How Do Oil Pumpjacks Work?

- Thanks for watching! This video takes a look at pumpjacks, colloquially referred to as Oil Derricks and oil horses. “Oil derricks” themselves are the hoisting structure used for drilling. After the oil well is tapped, then these pump jacks are used to extract the oil.
For anyone who has ever driven through the southern United States or other oil-rich areas, you likely are familiar with the sight of oil derricks. These metal moving hammer-like structures work to extract oil from underground - often in the middle of nowhere. All this probably leaves you wondering, how do they actually work and what happens to the oil once it's taken from below ground?
Called pumpjacks, oil horses, oil derricks, these large metal structures are crucial to supplying the US and ultimately the world with its oil needs. They function as traditional sucker rod pumps, known more technically as reciprocating piston pumps, and are made up of 5 parts: the prime mover, the crank, the samson posts, the walking beam, and the sucker rod.

No no yes oil 🛢️ pamp for many

The reason why oil is such a good energy fs because of its energy density. What is energy density? Energy density is the amount of energy chemical or nuclear reaction (mega joule/kilogram mass) could create (we will not be talking about energy efficiency so don't need to mention it). Fossil fuel has comparably high energy density when compare to other common energy source like lithium battery. It is very useful for airline since it can't fly if the plane is stuffed full of batteries.
Here is a video about the possibility of electric plane.

What's incredible is that in less than 100 years we went from traveling with horses to landing on the moon but the oil pumps are pretty much the same as back in the days
The only land you stepped on is that of earth :3
@@miloudbouchefra200 missed your Thorazine today?
I usually say the same thing about those who actually believe that someone reaxhed the moon lol
Just review the video and explain to me the source of the wind to which the flag was flapping.
@@miloudbouchefra200 you are a pure idiot. There's no wind, the "flapping" has been already explained many times by many people and was easily reproduced in a vacuum chamber by the Mythbusters. But when you are a deluded paranoid schizophrenic, you keep asking the same stupid questions that have already been answered and come up with the same conspiratard garbage that has been already debunked many times. Unfortunately, when faced with proof, your flat brains reset and go back to the last safe state, hence the repeating of the crap inside.
One interesting thing to note is that the horsehead has a precision curve that provides a fixed distance between the tangent of the curve and the pivot point of the walking beam (i.e. constant radius). This allows the shaft of the pump to move in a perfect vertical motion.
Orca James knows!
Usually the mechanism that actually pulls it up is cables next to the beam, and not actually grabbing the beam itself, the beam is only being guided by the head.
Cam principle!!!!
First time I ever saw one of these in person, I was traveling either through southern Illinois or into Missouri. Was a real thrill to see these machines that I had only seen in cartoons since I was a kid.
Yeah, in the video he says "next time you drive by one..." 😲 I just searched on this, because you only see them in movies from Hollywood. 😛 Probably wont see one in my whole life.
@@HakanMB These pumps are everywhere in Kansas, Ok, Texas...
And a lot around LA hence why you see them in Hollywood movies!
Same with me 😂

