ENSCHEDE, Netherlands --New velocity model building and pre-stack depth migration software is available from dGB Earth Sciences and Geokinetics. Developed with support from Gaz de France and OMV, the software runs in Opendtect and has three closed source plugins.
"Costs and quality of PSDM processing are largely dependent on the time-consuming, manual process of building and updating velocity models," says Gaul de Groot, president and CEO of dGB Earth Sciences. "Reducing cycle times means you can run more iterations in less time and thus produce higher quality PSDM outputs at lower cost. This is what we aimed for when we started to develop this system three years ago.
"The first release of VMB includes vertical update – and horizon-consistent update modules. Velocity gridding, horizon picking, 3D body generation and QC are performed in OpendTect Base; the Open Source part of the system. The design of the new system is such that it can support multiple PSDM processing systems. All structures needed to interface a PSDM system to OpendTect-VMB are released in the Open Source domain."
