ฝึกพูดภาษาอังกฤษด้วยเทคนิค Shadowing จากวิดีโอ: Petroleum - 06 - Drilling Fluid Laboratory

welcome to the drilling and fluids lab

so this lab is meant for studying properties of fluids before

we go into the lab we need to see all the signs

and what they are meaning so our safety is first in this lab

so before getting to this lab you need to have protective gloves you need to have safety glasses

and no food or cell phone

or headphones are allowed inside this lab this is the safety information card approved by the safety department

but university so here you'll find the contact person in case you need anything any question

or any problem inside the lab these are the people

that you need to contact also here you see the chemical hazards

so we can see in this lab we have flammable material we have gas cylinders we have oxidizers

and we have waste chemicals so this will give me an idea on what I have

so we can see here that safety glasses safety gloves

and some protocol is required so this is the requirement this lab everything is described here

so students are advised to read this sheet before going into

the lab we have our gloves on our glasses on then we can go inside the lab so the safety

so as you can see here we have our emergency evacuation

plan we tell our students this is the emergency plan at the first session

when we have a safety introduction session before any lab we

do it each semester we give them this introduction session

so we tell them how to read these maps

so you are here

and you can know where our exits you can see where are some fire extinguishers

so for example here we have our fire extinguisher you can see date on it

when it was last inspected it was on 11 23 2020

and the initial of the person

and the contact number you can just break the glass

and pull the handle for firmly

and then you'll get access to it also we have our first aid

and safety kit which is filled it has all material in it

necessary also we have our safety glasses to provide for students who doesn't have any

and also we have gloves for them

and we always tell them to keep the area clean

and be their own housekeeper in the lab so students

when they leave the lab they need to clean it then

with safety also this equipment here is whenever you have any chemical

that touches your body touches your head or touches your eyes So you can use this equipment.

So this one is for the eyes and for the head

Cleaning and this equipment here is To shower when you have chemicals over your body.

You just push it and the water will come to clean Also students they need to follow these yellow lines,

so they are not allowed Pass these lines

so only authorized personnel can step in these spots

that they are marked in yellow

and you can see for example we have our air bottles

they are firmly secured in the appropriate place approved by the University

and University safety department needs to approve these places

because as you can see we have flammable gases

so they need to be firmly and continuously we keep checking

that they are in the same place students

when they coming to the lab they can either leave their bags

and their school bags in the classrooms or they can put them on this table or under this table.

Once we make sure that all the safety measures are followed now weak students can start doing their experiments.

For example here as you can see

so these are green fluid measurement equipments we have some mixers

and when we are dealing with mixers

so we are expecting maybe some fluid can just come out from this cap

so this is why safety glasses are very important to wear

when you are doing such experiments so these are fluid viscosity viscometers

and rheometers so we can measure the viscosity

and the rheological properties of your mat so this is our bentonite clay

that we keep it in a secure place and it should have The label on it we keep in secure places.

We open it today just for demonstration purposes.

So we make the mixture and then we keep the cap in the same place, out of reach of everyone.

We have also some other equipment stored here.

As you can see, these are marsh funnels to measure viscosity in the field.

This is for measuring the density of fluids.

Ok, so this will help me to fill this cap with drilling mud

and then I can measure how much pound per gallon of

fluid I have then moving to this station here we are still drilling fluids

so this equipment it's hot so we advise students to use it carefully

so there is a manual and either because the heat won't be from outside

but if you are dealing with the inside equipment you need to have some proper gloves to operate this equipment

when you are dealing with high temperature.

And this equipment helps to measure the filtration of the mat.

These are some digital for resistivity meters for the fluid.

This is a wittability test apparatus and this is an oil fluoroscope

that allows me to tell if I have oil left in my sample or not after I clean it.

Moving to this part of equipment here, we can see that also we have some bottles

and they are well secured in place okay some gases are flammable here okay

so for example this gas is non -flammable nitrogen

and this one here i can see the level on the side

so it's also non -flammable okay

so these nitrogen are used for the gas premier meter and gas porosimeter to measure permeability and porosity of a rock sample.

Coming to this part here, we have our sand shaker.

We have our material safety data sheet for all the equipment.

We have it here so students can go and consult it at any time.

This one here generates a lot of noise.

Some students are advised to put some plaques in their ears.

We put the sand and then it will separate it in different meshes to know the size distribution of the sand.

This is a high pressure machine too, so we need to deal with it carefully.

Glasses and gloves are very important when operating this equipment.

This is the saturation machine where you will saturate your core with oil.

Now if you want to clean the core, as you can see we have this deep venting machine this

is the dean star apparatus as you can see there is this screen and it's always down

because we are dealing with some tutorial chemicals and we don't want students

when they are dealing with this equipment to have to inhale the gases

that come out from this equipment this is why we have

this vent coming up you can see from the top you need to activate it

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.
