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.

Multisensor GeoStreamer is the ideal platform for broadband imaging. Deep towing reduces weather impact and improves acquisition efficiency. Recorded signal is insensitive to variations in towing depth or local sea-surface variations, significantly reducing non-repeatable noise on reservoir monitoring projects. Pre-stack amplitude and phase are consistent in an angle-dependent and frequency-dependent manner. Rich low-frequency signal enhances Full Waveform Inversion (FWI) and improves the accuracy of subsurface property prediction. Multisensor wavefield separation enables better shallow illumination. Near-surface images unaffected by acquisition footprint effects can be used for standalone interpretation. Enhanced broadband resolution of stratigraphy assists the recovery of small time shifts related to changes in reservoir saturation and pressure during reservoir monitoring projects. GeoStreamer uses both hydrophones and velocity sensors to remove all free-surface ghost reflections.
