b. Over torqued?
c. Not H2S trimmed?
d. Poor row material quality?
e. Other?
---------------------------------------------
3- You are using the volumetric Method to control a gas influx in a vertical wellbore.when can the maximum casing shoe pressure occur?
A- it stays the same throughout the operation.
B- when the top of the gas is at the casing shoe.
C- when the top of the gas is reaches the surface.
D- at any time.
---------------------------------------------
4- long tooth bits require more hydraulic horsepower than do short tooth bits for the same formation?
A-True 
B- False and why ???
---------------------------------------------
5- While drilling in shale formation no filter cake can be formed?
A-True 
B- False and why ???
---------------------------------------------
6- One of the most important rules in well control is to ......?
---------------------------------------------
7- What is the preferable BOP test fluid and why?
---------------------------------------------
-----------------------------------------------
8- These 3 wells have been drilled with a mud of specific gravity of 1.25 gr/cm3 in which well A,B or C will the highest hydrostatic bottom hole pressure be recorded.

a. Well A
b. Well B
c. Well C
d. All three will have equal bottom hole pressure
---------------------------------------------
9- What is one of the first things a driller checks before getting on the brake?
---------------------------------------------
10- What the Relation between Mud weight and MPD ?
----------------------------------------------
-----------------------------------------------
11- While drilling 8 1/2" hole ( hard formation & long section ) , client decided to POOH for test BOP coz it exceeded 14 days, Wellhead is Vetco gray type and the AD bring test plug FMC type by mistake then they run with it, Test plug stuck in wellhead, they take overpull can't release it..........How we can solve these problem?????.

Explain in details....... It's real situation happened before in one rig.
-----------------------------------------------
12- What are some precautions that can help prevent differential stuck pipe?
-----------------------------------------------

-------------------------------------------------
13- You are currently circulating a gas influx out of the well the driller method, What should happen to active pit level volume during the circulation?
------------------------------------------------
14- If a shallow gas flow is encountered while drilling the surface hole, which of the following actions should be performed at the same time as activating the diverter? 
A, Direct flow through the mud gas separator
B, maintain constant pump rate
C, increase pump rate
D, decrease pump rate
-------------------------------------------------
15- What are factors affect the penetration rates?
a) …………………
b) …………………
c) …………………
d) …………………
-------------------------------------------------
16- Why should the well be closed in quickly after a kick has been detected?
A- Minimize the influx into the well bore
B- Minimize the SICP
C- Minimize the bottom hole press.
D- Minimize the casing shoe pressure.
--------------------------------------------------
17- What material is used to reduce torque at the bit by reducing the coefficient of friction?
--------------------------------------------------
18- What two components comprise a diamond bits TFA ?
--------------------------------------------------
19- What is the most important steps in blowout prevention once
the awarning sign has been detected:
A- Start circulation with per circulated rate and kill the well barite
B- Shut the blow out preventer
C- Pull to the shoe quickly
D- Call the tool pusher and company man
E- Close the well in properly
------------------------------------------------------
20- If the formation pressure gradient increase from 0.60 psi/ft at 1200
ft to 0.62 psi/ft at 12700 ft mud weight is 12 ppg through the interval the
A- overbalance increase by about 288 psi
B- overbalance increase constant since mud weight not changed-
C- overbalance is reduced by 51 psi
D- overbalance is reduced by 237 psi
