2D seismic data continues to play a vital role in hydrocarbon exploration. Close to a quarter of total seismic acquisitions are 2D. Several reasons justify this type of acquisition, including cost effectiveness (particularly during downturn) and large areal coverage.  In particular, 2D seismic data provides an understanding of the geology in frontier areas; the information captured can then be used for planning future 3D survey acquisition.  

2D seismic data acquisition is being carried out all over the world.  There are many regions where the vast majority of available seismic data is still 2D.  In addition to new acquisitions, there are significant amounts of 2D lines that need reprocessing.

Processing 2D data offers unique challenges.  First, 2D lines can be very large.  Second, a very large number of 2D lines may be involved, often more than one hundred lines.  Processing this data can be human resources intensive, requiring a high level of coordination, synchronization and management.

In this presentation we demonstrate the new, innovative GeoDepth solution for 2D velocity model building and imaging that is part of the Paradigm® 17 release.  We show how our new 2D tools tackle all the challenges mentioned above in an extremely efficient way. We are very proud to present our new solutions, which were developed with an uncompromising aim of improving the quality, usability and productivity of our 2D solutions.

  • Quality - Significantly improve the quality and reliability of velocities from our tomographic solutions.
  • Usability - Enhance the user experience by establishing a new, multi-2D line workflow, with interactive and batch processing capabilities for all applications: Effective and innovative QC tools, multi-2D line job parameterization and job submission.
  • Productivity – Significantly reduce project turnaround time: Process multi-2D lines with minimal effort, and enable better synchronization and job parallelization on clusters for all applications in the workflow, with the aim of reducing computation time.
