Processing of Seismic Data

Seismic data processing

Click to EnlargeSeismic data from more than 80 mines in 16 countries across the world stream continuously into our offices. Approximately 30,000 daily seismic events are processed by a team of 80 data processors 24 hours a day, 365 days a year and returned to the mine typically within minutes of the event being recorded on the mine. The aim is to have all data processed back on the mine within one hour of it being recorded, with large events receiving highest priority.

The processors are assisted with their task using travel time plots and per-event Wadati plots. These check consistency of picks with checks on unusual source parameters popping up messages on the screen to aid the processors while processing.

Quality control

Quality control of the seismic data is performed every working day. Events which triggered the wadatiprocessor-assist automatic pop-ups, large events and a random selection of rejected and accepted events are quality controlled. If this selection of events fail, the whole batch of data is queued for reprocessing with another quality control once the data is reprocessed.

This processed data is then used in the routine reporting and notifications sent out to customers.