You’ve explained something that I’ve always wondered about. Thanks
You’re welcome! We’ve got a ton of other videos explaining other stuff too🙂
As a former servicing rig and drilling rig rough neck back in the 70s, this brought back memories.
When I became a pumpjack technician, I fell in love with learning about pumpjacks, and down-hole operations. I wish I could have been born years ago to experience it for many more years than I'll likely get to in my life time.
Sir Technician, may I ask why are they never removed? I see many stay without function for years or decades.. Not moving but not removed or moved to another place?
take you odd obsession somewhere
@@Fukallahbecause they're not hurting anyone jackass
@@Fukallah Economics. The cost of disassembling, replacing worn parts and refurbishing others, plus the cost to move it to a new location would be the same as buying a new one. Once an oil field gets pumped out there needs to be enhanced recovery methods employed to recover any remaining oil and it just isn't economical at current prices. So shut the well in and wait a few decades to see if it becomes profitable again.
An old family friend of mine lived way out in the woods of Texas and about a mile down this gravel road at the start of his driveway there were two of these, and one day I walked down there to watch them. It had three massive tanks and one of them happened to be unlocked at the top and the ladder was open so I went up and looked in. Never seen that much oil before but it was still a fun memory as a kid
You better be glad you didn't fall in that. They wouldn't have found you in time.
I don't know if there's any coming out of crude, maybe if you somehow didn't burn your eyes and if they had a ladder you could find in time. Now here's a funny question, since oil is lighter than water, could you even swim in oil?
This is a horrible idea please for the love of God never do this its called a thief hatch at the top of the tank and opening it causes hydrogen sulfide to blow out of the hatch when you pop it open I work on oilfield equipment and I wear an air pack to do this exact thing because being exposed to enough h2s it will knock you down and you will pass out instantly and you will eventually die as you keep being exposed
@@dogge929 no, you fall in a tank your dead 💀 Iv worked in the oil field many years as a crude oil truck driver.
As one of the other commenters pointed out, an "oil derrick" is actually a tower that is set up OVER the well and pumping unit to enable servicing of the well when necessary. For many years, these towers -- similar to the towers used to drill the well in the first place -- were left standing over the well and pumping unit for years; since about 1960, however, they are more commonly folded up on large trucks and driven from well to well, so few if any wells have permanent "derricks" standing over them anymore. The rocking "pumping units," however, are still quite common in oil fields. Otherwise a very good video!
Definitely. When writing this script the terms got interchanged slightly. I tried to change the title as well as make disclaimers about this in the description. I totally understand 🙂✌🏻
This is a pump jack....not a Derrick. The British call them 'nodding donkeys'.
I completely missed that fact lol
im a kid who always goes trucking with my dad so i see these things ALL THE TIME
i knew what they were called and everything but always wondered what happened underground
thanks for the video!
I call it the lil pump
wow

One of the many reasons why I love youtube. I passed by a few of these today on a business trip in Oklahoma and wanted to know how they worked.
I work in the oil field here in texas as a lease operator, i check this units every day. This are called pumping units also known as pumpjacks in the slang language. Derrick is the platform used on drilling rigs and pulling units. And the pumps used in this type of wells do not look like that. Thats more like a pump used in old water wells
jose pena I’ve been trying to get in there for a long while now any advice to getting an oilfield job?
I pump wells also, I cringe every time I hear the word “pump jacks”.
@@czar2074 are you still interested in the oilfields? Are you in Canada or willing to relocate?

