Shadowing Practice: Petroleum - 06 - Drilling Fluid Laboratory - Learn English Speaking with Video
Creating lesson...
1
welcome to the drilling and fluids lab
2
so this lab is meant for studying properties of fluids before
3
we go into the lab we need to see all the signs
4
and what they are meaning so our safety is first in this lab
5
so before getting to this lab you need to have protective gloves you need to have safety glasses
6
and no food or cell phone
7
or headphones are allowed inside this lab this is the safety information card approved by the safety department
8
but university so here you'll find the contact person in case you need anything any question
9
or any problem inside the lab these are the people
10
that you need to contact also here you see the chemical hazards
11
so we can see in this lab we have flammable material we have gas cylinders we have oxidizers
12
and we have waste chemicals so this will give me an idea on what I have
13
so we can see here that safety glasses safety gloves
14
and some protocol is required so this is the requirement this lab everything is described here
15
so students are advised to read this sheet before going into
16
the lab we have our gloves on our glasses on then we can go inside the lab so the safety
17
so as you can see here we have our emergency evacuation
18
plan we tell our students this is the emergency plan at the first session
19
when we have a safety introduction session before any lab we
20
do it each semester we give them this introduction session
21
so we tell them how to read these maps
22
so you are here
23
and you can know where our exits you can see where are some fire extinguishers
24
so for example here we have our fire extinguisher you can see date on it
25
when it was last inspected it was on 11 23 2020
26
and the initial of the person
27
and the contact number you can just break the glass
28
and pull the handle for firmly
29
and then you'll get access to it also we have our first aid
30
and safety kit which is filled it has all material in it
31
necessary also we have our safety glasses to provide for students who doesn't have any
32
and also we have gloves for them
33
and we always tell them to keep the area clean
34
and be their own housekeeper in the lab so students
35
when they leave the lab they need to clean it then
36
with safety also this equipment here is whenever you have any chemical
37
that touches your body touches your head or touches your eyes So you can use this equipment.
38
So this one is for the eyes and for the head
39
Cleaning and this equipment here is To shower when you have chemicals over your body.
40
You just push it and the water will come to clean Also students they need to follow these yellow lines,
41
so they are not allowed Pass these lines
42
so only authorized personnel can step in these spots
43
that they are marked in yellow
44
and you can see for example we have our air bottles
45
they are firmly secured in the appropriate place approved by the University
46
and University safety department needs to approve these places
47
because as you can see we have flammable gases
48
so they need to be firmly and continuously we keep checking
49
that they are in the same place students
50
when they coming to the lab they can either leave their bags
51
and their school bags in the classrooms or they can put them on this table or under this table.
52
Once we make sure that all the safety measures are followed now weak students can start doing their experiments.
53
For example here as you can see
54
so these are green fluid measurement equipments we have some mixers
55
and when we are dealing with mixers
56
so we are expecting maybe some fluid can just come out from this cap
57
so this is why safety glasses are very important to wear
58
when you are doing such experiments so these are fluid viscosity viscometers
59
and rheometers so we can measure the viscosity
60
and the rheological properties of your mat so this is our bentonite clay
61
that we keep it in a secure place and it should have The label on it we keep in secure places.
62
We open it today just for demonstration purposes.
63
So we make the mixture and then we keep the cap in the same place, out of reach of everyone.
64
We have also some other equipment stored here.
65
As you can see, these are marsh funnels to measure viscosity in the field.
66
This is for measuring the density of fluids.
67
Ok, so this will help me to fill this cap with drilling mud
68
and then I can measure how much pound per gallon of
69
fluid I have then moving to this station here we are still drilling fluids
70
so this equipment it's hot so we advise students to use it carefully
71
so there is a manual and either because the heat won't be from outside
72
but if you are dealing with the inside equipment you need to have some proper gloves to operate this equipment
73
when you are dealing with high temperature.
74
And this equipment helps to measure the filtration of the mat.
75
These are some digital for resistivity meters for the fluid.
76
This is a wittability test apparatus and this is an oil fluoroscope
77
that allows me to tell if I have oil left in my sample or not after I clean it.
78
Moving to this part of equipment here, we can see that also we have some bottles
79
and they are well secured in place okay some gases are flammable here okay
80
so for example this gas is non -flammable nitrogen
81
and this one here i can see the level on the side
82
so it's also non -flammable okay
83
so these nitrogen are used for the gas premier meter and gas porosimeter to measure permeability and porosity of a rock sample.
84
Coming to this part here, we have our sand shaker.
85
We have our material safety data sheet for all the equipment.
86
We have it here so students can go and consult it at any time.
87
This one here generates a lot of noise.
88
Some students are advised to put some plaques in their ears.
89
We put the sand and then it will separate it in different meshes to know the size distribution of the sand.
90
This is a high pressure machine too, so we need to deal with it carefully.
91
Glasses and gloves are very important when operating this equipment.
92
This is the saturation machine where you will saturate your core with oil.
93
Now if you want to clean the core, as you can see we have this deep venting machine this
94
is the dean star apparatus as you can see there is this screen and it's always down
95
because we are dealing with some tutorial chemicals and we don't want students
96
when they are dealing with this equipment to have to inhale the gases
97
that come out from this equipment this is why we have
98
this vent coming up you can see from the top you need to activate it
99
and also we need to keep this door down
100
so the gases doesn't come so you can see here turn on cold water
101
when using mental heater so
102
when we are using the heater we need we need to
103
turn on the cold water slowly lower glass such to maintain fume extraction
104
so slowly there are some extractions the students need to follow carefully on how to operate these doors
105
and how to operate this equipment
106
because it has some chemicals also some chemicals are stored here in the bottom okay
107
and they need to follow the university safety guidelines on how to store the waste of chemicals okay
108
and masks also are required when you are running an experiment here they are not
109
so it depends on what chemical you are using you can put masks
110
when you are using
111
but the van should be working as soon as this starts operating here we have different containers
112
when you want to make any mixture of brine any fluid
113
you have some magnetic stirrer you put your cap with the
114
magnetic stirrer to mix it you have some distant water
115
and different type of containers that you can use them
116
and put the levels on so everything should be leveled so we know
117
what we have so
118
if we find any container that's not labeled in this lab we ask the same time who knows what's
119
that if we don't know to throw it away after we make sure what it is
120
because we cannot keep any container here that has to do it
121
that we don't know what it is it might be toxic so it's very important to know.
122
As you can see here, anything they need to write what kind of fluid they have inside.
123
This is also a gas per meter, so a spare one we have.
124
This is an equipment also that works with pressure bottles.
125
Okay, so this is for capillary pressure measurements.
126
And finally, we have the high sensitivity balances.
127
You can see this, for example, this one, it helps to measure at the order of 0 .0001 gram.
128
So basically, these are the equipments we have in this drilling
129
and fluid lab and always safety is the first measure we have.
130
We provide to fill in gloves and masks,
131
glasses, everything, so we make sure before they come here they are safe because safety is first in our gloves.
132
Thank you.

What is the Shadowing Technique?
Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
