Seismic fades maps show the areal distribution of seismic fades 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 table below outlines a suggested procedure for mapping seismic fades.
Step | Action |
---|---|
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. |
Example
Figure 1 contains examples of a seismic fades map, an isochron map, and seismic line A–Á (location shown on maps).
