The power is under your fingertips!™
SeisOpt® @2D automatically and accurately reveals subsurface velocity structure even in laterally complex geologic environments.
Figure 1. Run the optimization, visualize and analyze the velocity model and make final figures. Use the ‘tuner’ to further fine-tune the optimized velocity model and/or create new velocity models and use SeisOpt® @2D as a bidding module.
SeisOpt® @2D visualizes subsurface ray coverage before you leave the field.
Figure 2. Use the virtual survey design module to visualize and optimize subsurface ray coverage and your seismic array during data acquisition, thus saving both time and money. Know your target is sampled before leaving the field.
SeisOpt® @2D provides visual and quantitative tools so you can test the accuracy of your velocity models. Export the picks and fits for plotting with MS-Excel.
Figure 3. The SeisOpt® @2D Graphical User Interface allows you to compare first-arrival travel time picks to theoretical travel times calculated through the velocity model, for each seismic source.
SeisOpt® @2D MakeEps™ provides users with the ability to produce report quality figures. Adjust, label and crop final figures, then write them to a portable format for final output.
Figure 4. Using MakeEPS, final figures can be saved in encapsulated PostScript format. This can then be imported into other popular programs for further editing or incorporation into report text.
What is the Technology behind SeisOpt® @2D?
SeisOpt® velocity optimization software achieves a globally optimized velocity model using only first arrival travel time data and array geometry as input. SeisOpt requires no prior assumptions of subsurface structure, or any other subjective data, as input. SeisOpt technology is now being used throughout the world for geotechnical, mining and petroleum applications. The technology is based on a nonlinear optimization method called generalized simulated annealing. The algorithm performs repeated forward modeling, where new models are conditionally accepted or rejected based on a probability criterion. This criterion allows the algorithm to escape from non-unique, local, travel-time minima to achieve a unique, globally optimized model of subsurface velocity structure. The algorithm makes no assumptions on the orientation of the subsurface velocity gradient, and can therefore reveal vertical structures and strong lateral gradients, if present. The method is therefore ideal in areas characterized by strong lateral velocity gradients, and in areas with extreme topography or complex near-surface structure where the user has little or no prior knowledge of subsurface structure.
