Appendix A. Attributes and filters

Table of Contents

Coherency -- Attribute that emphasizes areas of highest discontinuity
Convolve -- Attribute that returns a filtered response
Delta Resample -- Attribute that enables residual alignment of seismic volumes
Energy -- Attribute that returns the energy of a trace segment
Event -- Attribute that quantifies an event's shape or distance relative to a next event
Fingerprint -- Attribute that computes the similarity between a user-defined vector of attributes and the equivalent vector taken at each position in a cube.
Frequency -- Attribute that returns frequency properties
Frequency Filter -- Attribute that returns filtered data using FFT or Butterworth filter types
GapDecon -- Attribute that aims to attenuate repetitions of primary reflections (multiples).
Horizon -- Attribute that enables advanced calculations on horizons
Instantaneous -- Attribute that returns an instantaneous attribute
Match Delta -- Attribute that extracts time shifts between similar events in different seismic volumes
Mathematics -- Attribute that returns the result of a user-defined mathematical expression
Position -- Attribute that returns any attribute calculated at the location where another attribute has its minimum, maximum or median within a small volume.
Prestack attribute -- This attribute enables you to load, display, use and manage pre-stack data
Reference -- Attribute that returns the definitions of the extraction position
Reference shift -- Attribute that moves the extraction position in 3D space
Scaling -- Attribute used for scaling of amplitude
Similarity -- Attribute that returns trace-to-trace similarity properties
Spectral decomposition -- Attribute that returns the amplitude spectrum (FFT) or waveletcoefficients (CWT)
Velocity Fan Filter -- Attribute that returns energy with apparent velocities inside a specified Min/Max range.
Volume statistics -- Attribute that returns statistical properties
