Preview Questions Geothermal Engineer | Role Specific Skill

Question 1: In geothermal reservoir engineering, what is the main reason for decreased production rates after the initial production surge in a geothermal field?

Which action should you take?

Choose only one option

The reservoir experiences pressure depletion, reducing fluid flow and heat extraction rates

The geothermal fluid becomes too viscous, requiring higher pumping energy to maintain flow

Increased temperature of the geothermal fluid, causing operational issues in heat exchange

Increased mineral scaling in the production wells, leading to lower efficiency

Question 2: Which of the following is the primary advantage of utilizing high-enthalpy geothermal reservoirs in power generation systems?

Which action should you take?

Choose only one option

Higher energy conversion efficiency due to the high temperature of the geothermal fluid

Reduced environmental impact compared to lower-enthalpy systems

Greater availability of renewable energy resources in the form of fluid flow rates

Higher initial capital costs but lower operational costs over time

Question 3: In geothermal reservoir engineering, what is the main purpose of reservoir simulation models?

Which action should you take?

Choose only one option

To calculate thermal conductivity of reservoir rocks

To predict reservoir behavior under different operational scenarios

To monitor water quality in geothermal reservoirs

To estimate the economic viability of geothermal projects

Question 4: Which of the following is a key factor affecting the longevity of a geothermal power plant?

Which action should you take?

Choose only one option

Reservoir sustainability

Fluid flow rate

Well drilling depth

Amount of energy extracted per cycle

Question 5: What is the most common risk associated with overheating during geothermal drilling operations?

Which action should you take?

Choose only one option

Overpressure and blowout risk due to formation fluid entry

Increased fluid viscosity leading to poor circulation

Casing collapse and fluid loss

Damage to the drill bit and downhole equipment failure

Question 6: What is the main limitation of using shallow geothermal systems for heating and cooling?

Which action should you take?

Choose only one option

High installation costs due to the need for deeper boreholes

Lack of availability of geothermal fluids in shallow regions

Inability to provide heating or cooling during peak demands

Limited thermal efficiency due to lower ground temperature and insufficient heat transfer rates
