Diverter (wellhead)

Incorrect. This is the function of a choke or valve, not a diverter.

Correct! The diverter's main purpose is to divert fluids away from the wellhead.

Incorrect. This is not the function of a diverter.

Incorrect. This is the function of a flow meter, not a diverter.

Incorrect. Routine production typically does not require the use of a diverter.

Correct! Diverters are crucial during blowouts to control and direct the uncontrolled flow.

Incorrect. While a diverter may be used as a safety precaution, it's not strictly necessary for valve replacement.

Incorrect. This is done with a pressure gauge, not a diverter.

Incorrect. This describes components of a typical wellhead system, not a diverter.

Correct! These are the essential components of a wellhead diverter.

Incorrect. These are components of a wellhead system, not a diverter.

Incorrect. These are components of the wellbore, not a diverter.

Incorrect. While a diverter can contribute to safer operations, its primary benefit is safety, not efficiency.

Correct! By diverting fluids away from the wellhead, the risk of environmental contamination is significantly reduced.

Incorrect. The use of a diverter does not directly reduce maintenance costs.

Incorrect. A diverter does not increase wellhead pressure.

Incorrect. Subsurface diverters are located below the wellhead.

Incorrect. Flowline diverters are installed in the flowline, not directly at the wellhead.

Correct! Surface diverters are positioned above the wellhead, directing fluids to a pit or tank.

Incorrect. "Choke diverter" is not a standard term for a type of diverter.

Here is a possible solution to the exercise:

1. Activate the Emergency Shutdown System: Immediately engage the emergency shutdown system to isolate the wellbore and reduce flow as much as possible. This typically involves closing emergency valves or triggers on the wellhead.
2. Open the Diverter Valve: Locate the wellhead diverter valve and manually open it. This will direct the flow of fluids away from the wellhead and into the diversion pipe.
3. Adjust the Choke Manifold: The choke manifold allows for controlled throttling of the flow rate. Carefully adjust the chokes to regulate the flow of fluids into the diversion pit or tank, ensuring safe and efficient diversion.
4. Monitor the Diversion System: Continuously monitor the diversion system, checking the flow rate, pressure, and any potential leaks or malfunctions.
5. Maintain Safety Precautions: Throughout this process, prioritize safety. Ensure all personnel are wearing appropriate safety gear, maintain a safe distance from the wellhead and diversion system, and follow all relevant safety protocols.
6. Communicate and Coordinate: Maintain clear communication with all crew members and supervisory personnel, ensuring everyone is aware of the situation and the necessary steps being taken.

Important considerations:

• Emergency response plan: Refer to the wellsite's emergency response plan for detailed instructions on handling a well blowout.
• Training: Ensure all crew members are adequately trained on the operation and safety procedures related to the wellhead diverter and blowout control.
• Equipment condition: Regularly inspect and maintain the wellhead diverter system to ensure its functionality.
