Instructions: Choose the best answer for each question.
1. What is the primary function of the flow cross in a wellhead?
a) To connect the wellhead to the surface pipeline. b) To act as a central hub for connecting and controlling valves. c) To measure the flow rate of fluids from the well. d) To regulate the pressure inside the well.
The correct answer is b) To act as a central hub for connecting and controlling valves.
2. Which valve is typically positioned above the flow cross?
a) Swab valve b) Wing valve c) Master valve d) Choke valve
The correct answer is c) Master valve
3. What is the main purpose of the swab valve in a flow cross?
a) To regulate the flow of fluids during production. b) To control the flow of fluid during swabbing operations. c) To isolate the well from the pipeline. d) To prevent backflow from the pipeline.
The correct answer is b) To control the flow of fluid during swabbing operations.
4. How many connections does a flow cross typically have?
a) Two b) Three c) Four d) Five
The correct answer is c) Four
5. Which of the following is NOT a benefit of the flow cross design?
a) Simplified flow control. b) Increased production rates. c) Efficient swabbing. d) Enhanced safety.
The correct answer is b) Increased production rates.
Scenario: You are working on a wellhead with a flow cross. The well is currently producing oil and gas. You need to temporarily isolate the oil flow to perform maintenance on the oil pipeline.
Task: Explain the steps you would take to isolate the oil flow using the flow cross and its associated valves.
1. **Close the Master Valve:** This will completely isolate the well, stopping the flow of both oil and gas. 2. **Open the Wing Valve connected to the gas line:** This will allow the gas to continue flowing to its designated pipeline. 3. **Close the Wing Valve connected to the oil line:** This will isolate the oil flow from the well and the pipeline. 4. **Open the Swab Valve:** This allows you to check for any residual oil flow to the oil line and ensure the isolation is complete. **Explanation:** By using the flow cross, you can selectively isolate the oil flow while maintaining the gas flow, facilitating the necessary maintenance without interrupting the entire production process.
