Seismic facies maps show the areal distribution of seismic facies and are useful when making lithofacies interpretations. The most common and useful parameters to be mapped are seismic reflection patterns and isochrons (thickness measured in seconds of two-way time).

Procedure

The steps below outlines a suggested procedure for mapping seismic facies.

  1. Identify sequences that contain potential traps, seal rocks, reservoir rocks, or source rocks.
  2. Make regional seismic reflection pattern maps and isochron maps of those sequences. If possible, make maps of lowstand, transgressive, and highstand systems tracts.
