SeisImager/2D refraction software is a fully integrated refraction modeling and interpretation software package that runs on your Geometrics seismograph or PC. Before you leave for the field, determine the best way to configure your survey by drawing a geologic cross-section of the site and performing a simulated survey with sophisticated modeling software. Change the model so you can see what targets are detectable. Identify first breaks quickly with an accurate automatic picker, with manual override. Clean up noisy data with comprehensive filtering and view all your prior picks simultaneously for shot-to-shot coherence. QC your data before analysis to ensure that your answer will be the most accurate. Display differences between travel time curves to distinguish layering and refractor topography. Automatically resolve reciprocal time conflicts that cause inaccuracies in depth estimation. Choose from three methods of analysis to best suit the geologic conditions. Take a quick look with a 2 or 3-layer time-term analysis. If you prefer traditional methods, use the delay-time (reciprocal) method and view the process step-by-step. If you expect lateral velocity variations, use the optimized tomographic analysis that runs quickly and accurately. A field (Lite) version of SeisImager/2D comes free with all Geometrics Windows-based seismographs.

SeisImager/2D Software Packages

  • Standard version: for use on seismograph with mouse or PC with mouse; allows up to 16K samples per trace, 128 traces per shot, 360 traces per interpretation, and 65 shots per interpretation.
  • Professional version: for use on seismograph with mouse or PC with mouse; allows virtually unlimited input up to 2M samples per trace, 48K traces per shot, 48K traces per interpretation, and 48K shots per interpretation.
  • Lite version: included with purchase of Geometrics Windows-based seismographs. For use on seismograph with mouse or PC with mouse; allows up to 16K samples per trace, 64 traces per shot, 51 traces per interpretation, and 12 shots per interpretation.
  • Demonstration version: for use on PC with mouse, may be launched 15 times; same allowances as Lite version; no printing capability.
  Note: The number of shots per spread and spreads per interpretation are dependent on the actual trace number used. The Standard and Professional versions are also available for rent.
