See what the reservoir model predicts seismically.

Sim2Seis converts dynamic reservoir-model states into elastic properties and synthetic seismic response for direct comparison with observed evidence.

Why it matters

Does the model predict what we observe?

A reservoir model becomes more useful when its predicted response can be inspected against what the seismic evidence actually shows.

Real product evidence

Sleipner survey base map of the observed 4D interval RMS attribute over the same survey area. — Sleipner CO₂ plume, same survey grid and identical map coordinates in both panels. The colour scales are not directly comparable: the synthetic and observed attributes carry different amplitude ranges and units. The comparison here concerns plume geometry and lateral extent, not absolute amplitude.

Interpretation context

Mismatch can indicate where assumptions or the dynamic reservoir model require review. Comparison supports calibration; it does not prove a unique reservoir explanation.
