Tech Paper Depth Domain Inversion Case Study in Complex Subsalt Area
Conventional amplitude inversion assumes that the seismic amplitudes are correctly located and can be inverted to derive a true representation of the rock properties.
Remove unwanted noise while preserving signal quality
This noise degrades image quality, hampers interpretation, and distorts the seismic signal prior to inversion and other reservoir-definition stages.
Our anomalous amplitude attenuation (AAA) workflow addresses a range of different noise modes, including marine swell noise, seismic interference, biological noise, ground roll, air blast, wind noise, near-surface scatterers, and cultural noise. It is applicable to all types of seismic data—land and marine, legacy and new acquisition.
We use sophisticated time and space spectral analyses to identify and attenuate anomalous noise zones within the seismic record. The data-adaptive process leaves the seismic record untouched in areas where noise contamination is small, maintaining high signal fidelity.
Customers around the world have used the AAA workflow to enable completion of projects on schedule and avoid downtime due to weather, reshoots, and other delays.
