“I have been using Pegasus for several of our seismic processing projects and have found it to be a very cost-effective and efficient tool. Pegasus has been used to QC contractor picked velocity fields and for generating new pick fields. Pegasus has tools that enable the identification of velocity outliers and to quickly review their validity and to modify if required. The ability to review the full and far angle stack response whilst picking has been an effective tool and has enabled confident picking of primary reflections in difficult areas. Support has been excellent with quick response to requests for changes and with help learning how to use Pegasus effectively.”

“Makaira Geotechnical loves the efficiency and speed of velocity QC with Pegasus, in fact we reckon it is quicker and better to get the gathers from the contractors and to either pick the velocities ourselves or QC their velocities.”
