Q1) IF we found that leak off test is not ok, then whats next
step
Ans 1) If Leak Off Test is not ok, this means cementing is not
proper atcasing shoe. You will have to go for cement repair. This
can be done bycement squeez/plug job.
Q2) IF we are running two mud pump at same spm, but spm of one
mudpump is not remaining stable at same spm, what can be the
reason?
Ans 2) A very good question. Fluctuation or instability in pump
SPM cantell you a lot about pump condition. Timely detection and
fittingcorrective action can save you rig time and money. Now
coming to yourquestion (actually I should dedicate a complete post
for this, anyways inshort)unstable pump SPM, fluctuations of pump
SPM can be of twotypes. First, rapid fluctuations and second, slow
and gradual fluctuations.
Rapid Fluctuations: These are mainly due to mechanical problems
whichcan be, worn out valve ring, valve, valve seat, piston ring
and in worst caseworn out wear plate and liner. You should stop the
pump immediatelyand make a check for the things as mentioned in
order. And if there areany indications of pump taking air then you
should check the mudstrainer in suction line.
Gradual Fluctuations: These are mainly due to electrical and
downholeproblems. There may be problem in SCR, Motor Field or you
are runningnear the load limit. Downhole problem like improper hole
cleaning canalso cause the SPM or pressure fluctuations. For
electrical problemscheck the concerned electrical devices and for
hole cleaning problempump a lo-hi pill (low viscous mud followed by
high viscous mud) andresume drilling after surface to bit time.
Q3) In question 18 on your
posthttp://www.knowenergysolutions.com/2012/03/iwcf-well-control-principles-and-practices-questionsAccording
to the formula given:13 x 0.052 x 0.0080 / (0.0744-0.0080) =
0.08144Now, 0.08144 X 15stnds X 88ft. = 107.508 pYes, you got it
right.
Q4) What is the main factor that determines the rate of build-up
tostabilized SIDPP & SICPP once the well is shut-in?a) Friction
lossesb)Gas migrationc) Permeability
Can someone plz answer and explain
Ans) For IWCF answer should be permeability because he is asking
aboutinitial pressure stablization (when well is just shut in)
afterwards it wouldbe due to gas migration. So if it shows up in
exam mark permeability ascorrect answer as in IWCF answer key they
use permeability as correctanswer.
Q5) One more practice question : Which of the following
parametersmight be affected by permeability of formation (select
three answers)?a)SICPb)Bottom hole pressurec) SIDPP

d)The time taken to stabilise the shut in pressures.e)Volume of
influx
Answer : a,d,e
Q6) Select the good operating practices from the list (THREE)
while drillingtop hole section.a) Maintain as high overbalance as
possible.b) Maintain high drilling ratec) Maintain mud density as
low as possible.d) Continue to circulate when picking up for
connection.e) Circulate at maximum rate to create highest possible
ECD.f) Control drilling rate to avoid overloading the annulus with
cuttings.
Answer 6)I think answers are c,d,f because while drilling in top
hole section :formation is weak so we have to keep mud density as
low as possible,chances of shallow gas are there so continue to
circulate when picking upfor connection, controlling drilling rate
to avoid overloading of annuluswith cuttings.
Q 7) Vertical well is drilled to 9000 ft. with 11.7 ppg mud.Pump
speed: 70 spm.Pressure loss in surface equip.= 140 psi; press. loss
in drill string = 800psi;press. loss in annulus = 100 psi; pressure
loss at bit nozzle = 1400psi.
a) Calculate BHP when mud is circulated at 70 SPM?b) Calculate
eqvlt circulating density.
BHP= hydrostatic pressure + annular losses= 0.052x 900011.7 +
100= 5575.6 psiECD = APL/(.052*TVD) + mud wt= 100/(.052*9000) +
11.7= 11.913
Q 8) When circulating out a kick in a deep well with a deep set
casingshoe, the choke pressure approached MAASP while the influx is
still inopen hole. What is the most important action to take?
Ans 8) You have to bleed through choke. SO that surface pressure
goesbelow MAASP and ZUBIN can you like this website on facebook and
askyour friends interested in IWCF to share their doubts so that we
cancreate a group of interested people in IWCF field.
In instrumentation section there will be questions on BOPs, MGS,
InsideBOp, FOSV, Rated working pressure,koomey control unit and may
be 1-2question on accumalator bottles. It will take us time to
upload questionson instrumentation section but if you have any
query you can post it herewe will try our best to solve your
queries.
Q 10) All influx will be displaced from the hole at a pump
rateconsiderably slower than that used while drilling. Select the
correctreasons for this from the list below:
One of the options is To have minimum pressure being exerted on
theopen hole.I think it will be one of the correct reasons, since
slower pump rate meansless annular pressure losses and hence less
BHP. Is that correct?
Ans10) Yes that is correct logic.!
Q 11) While circulating out a kick, the pump speed is increased
keepingSIDPP constant. What will happen to the BHP.a) Increaseb)
Decreasec) Remains Same(Plz explain the reason).
Ans 10) According to me it should remain same as BHP = SIDPP

hydrostatic head of mud in string.As SIDPP is constant and IN
iwcf we assume mud remains uniform instring so BHP should remain
constant.
people who asked question : Exactly what I thought. However
theTransocean Q&A from where I got this question says it will
DECREASE. Icannot understand how
Q11) A kick is being circulated out at 35 SPM, SIDP is 650 psi,
SICP is 1050psi. What would happen to BHP if pump is slowed down

