General Instructions:
This is a closed book exam.
Besides you calculator, electronic devices of any kind (mobile phones, iPods, pocket PC’s, etc) are
prohibited.
Do not detach any sheet from your exam.
Questions on the problems:
You must show your calculations and box the final answer to receive full credit for your work.
Use only the space allotted at the respective page to solve these questions.
If you need extra space to develop any question, you can use the final page to do so. However,
the content on that page will not be graded.
Failure to indicate the units in your calculation will result in losing points.
Make and state clearly any assumptions that you believe are necessary.

Questions 1: Mark A – True or B - False, for the following statements:
(20 points – 2 each)
Question A(True) B(False)
1.1 The well control system allows you: to close the well at surface, to move
the drill string under existing pressure in the well and to divert flow away
from rig personnel and equipment.
X
1.2 If we are tripping out of the hole and the actual mud volume needed to fill
up the hole is greater than calculated, this is a positive indicator of a kick in
progress.
X
1.3 MWD specifically refers to measurements taken downhole in real time
using devices located on BHA (Bottom Hole Assembly). This technique is
typically used for higher cost-directional wells.
X
1.4 Motion Compensating System is used to avoid that horizontal movement of
an offshore floating rigs gets transferred to the drill string, allowing the
application of constant weight on bit.
X
1.5 When the drawworks drum is almost empty of drilling line, the torque
developed at the drawwork can be up to 20% greater than when it is
completely full of drilling line.
X
1.6 The Drawworks of a drilling Rig is part of the hoisting system. X
1.7 The ECD relates to pressure losses in the drill string. X
1.8 The LMRP of a SS or DS should be disconnected in case the rig is drifting. X
1.9 Among the most important functions for a drilling riser (used when drilling
in offshore), we must include: to connect the subsea BOP to the floating
drilling unit, to allow full circulation of the drilling mud and to serve as
support for auxiliary lines (choke, kill lines, umbilical).
X
1.10 The average length of a DC is 30 meters. X
