"Using rock physics we directly link the seismic and the rocks. Forward modelling allows us to find out what the effect of changing any characteristic of geology or petrophysics has on the seismic. If we have a water-wet well we can find out what the seismic would have looked like if it was gas bearing, or oil bearing (or even full of chocolate). It allows us to de-risk potential reservoirs that have been identified on seismic. We can forward model to see what the reservoir 'should' look like if filled with hydrocarbons. If our model of seismic and the actual seismic match, there is a very good chance that our model is correct."
