Your Action following your manager’s approval:
1. Thermal maturation modeling – find out in what depth the proposed
formations are mature
2. Mapping: locate the mature source rocks, i.e. the deep locations where the
proposed formations are in the depth range determined in point 1.
3. Find out reservoir rocks
4. Mapping structures where the reservoir rocks may form traps
