While seismic data plays an important role in characterizing unconventional plays, a major challenge is to precisely map the formations in depth using such data. Activities such as well planning and geosteering require accurate depthing. Although the earth model is much better represented through a set of optimized anisotropic parameters, mis-ties remain when seismic interpretation is correlated to the well tops.
Paradigm’s well data-constrained, time-preserving tomography provides a stable and systematic solution that can be invoked at any stage of the velocity modeling workflow. This presentation illustrates the technologies and workflows using an Eagle Ford shale play as an example. With this solution, accurate seismic time-to-depth conversion or re-depthing can be efficiently achieved.
