RASC

1
RASC CONOP Application in GOM
Mad Dog (GOM) deep water Miocene prospects below
Jurassic evaporites Ultra deep wells (gt 9
km) Poor seismic resolution to identify
turbidite
fairways Identify sand prone strat levels with

microfossils

Methods and Programs Ranking and Scaling (RASC)
version 18
probabilistic
handles large datasets fast
comprehensive error analysis
colour graphics
Constrained Optimization (CONOP) version 9
mostly deterministic
finds solutions by
trial error

RASC - Event Strategy
The average top and base may seem
non-biological, but have an attractive
stratigraphic property error bar.
