GeoThrust has been designed with a workflow architecture to obtain an accurate earth model and earth image in time and in depth from data recorded with irregular geometry in areas with rough topography, complex near-surface, and complex subsurface, with uncompromisingly high technical specifications for data analysis and quality control, but easy to learn and easy to use. The near-surface model is estimated by nonlinear tomography applied to first-arrival times that accounts for topography and resolves lateral and vertical velocity variations. Aside from statics corrections, the corrections for the near-surface are performed by wavefield dating - an essential requirement for imaging from irregular topography. GeoThrust performs subsurface velocity estimation, modeling and imaging from topography, not from a flat datum, based on rms and interval velocities estimated at reflector positions, not at reflection positions.

Advanced velocity determination and 3D/2D velocity model building create accurate, high-quality, interpretable seismic images in time and depth. A complete suite of interactive and batch velocity analysis tools for anisotropic models easily handles the full range of seismic imaging problems. Integration with interpretation and modeling solutions streamlines the workflow while preventing data loss and honoring geologic constraints. Easy construction of accurate 3D and 2D models, regardless of the structural geology’s complexity. Highly parallelized for running efficiently on very large 3D datasets and multi-line 2D datasets, on-premise or in the cloud. Accurate seismic images and depth models are essential in hydrocarbon exploration and production. The Aspen GeoDepth velocity determination and modeling system offers a solution for improved seismic imaging in time or depth through the integration of interpretation, velocity analysis, model building, time-to-depth conversion, etc.
