Chapter 5. Production Engineering by Mary Gonzalez Quiz Question 1.
Which statement accurately describes gradient curve’s calculation? Answer
A. Pressure traverse calculations are used to calculate the overall pressure drop
over a considerable distance in the well
B. For the calculation of traverse curves we need to divide the total distance into
small segments (in each segment, flow properties/ dp/dz are same), then add
the pressure drop in each segment to get the overall pressure drop in the well.
C. Pressure traverse calculations can be performed by:
By fixing the length increment and finding the pressure drop over this increment.
D. Pressure traverse calculations can be performed by:
By fixing the pressure drop and finding the depth interval over which this pressure drop would occur E. All of the above Question 2.
Flowing Pressure gradient curves are generated for a specific: Answer A- Tubing size B- Producing rate C- Flowing temperature D- All of the above E- None of the above Question 3.
Effects of variables on well performance: Answer
A- Increasing GLR up to a point has a beneficial effect on decreasing liquid hold up.
B- Increase of liquid rate will increase liquid holdup and fluid velocity.
C- A higher Pwf is required to lift a column of fluid as fw increases. D- All of the above E- None of the above Question 4. lOMoARcPSD| 36991220
Assuming the same data from well in example 9. This time the Whp = 480 psig;
GLR= 200 scf / stb. Calculate the Pwf available while lifting the fluid to the surface. ( kh ng c ex9 ) Answer A- Pwf= 3600 psig B- Pwf= 6300 psig C- Pwf= 4960 psig D- Pwf= 4690 psig E- None of the above Question 5.
Effects of variables on well performance: Answer
A- As the tubing size increases, the velocity of the mixture decreases, eventually
velocity will be too low to lift the liquids to the surface
B- The liquid viscosity will affect liquid holdup to some degree and will decrease
the shearing stresses in the liquid and the friction pressure drop.
C- The well will begin to load up with liquids and may eventually die if the tubing size is eventually too small D- All of the above E- None of the above Question 6.
Assuming the same data from well in example 10. This time the separator
pressure is fixed at 200 psig; GLR= 600 scf / stb. Calculate the required wellhead
pressure for flowline sizes of 2 in. (kh ng c số liệu của Ex 10) Answer A- Pwh= 700 psig B- Pwh= 820 psig C- Pwh= 780 psig D- Pwh= 860 psig E- None of the above Appeals
