Geologists and geophysicists have agreed on the existence of a "prospect", a potential field. In order to find out if hydrocarbons are indeed trapped in the reservoir rock, we must drill to hit them. Bearing in mind the knowledge acquired about the substratum and the topography of the land, the best position for the installation of the drilling equipment is determined. Generally it is vertically above the point of maximum thickness of the geological layer suspected of containing hydrocarbons. The drillers then make a hole in conditions that are sometimes difficult.
Of small diameter (from 20 to 50 cm) this hole will generally go down to a depth of between 2000 and 4000 meters. Exceptionally, certain wells exceed 6000 m. One of them has even exceeded 11 000 m! Certain fields can be buried at a depth equivalent to the height of 12 Eiffel Towers ... The derrick is the visible part of the drilling rig. It is a metal tower several tens of meters high. It is used to vertically introduce the drill strings down the hole. These drill strings are made up of metallic tubes screwed end to end. They transmit a rotating movement (rotary drilling) to the drilling tool (the drill bit) and help circulate a liquid called "mud" (because of its appearance) down to the bottom of the well.
The drilling rig works like an enormous electric hand-drill of which the derrick would be the body, the drill strings the drive and the drilling tool the drill bit. The most usual tool is an assembly of three cones -- from which comes the name "tri cone" -- in very hard steel, which crushes the rock. Sometimes when the rock being drilled is very resistant, a single block tool encrusted with diamonds is used. This wears down the rock by abrasion. Through the drill pipes, at the extremity of which the drill bit rotates, a special mud is injected, which the mud engineer prepares and controls. This mud cools the drill bit and consolidates the sides of the borehole. Moreover it avoids a gushing of oil, gas or water from the layer being drilled, by equilibrating the pressure.
Finally, the mud cleans the bottom of the well. As it makes its way along the pipes, it carries the rock fragments (cuttings) to the surface. The geologist examines these cuttings to discover the characteristics of the rocks being drilled and to detect eventual shows of hydrocarbons. The cuttings, fragments of rock crushed by the drill bit, are brought back up to the surface by the mud. To obtain information on the characteristics of the rock being drilled, a core sample is taken. The drill bit is replaced by a hollow tool called a core sampler, which extracts a cylindrical sample of several meters of rock. This core supplies data on the nature of the rock, the inclination of the layers, the structure, permeability, porosity, fluid content and the fossils present. After having drilled a few hundred of meters, the explorers and drillers undertake measurements down the hole called loggings, by lowering electronic tools into the well to measure the physical parameters of the rock being drilled.
These measures validate, or invalidate, or make more precise the hypotheses put forward earlier about the rocks and the fluids that they contain. The log engineer is responsible for the analysis of the results of the various loggings. The sides of the well are then reinforced by steel tubes screwed end to end. These tubes (called casings) are cemented into the ground. They isolate the various layers encountered. When hydrocarbons are found, and if the pressure is sufficient to allow them come to the surface naturally, the drillers do a flow check. The oil is allowed to come to the surface during several hours or several days through a calibrated hole.
The quantity recovered is measured, as are the changes in pressure at the bottom of the well. In this way, a little more knowledge is gained about the probable productivity of the field. If the field seems promising, the exploration team ends the first discovery well and goes on to drill a second, even several others, several hundred or thousand meters further away. In this way, the exploration team is able to refine its knowledge about the characteristics of the field. The decision to stop drilling is made only when all these appraisal wells have provided sufficient information either to give up the exploration or to envisage future production.

