and gas, are used to produce images of the earth’s subsurface that explorationists can analyze for geologic structures with hydrocarbon potential.

Seismic interferometry vs. static corrections in seismic data processing
Arabian Journal of Geosciences, 2021The attenuation of distortion caused by the shallow layer generates reliable subsoil’s pictures, which static corrections attempt to do, under the assumption of surface consistency. However, such an assumption is frequently invalid, and nowadays, this problem is still unsolved.

Monitoring Seismic Processing For Seismic Reservoir Characterization
International Petroleum Technology Conference, 2009This reference is for an abstract only. A full paper was not submitted for this conference. Abstract Seismic reservoir characterization (for instance, inversion) requires a well-controlled seismic signal that can sometimes not be guaranteed by conventional processing QCs. One option is to use borehole

Anisotropic seismic data processing
Proceedings, 1996It is known that in areas with significant shale content, the isotropic assumption in seismic data processing is not correct, and this can lead to misfocusing of dipping events and wrong depth positioning if not properly accounted for.

Mountain front seismic processing
SEG Technical Program Expanded Abstracts 2008, 2008Summary Over the last few decades the Colombian foothills area has been explored with mostly 2D seismic data. Repeated efforts to process and reprocess the 2D data gave little hope of achieving a good image of the subsurface. In the last five years 3D seismic was acquired over the intricate part of the mountain front.

Seismic wavelets model so many signals, including seismic source signatures, and are a main part of the seismic convolution model. They can be classified in various types. This chapter discusses various types of wavelet and their importantce. Also, it presents seismic wavelet processing as a method to shape the seismic wavelet, i.e., reduce its effect ...

GêBR: a free seismic processing interface
12th International Congress of the Brazilian Geophysical Society & EXPOGEF, Rio de Janeiro, Brazil, 15–18 August 2011, 2011There are many programs for processing seismic data that are freely available and widespread, for example Seismic Un*x, Madagascar, FreeUSP, and SEPlib, among others. All these packages consist of packages of command-line-oriented programs that are designed to be used in sequence; the data conceptually flow in a pipeline through one program after ...

Seismic Imaging and Processing with Curvelets
69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007In this paper, we present a nonlinear curvelet-based sparsity-promoting formulation for three problems in seismic processing and imaging namely, seismic data regularization from data with large percentages of traces missing; seismic amplitude recovery for subsalt images obtained by reverse-time migration and primary-multiple separation, given an ...
