Seadrill is an oil drilling company with over 5,000 employees in hundreds of roles to suit different careers. It prioritizes rewarding employees with competitive packages, work-life balance, and training. The document then details the multi-step process for drilling an oil well, including hiring geologists to analyze the area, marking the drilling location, obtaining permits, setting up equipment and infrastructure, and drilling the main hole to extract oil samples. It recommends safety meetings, limiting personnel during operations, training centers, and implementing safety and environmental policies.

In the course of time, man has been continuously
researching and exploiting the different energy sources that
can be found within the earth's crust, such resources can
be renewable and non-renewable. The exploitation of
different energy resources must be rationally carried out by
man, for the welfare of his community and that of his
environment or environment.
It is the field activity that consists of moving a drill, dressing
the equipment and connecting a wick or a string of steel
pipe to penetrate the formations until building a hole; This
is conditioned and ends up turning it into an oil well.
The following steps are the most fundamental for drilling an
oil well:
1. Hire geologists to analyze the
characteristics of the area and see if
oil is likely.
• Geologists will analyze the
characteristics of the area's surface,
terrain, stones and soil types, as well
as the Earth's magnetic and
gravitational fields.
• There are several methods used to
carry out a seismic study, in which
the shock waves are sent through
the ground layers in the subsoil for
later analysis.
• Hydrocarbons can be detected
using "noses" or trackers.
2. Mark the area for drilling.
If the area is in the water, place
buoys around. Use GPS
coordinates to mark the
designated points and use them
at the time of drilling.
3. Perform the necessary legal steps.
Obtain permits, legal agreements,
titles, etc. necessary to be able to
drill the area. Measure the impact
that drilling will have on the
environment.
4. Clean and level the
designated area.
5. Make sure there are nearby
water sources, as it will be
necessary for drilling.
If there are no natural water
sources, you will need to drill a
water well.

3. 6. Dig a reserve hole and
line it up with plastic.
This will serve to place
the rocks and mud
resulting from the
drilling.
• Rocks and mud should
be removed outside the
area if drilling occurs in a
sensitive ecological area.
7. Dig a rectangular hole, close
to the drilling point, to be the
workspace for the drilling
equipment.
Dig the holes that are necessary
to store the equipment.

preferido para explorar y producir hidrocarburos.
After locating the hole there are two methods that
are performed to extract the oil, which are the
following:
1. Method
Drilling of the main hole
1. Use a well drilling truck to make a
starter hole that is less deep and
wider than the future main hole.
Cover the hole with a conductive
tube
2. Drill the main hole with an oil
rig, but stop before reaching the
location of the oil trap. Set the
mouth, neck and drill pipe in the
hole, and fix the Kelly drill tube
and the turntable (the system that
pumps the mud).
Start drilling and remove the rocks from the hole.
• You can drill hundreds or thousands of meters deep
before reaching the oil trap. As you drill deeper, you
will need more pipes and linings.
3. Insert the tube cover
into the hole.

4. 4. Place cement in the hole to
prevent collapses. Pumps cement
and drains the mud through the
pipe with a cement grout and a
bottom plug. The cement will
move through the lining tube and
fill the area between the outside
of this and the hole. Let the
cement harden.
5. Stop drilling when rock
debris shows signs of tar
sand in the reservoir rock.
6. Take rock samples,
measure the pressure and
lower the gas sensors in the
hole to determine if the
reservoir has already been
reached. Continue drilling if
you haven't done it yet.
2 Method
Measures to be taken once the site is reached
1. Lower an oil drilling
gun to drill holes in the
casing tube.
2. Place the pipe inside
the hole so that oil and
gas rise through it.
3. Seal the outside of the
pipe with a "packer".
4. Control the flow of oil.
Connect a structure with
multiple valves (called
"Christmas tree") at the
top of the pipe
5. Remove the
platform when oil
begins to flow.

5. 6. Install a pump in
the wellhead.
RECOMMENDATIONS
- It is essential to hold work meetings with the
purpose of delegating responsibilities in emergency
situations or in the event that an influx is detected in
the well
- In the work area, only the people who will carry out
the operation of the well control must be in order to
minimize personnel risks
- It has training centers designed for the training of
drilling rigs, for a better compression of the
phenomena that occur at the bottom of the well. As
well as training drilling floor personnel, to perform
their functions in the event of an influx or lack of
control
- implement and disseminate the company's
industrial safety and environmental protection
policies
