Information
In well control operation, there are several methods to kill the well which will be performed depending on the well situation. In several occasions, the circulation can be performed; you can do typical well kill procedures as driller’s method or engineering methods. However, there are few cases when the circulation is not possible, you may need to kill the well with other methods. Therefore, this quiz will help you learn about well kill procedures in well control. In this test, there are a total of 20 quizzes relating to well killing procedures.

Question 1 of 20
1. Question
Which well kill method does not require circulation?
Correct
Incorrect
-
Question 2 of 20
2. Question
Which well kill procedure will not maintain bottom hole pressure
Correct
Incorrect
-
Question 3 of 20
3. Question
What does this formula (0.052 x Mud Weight x True Vertical Depth) represent?
Correct
Incorrect
-
Question 4 of 20
4. Question
Which is the correct U-Tube equation from the following?
Correct
Incorrect
-
Question 5 of 20
5. Question
For the following parameters, calculate the Hydrostatic pressure head.
Well vertical depth = 9,000 ft TVD
Mud weight = 12.0
Pressured sand with a reservoir pressure = 6,500 PSI @ 9,000 FT TVD
What is kill weight mud required for this case?
Correct
Kill weight mud = 6,500 ÷ (0.052 x 9,000) = 13.9 ppg
Incorrect
Kill weight mud = 6,500 ÷ (0.052 x 9,000) = 13.9 ppg

Which is the correct statement about the Driller’s method from the following?
Correct
Incorrect
-
Question 8 of 20

How many circulations of the drilling fluid are required in Engineer’s method (wait and weight) of well control?
Correct
Incorrect
-
Question 9 of 20
9. Question
Fill in the blank for the following statement about wait and weight of well control method. Whenever the pump speed is increased or decreased, (including start-up and shutdown) the casing pressure must be held ______ at the value it had immediately before the pump speed change was initiated.
Correct
Incorrect

Question 10 of 20
10. Question
The following table shows sample drillpipe pressure schedule for the wait and weight method:
From the following, which is the correct statement about the above table?
Correct
Incorrect
-
Question 11 of 20
11. Question
What is the Final Circulating Pressure (FCP)?
SIDPP = 400 psi
Well depth = 10,000’ MD/ 9,000’TVD
Current MW = 11.0 ppg
SCR = 500 psi
Correct
KWM = 400 ÷ (0.052 x 9,000) + 11.0 = 11.9 ppg
FCP = 500 x (11.9 ÷11.0) = 541 psi
Incorrect
KWM = 400 ÷ (0.052 x 9,000) + 11.0 = 11.9 ppg
FCP = 500 x (11.9 ÷11.0) = 541 psi
