2D Multi-line Grid-based Tomography
Enhanced usability, productivity and quality in 2D velocity model building workflows.
The vast majority of available seismic data in many regions around the world is still 2D, and 2D data represents approximately 25% of new seismic acquisitions. 2D projects can contain up to hundreds of lines, requiring significant investment in human resources and data management. As 2D lines can be very long, cluster-based computing is often required.
now provides an efficient solution to these challenges, through support for a full multi-2D line workflow for 2D grid tomography. Multi-line 2D tomography uses a similar workflow, user interface, and parameters to those used in 3D grid tomography.
An advanced multi-line capability enables work on a large number of lines (from a few dozen up to several hundred) with minimal user intervention. The solution supports both single 2D lines, and work in batch mode. Individual jobs are distributed over the cluster.
“We’ve been testing the new high-productivity, GeoDepth 2D grid tomography, multi-line workflow introduced in Paradigm 17. This has been a result of a collaborative effort between Spectrum and Paradigm geoscientists and developers, and is a great example of Paradigm’s attention to customer needs. We can already see a significant reduction in project cycle time and better end results.”
