Extending the seismic signal frequency towards the low frequencies has become almost standard on Vibroseis seismic projects, owing to the benefits it provides in terms of vertical resolution, signal penetration, inversion workflow results or ease of interpretation.
However, the emission of this new low-frequency bandwidth is associated with levels of distortion much higher than with the conventional sweep bandwidth, owing to the inherent design of seismic vibrators based on hydraulic actuators.
Several solutions have been proposed in recent years to prevent the generation of this distortion, but their field implementation remains thus far
quite restricted due to either limited performance or proprietary technologies, not commercially available to third parties.
Discover more about the new approach for reducing the low-frequency distortion, embedded in the vibrator electronics itself and easy to implement and use during seismic operations.
