Recovering elevation in seismic datasets using Google Earth: A case study of Parnaíba Basin

Autor: Martin Tygel, Jorge H. Faccipieri, Tainá Souza, S. Dany Rueda

Publikováno v: First Break. 39:37-42

Static corrections, especially in old land data, can be a challenging issue for adequate seismic processing and imaging. A frequently encountered problem is the lack of reliable elevation data for sources and receivers. In this work, we propose a sim

Enhancement of diffractions in prestack domain by means of a finite-offset double-square-root traveltime

Autor: Martin Tygel, Tiago A. Coimbra, Leiv-J. Gelius, João H. Speglich, Jorge H. Faccipieri

Publikováno v: GEOPHYSICS. 84:V81-V96

Exploration of redundancy contained in the seismic data set assures enhancement of images that are based on stacking results. This enhancement is the goal of developing multiparametric traveltime equations that are able to approximate reflection and

Stretch-free generalized normal moveout correction

Autor: Rodrigo Bloot, Tiago A. Coimbra, Jorge H. Faccipieri

Publikováno v: Geophysical Prospecting. 67:52-68

The effective application of normal moveout correction processes mainly depends on four factors: the chosen traveltime approximation, the stretching associated with the given traveltime, crossing events and phase changes, the last two being inherent

Common-reflection-surface method in weakly anisotropic vertical transverse isotropic media

Autor: Tiago A. Coimbra, Rodrigo Bloot, Jorge H. Faccipieri, Martin Tygel

Publikováno v: GEOPHYSICS. 83:C99-C113

The extraction of kinematic parameters from wave propagation through traveltimes is one of the great challenges in seismic data processing. In this context, we modify the common-reflection-surface (CRS) traveltime to improve its accuracy and also int

Common-reflection-point time migration

Autor: Tiago A. Coimbra, Dany S. Rueda, Jorge H. Faccipieri, Martin Tygel

Publikováno v: Studia Geophysica et Geodaetica. 60:500-530

Since the early days of seismic processing, time migration has proven to be a valuable tool for a number of imaging purposes. Main motivations for its widespread use include robustness with respect to velocity errors, as well as fast turnaround and l

Stacking apertures and estimation strategies for reflection and diffraction enhancement

Autor: Leiv-J. Gelius, Tiago A. Coimbra, Martin Tygel, Jorge H. Faccipieri

Publikováno v: GEOPHYSICS. 81:V271-V282

It is well known that the quality of stacking results (e.g., noise reduction, event enhancement, and continuity) can be greatly influenced not only by the traveltime operator chosen but also by the apertures used. We have considered two so-called dif
