Onboard Quality Control Services // Shearwater GeoServices

Optimise your seismic data with Shearwater’s industry-leading Quality Control tools

Shearwater’s onboard QC provides real time analysis of the recorded data quality thus allowing fast correction of smaller problems as well as optimal decisions on re-shooting. This ensures a high-quality data set while also maximising efficiency.

Real Time Quality Control
Shearwater not only provide all the industry standard Real Time Quality Control (RTQC) tools but also produce industry leading displays which can really make a difference and are truly real time. The displays are monitored by highly-trained staff which combined with our advanced techniques mean that even minor problems are picked up quickly.

Real Time Quality Control Highlights:

Integrated observer and QC geophysicist team

Shot-by-shot far field estimation from near field hydrophones to produce an auto-correlation with the ideal source

Seismic interference monitoring using real time Common-P amplitude maps

Swell noise removal in real-time viewed on both shots and stacks to give an accurate assessment of noise levels

Shots, stacked near fields, near trace, source comparison, cross-feed QC, noise graphs, RMS maps all available in a fully customisable display

Significantly reducing the need to re-work with our QC technology

Offline Quality Control
Shearwater’s offline QC products provide a comprehensive view of the data for our highly experienced geophysicists to ensure that all the details of the data are recorded and addressed fully.
