Product details

OMNI 3D is the industry standard for seismic survey design and modeling. Use OMNI 3D software to plan, execute, and analyze land, marine, transition zone, VSP, and multicomponent surveys. OMNI 3D features an intuitive interface and a versatile multi-project handling capability, both of which allow users to quickly and effectively analyze and monitor their seismic acquisition projects. OMNI 3D 2016 delivers a range of enhancements and quality improvements related to land and marine design, model building, productivity and reliability.

Key components

  • 3D Illumination and Modeling Enhancements and Improvements?include:
    • Display reflection angles and their statistics for each bin using color and overlay displays for an Illumination Analysis employing a 3D Ray Model.
    • For illumination analysis using 3D ray model, display raw reflection angles using the Query Values Wizard and also export reflection angles (raw data and statistics) to a text file.
    • Accuracy of 3D ray tracing algorithm has been modified so as to improve consistency. Decreased the tolerance of the 3D ray optimization routine to find the minimal travel time to increase ray location accuracy and computation time.
    • Increased the maximum number of layers of a 3D ray model from 20 to 100.
    • Adjusted horizon ordering for 3D Ray model diffraction and illumination analysis from shallow to deep depths, which also matches the order in the project data tree.
    • Added additional horizon data validation for 3D Ray and 3D Grid models If OMNI cannot compute elevations from XYZ points, then the program will initialize the horizon to zero and generate a warning/error file.
  • 2D Ray Modeling Improvements:
    • Improved accuracy of the Alias Frequency computation in the Alias Analysis for steeply dipping events.
    • The reflection angle (reported in Reflection and Critical Offset Analysis) now reports a value of 360 when it does not encounter a reflection.
    • Added functionality to load marine data stored in P1/11 format.
  • Users can now load shapefiles from the “Polyline – Edit/Redefine Points” and “Points – Redefined Selected” wizards. This allows users to create surface and fold boundaries, obstacles, detours, contours, sail turns and 2D ray model horizons and wellbores directly from shapefiles.
  • Users can now save streamer preview schematics to an image file.
  • Added a license expiry countdown warning starting from 30 to 0 days.
  • Users can now refresh licensing information after making configuration changes in the Schlumberger License tool without needing to restart the application.
  • OMNI now reports additional header information exported from SEGY stack analysis datasets The X and Y coordinates of the CDP ensemble (bin center location) are now written to byte locations and identified within OMNI 3D trace headers as well as the Inline and crossline information. Users can now load these datasets into other applications for additional processing.
  • When saving intra-array static SEGY filters, information about dip azimuth and inclination angles is now saved to the EBCIDC header and described in the help.
  • When displaying Source and Receiver Array Responses, the number of decimal places displayed by the station weight text is now the same as that displayed in the Color Scale.
  • Added new tutorials including Offset Vector Tiles, Fresnel Fold Analysis, 5D Interpolation Analysis and Transition Zone Survey Design.
