One of the major challenges of seismic interpretation is seismic to well tie in the depth domain. When seismic is processed through isotropic velocity modeling and migration, we more often than not observe that seismic depth deviates from well depth of the same geological formation.
The criteria of seismic velocity modeling are to match seismic data to well data, to maintain the seismic velocity spatial variation and to avoid any artifacts, such as bull's eyes.
Paradigm well data constrained time-preserving tomography provides the solution. This presentation illustrates technologies, workflows and examples of grid-based and model-based tomography. With these technologies, accurate seismic time to depth conversion or re-depthing can be achieved efficiently by seismic interpreters.
