Instructions: Choose the best answer for each question.
1. What is the defining characteristic of a High Pressure, High Temperature (HPHT) well?
a) A bottom hole temperature exceeding 100°F (38°C). b) A maximum anticipated pore pressure exceeding a hydrostatic gradient of 0.5 psi/ft. c) A wellbore pressure exceeding 5,000 psi.
The correct answer is **b) A maximum anticipated pore pressure exceeding a hydrostatic gradient of 0.5 psi/ft.** While HPHT wells do have high temperatures and pressures, the defining characteristic is the high pore pressure, exceeding a specific gradient.
2. Which of these is NOT a challenge posed by HPHT wells?
a) Material degradation due to high temperatures. b) Increased safety risks due to potential well control issues. c) Enhanced production rates due to high pressures.
The correct answer is **c) Enhanced production rates due to high pressures.** While high pressures can lead to improved recovery, it is not a challenge associated with HPHT wells. The other options are all challenges faced in these environments.
3. What is a key strategy for overcoming the challenges of drilling HPHT wells?
a) Using standard drilling equipment and materials. b) Minimizing pre-drilling planning and analysis. c) Employing advanced materials resistant to high temperatures and pressures.
The correct answer is **c) Employing advanced materials resistant to high temperatures and pressures.** Standard materials and minimal planning are not effective in dealing with HPHT conditions.
4. What is a significant benefit of exploring and producing from HPHT reservoirs?
a) Access to untapped oil and gas reserves. b) Lower production costs compared to conventional wells. c) Reduced environmental impact due to lower energy demand.
The correct answer is **a) Access to untapped oil and gas reserves.** HPHT reservoirs hold significant resources that would be otherwise inaccessible, contributing to the global energy supply.
5. How does the industry ensure wellbore stability and safety during HPHT drilling?
a) Relying solely on experienced drillers and their intuition. b) Utilizing continuous monitoring and control systems. c) Ignoring potential risks to maximize production.
The correct answer is **b) Utilizing continuous monitoring and control systems.** Real-time monitoring is crucial for managing wellbore conditions and ensuring safety during HPHT operations.
