Home OpendTect v4.0 Attributes
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

Examples
Default and user-defined attribute-sets
Ridge Enhancement (faults) & Spectral Decomposition.
Movie-style parameter testing (time gate of Similarity)
Create your own attributes with mathematical expression
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

Reference shift -- Attribute that moves the extraction position in 3D space

Scaling -- Attribute used for scaling of amplitude

SEG-Y checklist -- SEG-Y loading checklist

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