I wish I could get this type of lesson everyday from you, you have made oil and gas drilling more understandable to me in your explanation
Really good, demystifies the process for the uninitiated.
thank you keep uploading more it helps my studies
I like this video. point to point explanation of drilling.
Neat Animations!!! Definitely makes it easy to follow along and they are very informative...
VERY GOOD EFFORT--THANKS FOR UPLIFTING SUCH TROUBLES FOR OUR LEARNING
Petroleum Engineering Zero to Hero: this channel has videos about petroleum and oil and gas industry
thank you
Thanks. Quite didactic. I learned a lot.
Clear and easy to understand. Good video
thanks! very informative!
how do the floating derricks account for waves? looks like only 2 versions are propped up on a structure. just seems like a big wave would break the driling pipes by shifting the derrick a bit too far or at all.
Very clear and precise explanation
thanks it's really useful :)
watching this now because of deepwater horizon.... very enlightening!
Well done....Thank you
oh so this is how they work thanks
VERY GOOD
Here learning more about oil drilling, waiting for news this weekend from 88 Energy Limited (EEENF stock) drilling in Alaska.
Aaaah, at last a clip from the 21st century. One that uses the metric measurement system. Thanks. I like.
And you are able to correctly pronounce the word "tubes". Now I know what these people of lower intellect, in the other clips, talk about when they refer to something like "toobs".
Great clip. Excellent explanation. Very informative.
nice video on usa oil & gas ..
good presentation and animation for oil n gas
This video is just awes❤me...
Thank you!
welcome:)
Excellent
thanks
very educative...well explained
pretty good
nice understandable
Best video ☺
Very nice and informative
Thank You Sir .... 🙂
Thanks sir
oyerior Cyril odianosen
I like this videos in the area of explanation.
Good
Excellent vedio
animations are good. thanks for sharing.
you're welcome :)
Oil & Gas Videos
I'm here after watching Deepwater Horizon ^o^
Ha - I literally just paused a documentary on the Deepwater Horizon to watch this.
nice video
So how many stages of drilling are there?
Super...good...
Are they anchored just like a ship or boat would be?
This is good the Well Completion
when we drill for Oil or Gas, large Hole are created in the subsoil and in some cases the well is filled with water, it makes no sense the subsoil becomes unstable and a sink hole is created which is not without reason we use Oil in Oil Pressure systems and not water.
Tq so much bayya
it's really fascinating!
Kimberly gibson Hi
How to do these type animations...i have somw concept to present to my manager...wat are the softwares...any suggestions..
nice
Very informative video. Now I know better what's going on under the well. And how geophysicists view the well. I also learned how many types of wells are divided into those in the ocean. And the most interesting thing is that the depth of the well can reach more than 11000m.
Very interesting video!
Esther Abrams Hi
Sexy
Anyone in (ukog) uk OIL AND GAS.Wow, massive oil find Nr Gatwick Airport.
Everyone Social Media talking about them.
Dope
I like the work, can someone Lean it manual
2000, 4000, 6000, 11,000 feet shows just how much sediment was washed off Earth during the Flood 4,350 years ago.
proud to be an petroleum engineer
Guys plz do video about salary after tax
good badyyy
Hey greetings i just want to know about the short term study in gasoline sector can you please suggestion me different and particular courses that i can do in india and can make a line in gasoline sector please.
if interested for oil and gas drilling sector see below two online courses.

I read alot of comments. I'm looking for a visual aide to explain this to my little brother. This isn't bad but not what I'm looking for. I've worked a telescopic single, a tele-double, and a jackknife double, for years. There was a shitload of stuff they glossed over about the day to day, from start to finish and even who mixes the mud was wrong. If any green-horns or anyone in general has a question, just ask me and I'll try and help you out, especially if you're looking to get into the Oilpatch.
Who mixes the mud then?
oil prices got me searching …
Kerennn🤩
Good for children
well well well what do we have here
i want the compelete course
do u have any vids about tools manufacturing ??

do you you have a russian version?
Unfortunately, no. You can display video subtitles (or download them using any online tool) and translate them using google translation. Hope this helps.
Does this land exploration applies also to off-shore exploration? (Urgent question)
In general, the equipment used in both offshore and onshore drilling are not much different. Both methods require tools like exploratory equipment, waste-water/oil separators, pumps, pipelines and storage tanks.
However, there are some key differences between offshore and onshore drilling equipment as well, specifically in the structure of the drilling rig itself. Onshore drilling rigs are the more classic drilling equipment and come in different sizes and strengths. They are generally classified by their maximum drilling depth and their mobility. Conventional land rigs cannot be moved as a whole unit and are typically used in the petroleum industry while mobile rigs are drilling systems that are mounted on wheeled trucks and come in two different types, jackknife and portable mast.
Thanks for answering me immediately!!! :)
👍👍
11000 meters, holy shit! What were they drilling for...magma?!
Diameter of the Earth is 12,742 km just 11 km of them never lead to magma :)
The worlds longest drilled oil well is BD-04-A, with a total length of 40,320 ft (12.3 km) MDRT. It was completed in May 2008 by Maersk Oil Qatar and Qatar Petroleum, in the Al-Shaheen offshore oil field off the coast of Qatar. The well includes a horizontal section measuring 35,770 ft.
Such a small diameter (from 20 to 50 cm) with a length of 11 km in comparison with the surface area of the Earth which is 510.1 million km² and a diameter of 12,742 km, will never crack the Earth :)
yea...36 grand & some change to boot with.
Trapped in the reservoir rock
We must drill to hit them
Derrick- is the visible part of the drilling rig
Drill strings
Gushing of oil
Equilibrating
Core sampling
Permeability

Refine
Geologists, Exploration team agree on the place where drilling will be conducted.
To find out whether hydrocarbons are indeed Trapped in the reservoir rock we must drill to hit them. After, a hole of small diameter (20-50cm) is made.
The decision to stop drilling is made only when these appraisal wells have provided sufficient information either to give up the exploration or to envisage future production.
I am an chemical engineer. I want to start my career in onshore fields, can anybody help?
you can enter as mud engineer into oil and gas drilling sector
Holy shit
😭😭😭
This was completely inaccurate smh
thanks
