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

2. 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

3. Data LO (top) LCO Acme FCO FO
Miocene nannofossil and foraminifer occurrences in 13 wells

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

5. Mad Dog Miocene Optimum Sequence and Zonation
Predict most likely order of fossil events in the next well !

6. Lower – Middle Miocene RASC Optimum Sequence
GOM – Foraminifera and Nannofossil Events
Lower – Middle Miocene
Predicts order of events in next well
