A discovery well drilled in a crestal position logged gas.
Question was posed whether there is a downdip oil rim.
Its presence or absence would demand different development scenarios.
Gassman fluid substitution modeling was used to estimate the wet and oil responses
of the reservoir. Subsequenctly, a 2D synthetic seismic model was built.
It shows that a downdip oil rim would be practically undetectable from the updip gas.
