Underbalanced Drilling: 2018 #68

Problem 68: The following statement about underbalanced drilling most FALSE is: 

(A) During the workover...a suspension plug is installed...after the well is lubricated to kill fluid. 
(B) Advantages include eliminating differential sticking & faster ROP. 
(C) Disadvantages include possible increased torque & drag & poor MWD compatibility. 
(D) Flow control, not pressure control, is the main well control issue.

This problem is referenced on GB 2 DRL 11 or on HS2 P556, P522, P522, and P520. Note the Guidebook should have the suspension plug step listed before the kill fluid; please pencil this in (fixed in V3).

Note these type of questions could come from any direction; for more detailed information on the read HS P556 (it's quite interesting). Note there are a million ways this problem can be worded; the Guidebook can only introduce and guide you to the subject. You may need to dig deeper using the listed references; this mostly depends on your experience.
