Advanced velocity determination and 3D/2D model building allow for accurate, high-quality and interpretable seismic images in depth and time. An integrated suite of interactive and batch velocity analysis tools allows you to easily solve all kinds of seismic imaging problems. The workflow is simplified by integration with interpretation and modeling tools. Data loss is prevented and geologic constraints are respected. No matter how complex the structural geology, it is easy to create 3D and 2-D models. Highly parallelized to run efficiently on large 3D datasets as well as multi-line 2D datasets. Hydrocarbon exploration and production requires accurate seismic images and depth models. Aspen GeoDepth velocity calculation and modeling system provides a solution to improve seismic imaging in depth or time. It integrates interpretation, velocity analysis, model construction, time-to-depth conversion, and more.
