Test your understanding: Exploring a Well

Finding hydrocarbons by analyzing subsurface structures with geological and geophysical methods.

• Petroleum Geologist

• Geophysicist

• Geologist

• Reservoir engineer

Manage the technical aspects of drilling exploratory, production and injection wells

• Mud engineer

• Drilling engineer

• Production engineer

• Reservoir engineer

Utilize the structure of reservoir together with well production rates and measured reservoir pressures to analyze and interpret the data in order to optimizme oil and gas recovery.

• mud engineer

• drilling engineer
