Complex seismic trace analysis
The conventional seismic trace can be viewed as the real component of a complex trace which can be uniquely calculated under usual conditions. The complex trace permits the unique separation ofExpand
SEMBLANCE AND OTHER COHERENCY MEASURES FOR MULTICHANNEL DATA
The concept of semblance is introduced, along with a descriptive review of several of the more common likeness or coherence measures. Measures are considered from three points of view: the domain inExpand
Velocity spectra-digital computer derivation and applications of velocity functions
Multifold ground coverage by seismic techniques such as the common reflection point method provides a multiplicity of wave travel path information which allows direct determination ofExpand
Poststack velocity analysis by separation and imaging of seismic diffractions
Small geologic features manifest themselves in seismic data in the form of diffracted waves, which are fundamentally different from seismic reflections. Using two field-data examples and oneExpand
LONG PERIOD SEA-FLOOR MULTIPLES AND THEIR SUPPRESSION*
Multiple sea-floor reflections in deep water often are not effectively suppressed by either CDP stacking nor standard predictive deconvolution methods. These methods fail because the reflectionExpand
Surface consistent corrections
Amplitudes of seismic reflections have been of interest since the first days of exploration seismology. Any change of amplitude or anomalous behavior may be significant, so it is important that theExpand
A unified method for 2-D and 3-D refraction statics
Most of the seismic data processing procedures are divided into 2-D, 2.5-D, crooked lines or 3-D versions dictated by the differences in the shot and receiver configurations. In this paper, weExpand
ESTIMATION AND CORRECTION OF NEAR‐SURFACE TIME ANOMALIES
The problem of computing static corrections for CDP seismic reflection data is discussed. A new approach is presented and it is related to various existing approaches. The approach consists of usingExpand
Post-Stack velocity analysis by separation and imaging of seismic diffractions
Small geological features manifest themselves in seismic data in the form of diffracted waves, which are fundamentally different from seismic reflections. Using two field data examples and oneExpand
Seismic attributes revisited
Since their introduction in early 1970`s seismic attributes have become one of the most commonly used and powerful interpretation tools. In earlier applications they were considered as a managementExpand
