Attribute-set
|
|
- Various attributes and filters like Energy, Frequency, Similarity, Instantaneous, Band pass filters, Absorption quality factor etc…
- Spectral Decomposition with Fourier transforms and Continuous Wavelet transforms
- Mathematical and logical expressions to create your own attributes and filters
- Movie-style parameter testing ( time gate or step out) to quickly find the optimal settings for your attributes

Attributes List
|
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
