Available Data
• Interpreted Seismic Lines– needed to determine if you have a trap
• Well-log Lithology– needed for determining whether you have a
reservoir rock (sandstone) and a seal – determine potential source rock (shale)
• Geochemical Analysis– determine if a potential source rock has
generated oil
Instructions
• divide into teams of 3 or 4 explorationists
• your budget is $330,000
• purchase data
• analyze data to choose a spot to drill
Prices
• Seismic Lines– Line A - $100,000– Line B - $75,000– Line C - $75,000
• Well-log Lithology– Well 1 - $25,000– Well 2 - $35,000
• Geochemical Analysis– Well 1 - $5,000– Well 2 - $5,000
