C - The pitch or length of each cavity within the pump
D - The counter-clockwise rotation of the sucker rods PUMP 6005_Artificial Lift - Submersible Pump System
_______________________________________________ Question 1: If operating without a gas separator causes an underload condition of a submersible pump, the appropriate remedial action is:
A - Check the surface pressures and re-establish the annular flow path B - Lower the casing pressure or choke back the well slightly C - Wait until the reservoir pressure increases and displaces the pump with fluid D - Choke back the wellhead to restrict flow _______________________________________________
Question 2: Low tubing pressure experienced with a submersible pumping system can be caused by a/an:
A - Gas locked pump due to gas surge or restricted casing valve B - Increase in plant inlet pressure C - Restricted wellhead choke D - Obstruction in the flowline _______________________________________________
Question 3: The submersible pump system component that contains a thrust bearing assembly that is designed to withstand the differential forces created while pumping is called the: A - Multistage centrifugal pump B - Equalizer section C - Gas separator D - Motor flat extension _______________________________________________
Question 4: The equalizer section is attached on top of the motor that drives a submersible pump. One of its primary functions is to: A - Provide a path through which motor oil can expel to the annulus to prevent seal or motor housing rupture B - Ingest and then centrifugally separate liquids from gas C - Provide a conduit to transfer electrical power from the surface to the submersible motor D - Provide a fluid tight seal to facilitate the transfer of electrical power from the motor flat to the submersible motor _______________________________________________
Question 5: A reliable check valve should always be installed in the equalizing line od a submersible pump system to:
A - Allow operating in a downthrust condition B - Prevent operating in a downthrust condition C - Prevent the circulation of produced fluid down the annulus D - Allow the circulation of produced fluid down the annulus _______________________________________________
Question 6: An equalizer section is attached on top of the motor that drives the submersible pump. One of its primary functions is to: A - Provide a conduit to transfer electrical power from the surface to the submersible motor B - Act as an isolation chamber to prevent contamination of the motor oil from annular fluids C - Ingest and then centrifugally separate liquids from gas D - Transmit torque to the pump shaft, which spins impellers _______________________________________________
Question 7: The submersible pumping system component that accommodates for thermal expansion and prevents contamination of the motor oil is referred to as a: A - Motor flat extension B - Vent box C - Seal section protector D - Motor controller _______________________________________________
Question 8:
Fluid levels provide insight into well performance once the well has stabilized. An increase in fluid level with a decrease in rate could indicate: A - Restricted inflow B - Increased reservoir pressure C - A hole in the tubing D - Presence of asphaltenes _______________________________________________
Question 9: In the case of a pumped off well, to allow continuous run, it is necessary to: A - Turn off the underload settings B - Maintain the underload settings at the current level C - Turn the underload settings to maximum D - None of the above _______________________________________________
Question 10: When starting a submersible pump after prolonged non-producing periods, it is often necessary to temporarily:
A - Decrease the overload shutdown B - Increase the overload shutdown C - Lower the high-pressure shutdown switch D - Increase the high-pressure shutdown switch _______________________________________________
Question 11:
High tubing pressure can be caused by:
A - Gas-locked pump due to gas surge or restricted casing valve
