Workflows for Interpreters

Using a workflow-driven user interface, the Emerson portfolio of Workflows for Interpreters offers unique, best-in-class technologies in the same integrated platform where day-to-day interpretation is performed.  Advanced functionalities, such as seismic classification, advanced visualization, geobody picking, quantitative seismic interpretation, and others, are available directly within a comprehensive interpretation environment, with no need to move to specialized software from third-party vendors. 

With a seamless workflow, consistent user interfaces, and common viewers, Emerson Workflows for Interpreters eliminate all of the challenges associated with moving data between platforms, including the risk of data duplication, loss of data integrity, etc.  The integrated workflow improves productivity while also enabling faster product adoption and a reduced learning curve.

      • Launching applications (in internal testing, improvement of 30% in large multi-survey projects, due to parallelization)
      • Saving seismic volumes
      • Saving incrementally edited horizons (in internal testing, two orders of magnitude for very large horizons)
      • Opening grids and picks (load up to 4 at the same time - in internal testing, up to 70% faster, due to parallelization)
  • Optimizes productivity, even when working with very large data and/or large, multi-survey projects
  • Outcrop Data
    • A new functionality for importing outcrop-measured dip/azimuth data (bedding, faults and other planar data types) into Epos

  • Of special benefit to users working with onshore, poor-quality seismic, particularly (but not only) in mountainous areas. 
  • Enables users to validate which of the dipping structures they see in a seismic section correspond to horizons and faults, through comparison with dips measured in the field on outcrop data.
  • Usability improvements to ruler in 2D SeisEarth  windows
  • Facilitates accurate geodetic measurements, which are fundamental to the seismic interpretation workflow. 
  • Plotting Templates
    • Ability to save and restore layouts associated with plots
  • The ability to create templates that make a simple comparison between maps and sections representing different geological surfaces and/or scenarios of interpretation make users’ work significantly easier.