Q12) One more gud question : Where is the mud loss first noticed
duringthe time of drilling?a) on the mud pressure gaugeb) on the
return flow meter.c)In the mud pits P.V.T(Pit volume totalizer)d)
From the loggers chart.
Ans) on the return flow meter because it will tell instant
change in themud volume.
Q13) Which of the following equipment may warn of increase
information pressure while drilling overbalance? (3 ANSWERS)a) ROP
meterb) Pump pressure guagec) Flow line temp guaged)SPM countere)
Gas Detectorf) Return flow meter
I think c,e,f. Plz confirm.
Ans13) It is a) c) e) Return flow meter is a positive kick
sign.See thedifference between early warning sign and positive kick
signs write if youdont get any material on them I will write more
about it.
Your Diagnosis of problems are correctProblem 1 : Nozzle
plugging Symptoms : D/pipe Pr.: Increasing, Casingpressure
:ConstantProblem 2 : Choke plugged : D/ pipe pr.: Increses, Casing
pressure:IncreasesProblem 3 : Choke Washout : D/ Pipe Pr :
Decreases, Casing Pr :DecreasesProblem 4 : Pump Failure : D/ Pipe
Pr : Decreases, Casing Pr : Decreases (No sound of pump in
simulator)
As while killing nozzle is plugged in question 1 so bottom hole
pressurewill remain same because we will calculate from annulus
side becauseafter nozzle plugging We hold Casing Pressure Constant
and then bringpump down and Close Choke.Identify the problem and
bring SIDP atoriginal value. Keeping casing Pr. Constant bring pump
to kill speed.Maintain new drill pipe pressure constant. Also
change in reading in drillpipe pressure gauge is due to nozzle
plugging ( As more pressure is lost innozzle due to plugging) and
as annular friction losses are same BHP willremain same,
As choke is plugged in case 2 : Action to be taken are :Stop
pump immediately and close HCR.Identify the problem bring the SIDP
at original value.Line up alternate choke and HCR.Keeping casing
Pr. Constant bring pump to kill speed.Maintain Drill pipe pressure
constant.Because of choke plugging annular friction losses have
increased by 200psi in case 2 so BHP should increase by 200 psi.We
are working on a kill sheet application which will help you in
practicing

kill sheet and also will post some questions on instrumentation
section. Inthe meantime you can focus on BOP figures, koomey
control unitfigures,pipe ram figure according to course.
Q14) Stack config: (from top to bottom) Annular=>> 5 Pipe
ram=>>Blind/Shear=>> 3 1/2 Pipe ram =>> Drilling
spool.With the drill string hung-off on the 31/2 rams, can the
annular berepaired?Plz Explain hung off.Reply
q15) With the drill string hung-off on the 31/2 rams, can the
outerchoke line valve be repaired?Yes/No
q16) With the drill string hung-off on the 5 rams, can the
annular berepaired?yes/no
Ans 14) no as drilling spool is below 3 1/2 ram outer choke line
valve cantbe repaired.
Ans 15) yes as it is above on 5 RAn from where drill string is
hung offannular can be repaired.
Ans 16) hung off means 3 1/2 inch ram is closed and stringis
hung on thisram BOP. so joints below it cant be repaired.Annular
can be repaired.Modify message
Steve says:
Ans 11. BHP = hydrostatic head of mud + pump pressure
drillpipefriction. Drillpipe friction INCREASES with pump rate.
Therefore tomaintain the same BHP when the pump rate is increased
the drillpipepressure has to increase.

how was qestion #33 solved?
Ehis says:
sorry I mearnt how was question #32 solved not #33
admin says:
Since annulus is filled with original mud so change in BHP is
zero. now ifyou want to calculate from string side you will
calcluate length of slug volumeand original mud column in string by
applying U-tube principle at bottom. Butif you can get it directly
from annulus why to apply it from string side.

if I have a 13.6 ppg mud going in and a 13.2 coming out after
adding 220sx of 50 # sx of bar why wont my weight increase

If I wanted to do classs online or from home how do I do that.
Im evenwilling to go to wherever the teacher is and put myself in a
hotel and paythem two teach me a few hrs each day and give me tests
I really want tosucceed in my field I am a mud engineer but I need
basic instructionsplease call me or email me 315 836 6313

hi, could you please check this spreadsheet for Q44 and let me
knowwhats wrong, because i got 41 stands instead of 39 (answer)

admin says:
Rather than using spreadsheet calculate by using formula as
spreadsheetmay be prepared according to different set of
values.
alvis says:
what is the formula for Q55?
admin says:
Pump pressure is directly proportional to mud weight and square
of pumpSPM . Here pump spm is constant 30 so New pressure = (New
mudweight*old Pump pressure)/old mud weight

steven aitken says:
Can you please explain on question 16 why a small influx will
increase thechances of exceeding MAASP???????
admin says:
Sorry answer would be large influx will increase the chances of
exceeding theMAASP. We have rectified answers.
HERISH says:
please can some one answer me?
while gas migrate up the well after a period time of shut in .
in order tokeep BHP constant why should i depend on SIDPP constant
to migratethe gas, before i begin to kill the well ..
admin says:
As There is homegenous column of mud in string. It is assumed
that influxenters annulus at is least resistance path. So SIDPP +
Hydrostatic Pr of MUDin string= Bottom Hole Pressure.