Worked with pump jacks for 35 years. Just looking at you title told me all I needed to know about you vid.
Thanks pump and the people that run them!!
They are called Nodding Donkeys in some parts.
Yep!
I grew up in Wilmington, CA which sits on top of a large oil field. These pumps were everywhere, including people's back yards.
That's the only name I've heard besides pumpjack. I'm a Navy brat, so I've lived all over. Weird.
Anyone else here after oil prices hit negative numbers today?
Great video ,good explanation to the main principles of how these oil pumps work!.
I find it interesting!!
Thanks!
Very informative. My Grandpa always called them "a donkey eating hay".
Thanks!
I’ve always wondered... thanks for this!
I love knowing how these machines work and their usefulness to obtain oil
Thank you. I'm 53, but tonight, I learned something new, thanks to your video. :-)
Great video. You got right to the point and explained it clearly.
Thank you-
Just about to take a trip to Southern California, on the way there I tend to see a lot of these things. Now this time I'll know how they work! :)
Orange county in southern California has a lot of pumpjacks.
I remember seein' millions of those things in Long Beach as a kid.
we have a couple near our house. They are only moving when the price of oil is up. Otherwise, they sit still. The cost of oil has to justify the electricity spent to run the pumps and get the oil out at a profit.
Joseph Haddakin Signal Hill right? My grandfather used to maintain them.
Ditto, and in Wilmington too.
Come to Texas.... they're in backyards.
Now that’s some cool technology
Have wondered about all that since I was a kid. Thanks.
In the second half of the 1960s we used to see a lot of them driving from Georgia to Illinois. This may have been before I was in kindergarten.
'The US and ultimately, the world' lol
Neat to see videos of a hit and miss Fairbanks that been running the same jackpump for 100 years in continued operation.
I am a petroleum engineer and have spent the last 20 years of my career in the oil and gas industry. Great video. Keep that oil flowing, it’s here to stay.
What are your thoughts about petroleum engineering as a career?
You would be better off to take mechanical engineering. It will get you the same type of job for an oil company if that’s what your looking for but at the same time you can use that knowledge in other industries as well.
Hi, I've watched the pumpjacks operate since I was a little girl (now, almost 55) along the California Hwy 101 corridor north of Paso Robles. I finally decided to find out how these things work today whilst driving by again. One thing this video didn't say is how the engine to make the spinner rotate, how does that work? It said gears, but does that itself run off of gas? Where does the power come from? I stopped one year to look at them up close, and their silence is weirdly frightening for such a large machine. I just still don't understand how they stay running. Can you help answer that question? Thanks! 😊
Most pumpjacks run off of electricity and are powered by electric motors. This is generally the cheapest way to run a pumpjack and as you mentioned are eerily quiet. The electric motor spins at a high RPM and rotates the gear box on the pumpjack which is belt driven. The gear box reduces RPM usually by a factor of 30:1 and increases torque the same proportion. The gearbox output shafts rotate at a low RPM but have very high torque. The shafts connect to the pumpjack through the pitman arms and this is where rotational motion is converted to up/down motion that you see the pumpjack doing. The whole process is incredibly efficient and well engineered. When the pumpjack head is at the bottom of the stroke, the counterweights are positioned at the top. As the counterweights fall, they help the motor lift the weight of the rodstring up (the rodstring is very heavy). Then the weights are at the bottom of the stroke, the pumpjack head is at the top of the stroke and the rods are ready to fall back down again. The rods descend back down at which point that energy is used to help move the counterweights back up. The weights are adjustable (the operator can adjust them back and forth) and this process is called balancing the pumpjack. A well balanced pumpjack will likely consume between $150 - $500/month of power depending on how much fluid the well is pumping. In isolated areas where there is no electricity , the pumpjacks run off of propane motors which are another piece of well engineered equipment. In some cases, the oil companies run the propane motors off of the natural gas that the well makes, also known as running your motor off of casing gas. Anyway probably more info than you wanted to know.
@Jackofalltrades837 Wow! Thank you, not too long at all; it helped make it make sense to me. I ride motorcycles, so I understand a little bit about rotation v torque ratios with the sprockets and gearing. The pumpjacks use such simple yet very effective technology; it's so facinating to me!
How did they make them run waayy back when they were invented? Was it circa pre-electricity? Sorry for so many questions. I'm ADHD and my brain makes a ton of questions to make sense of 1 simple answer!😬 I really appreciate you taking the time! 😃
I always thought they looked like dinosaurs as a kid
Erik well their pumping Dinosaurs out of the ground
I always thought they were called oil whales and I believed that cause of the hump type piece on the end
Spence H facts
As an Englishman, these don't exist in England, but I got to see plenty of them when I lived in the Middle East for a year, pretty cool you can just drive right up to them out in the desert. There also exists direct driven pumps that I guess just sucks the oil to a pipeline without a pumpjack.
As a fellow Englishman, you'll be amazed, but they do! (although not as widespread as in the US) Wytch Farm in Dorset being one place they operate, There are also other oil fields in the Midlands, Surrey, Sussex, Hampshire amongst other places.
@@therealchayd Oh wow that's really cool to know, thank you so much! I have a very keen eye for industrial/infrastructure things but somehow I was just never aware of these being in the UK.
@@Nitrxgen I know right? I was pretty blown away when I found out too! I may go and see if I can sneak a peek at them next time I'm down that way 😄
@@therealchayd I will also, but they look a lot more secure. In the middle east they're just in the desert with a dirt track, no fencing, no security, can just go right up to them as they operate no problem but Google maps shows that's 100% not the case at least in Wytch Farm. Let me know what you find?
in the us there are many of these in california especially los angeles but many are enclosed by structures to hide them.
Great video! Simple and short 👍🏻
Came here after watching the excellent movie "Hell or High Water" with Jeff Bridges and Chris Pine. Scene at the end on a Texas ranch with a number of these pump jacks. Thanks man.
No electricity neede?
The polished rod is attached to the horses head which is attached to the sucker rods.
Cool video. Thanks for making it.
Thanks! We’ve got a lot more like it 🙂 new ones every Monday.
here in central and Southern Texas you'll these anywhere you look at least I know what is actually going on in the process thank you so much 😁
I have 5 in my neighborhood! I live out in east Texas, Longview area.
This really helped, great video.
I've always wondered this.
I've heard some people refer to them as nodding donkeys
I was going to say the same thing, but you beat me to it. Maybe it's a regional thing?
Right on point. Great video.
They are utterly amazing and mesmerrizing
The pump and dump procedure.
You say the counterweight "helps balance out the forces" which is accurate but incomplete. I guess you don't realize HOW it balances the forces. The counterweight is set up so that it will take the same force to push the unloaded sucker rod INTO the bore as it does to pull the loaded rod OUT. This requires a much smaller motor than if a counterweight was not used. Instead of cycling between "full force" and "free ride", it's a relatively constant (and lower) force for the entire cycle.
Correct. Sorry if I wasn’t clear about that!🙂
I was about to comment about how the use of the counterweight is the real ingenuity of the device but whose explanation was left out - but you've hit the nail on the head. When the counterweight is falling with gravity assisting, the oil is lifting out of the pipe and a large force is required, mostly supplied by the counterweight/gravity, whereas when it is pushing back in, little force is needed, so the motor's power is used to lift the counterweight in preparation for the next oil lifting stroke. In this way the force is more balanced, and even a small motor can be used to heft a large head of oil up the pipe if one is willing to go slowly, since the small motor can be geared to rotate even a large counterweight, but more and more slowly as the motor gets smaller. Undoubtedly there are tradeoffs that determine the optimum motor, counterweight size, power consumption, and maximum oil seepage rates into the lift pipe that are made to minimize cost and maximize production.
Using a lot extra words to explain the same is that not 'overcomplete'?
@@Triggernlfrl No, none of what I added was said before. I'd say just the right amount of complete.
studworth gg
I like this explanation. I have one point though. Although the pump jack mae be called a derrick by some. It actually is the tower built above the well head used to install and remove the pumping rods or like had a pumping cable. Also the tubing can leak and have to be pulled out for repairs. These towers are seen in pictures for the earlier 1900s. Nowadays mobile well rigs do the job of the derrick. Sadly last year we had to remove our derrick and replace the cable and tubing and install a pumpjack. We loved the historical significance of the steam engine and belt wherl and left them standing.
Another version of the valve utilizes a series of large steel balls in series within a pipe sleeve at the bottom of the well casing. These balls moved up-and-down with the movement of the sucker-rod and with the arrangement of "ports" in the casing allowed the "lifting" of a pipe-pull of oil up and out of the well.

