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
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
