Pump 6002_Artificial Lift - Gas Lift and Plunger Lift

_______________________

Question 1: The plunger lift system component labeled "F" in the diagram is called:

A - Standing valve B - Pig C - Bumper D - Lubricator _______________________________________________

Question 2: Plunger lift systems lift collected fluids to the surface in small, manageable slugs. In order to achieve small slugs, a "pig" is installed in the tubing and run vertically in the tubing. The pigging cycle depends upon the: A - Casing length and diameter B - Amount of collected fluids C - Total amount of reservoir fluids D - Inner diameter of the tubing

_______________________________________________

Question 3: As fluid travels up the tubing in a natural-flowing oil well the reduced density:

A - Reduces the fluid column height above the formation B - Reduces the fluid column weight above the formation C - Increases the fluid column weight above the formation D - Negates the fluid column weight above the formation _______________________________________________

Question 4: You have just completed a gas lift system for a wellhead. As you are finishing, another nearby wellhead about a kilometre away has a pressure drop and you recommend a gas lift system be installed at that wellhead as well. The manager asks you to use the design specifications of the system you just designed to build another one. Your reply would be: A - No, each gas lift system is different and each requires a unique design B - Yes, the wellheads are close together and should have similar reservoirs C - Yes, this will save time and money D - No, you can't use two gas lift systems that close together _______________________________________________

Question 5: Which of the following gas lift processes results in the injected gas increasing in volume and pushing liquid ahead of it, reducing fluid column weight:

A - Displacement B - Expansion of gas C - Reduction of fluid density D - None of the above _______________________________________________

Question 6:

Gas lift processes offer several advantages over other artificial lift processes. These advantages include all of the following except: A - They are not affected by wellbore deviation B - In most cases, they are capable of handling sand C - The producing rate is controlled at the surface D - Low capital cost of gas supply equipment _______________________________________________

Question 7: The gas lift process that injects a gas into the reservoir to reduce fluid density, which in turn reduces fluid column weight is called the: A - Gas expansion process B - Hydrostatic pressure enhancement process C - Displacement process D - Reduction of fluid density process _______________________________________________

Question 8: A gas lift system is designed to normally function through the top valve.

A - True B - False _______________________________________________

Question 9: There are basic principles in a gas lift system. In the displacement process, large gas bubbles that act as pistons are introduced to displace: A - Air bubbles B - Liquid slugs C - Solids suspended in the fluid D - All of the above _______________________________________________

Question 10: The basic principle of how a gas lift system functions is the: A - Introduction of additional gas into the reservoir to increase pressure below the surface B - Introduction of water into the reservoir to increase pressure below the surface C - Use of a gas-driven pump to force reservoir fluids to the surface D - Forcing the reservoir gas back into the reservoir to increase sub-surface pressure _______________________________________________

Question 11: The plunger lift system component labeled "B" in the diagram is called:

A - Bumper B - Controller C - Lubricator D - Standing valve _______________________________________________

Question 12: In a plunger lift system, the wellhead production is directed to a:

A - Compression unit B - Separator C - Heat exchanger D - Transmission pipeline metering facility _______________________________________________

Question 13: Plunger lift systems are typically installed in gas wells troubled by loading with accumulated liquids at the bottom of the well. When the liquid problem becomes significant, the loading will result in: A - Reduced production B - Increased reservoir-to-surface fluid velocity C - Increased gas pressure D - Increased production _______________________________________________

Question 14: Advantages offered by the plunger lift process include: A - No external energy is required to lift the fluids B - Low operating costs C - Formation of hydrates and paraffins may be prevented D - All of the above _______________________________________________
