Judicious integration of interpretation methods can help determine the geotechnical risk when evaluating hydrocarbon traps. However, few quantitative evaluations of stratigraphic traps have been documented; those require quantitative integration of seismic and well data, which is performed digitally on a workstation, and require that seismic time, as well as amplitude and phase attributes, tie at existing wells.

The process requires rigorous data preparation, based on seismic petrophysics, that in-cludes integration of techniques (seismic, sonic, ultrasonic), integration of scales, and integration of disciplines.

In the following case study, I analyze all aspects of the hydrocarbon system associated with a stratigraphic trap...
