RTQC plot of computed far field signature compared to reference signature.
Optimise your acquired seismic data with advanced onboard QC and Processing
Shearwater's onboard QC and processing is setting a new industry standard with shot-by-shot far field estimation and QC using the near field hydrophones. Our onboard QC and processing are available on all our seismic vessels.
We use the same Reveal processing software system that is in our onshore processing centres. The onboard facilities allow for real time quality control of seismic data and also high end Fast Track volumes to be provided as part of the acquisition service.
Standard Onboard QC Processing:
Real Time QC Data Flow
Offline QC Data Flow
Broadband QC Data Flow
QC Brute Stack for every line will be produced with the following processing route
RMS analysis values (Bar) are calculated in order to quantify both noise and signal level in pre-determined target zones
Shearwater Advanced Onboard QC Processing:
Seismic Interference Removal & Online QC
Real-time De-noise using FX-Swell
Source QC using far field signatures generated from near field hydrophones
Identifying & normalising variations in streamer sensitivity during acquisition