Thanks for the video
Brilliant explanation.
Thanks! 🙂
That's a pumping unit. A "pumping jack" is slang, for pumping money (jack) and generally not appreciated by all professionals in the oil and gas business. A derrick is the tall contraption that is the framework supporting a drilling apparatus in an oil or natural gas rig. The derrick derives its name from a type of gallows named after Thomas Derrick, an Elizabethan era English executioner. #texas #crude
Ann Eagle thank you for clarifying that. It irritated me. Lol
Not to mention they are showing mark units in some pictures conventional in others and a pump design I highly doubt anyone uses anymore.
It's not a riding valve it's a traveling valve. SMH this is a gross over simplification of what is actually happening.
Some information is just false. The size of the well bore has less to do with total fluid than pump size and formation pressure.
The third pumping unit design shown -- the one close to the ground, with rotating crank, counterweights, and horse head but without the long horizontal "walking beam" is a design that sits close to the ground in farm fields, so that movable irrigation systems can pass over the top of it without striking it.
@@joshualehman685 ....
with the same stroke, doubling the bore obviously gives more volume. But that also increases the weight to be lifted... a limiting factor when youre down a few thousand feet.
@@hotrodray9884 well bore won't change the weight pulled. Depth yes bore no. The size of the bore and fluid production doesn't change after a certain point.
The pressure left in the reservoir determines the rate the fluid will articulate to the well bore. The other reason well bore isn't near as significant is you still product through a pump that is 1.25-2" in tubing that is normally 2 7/8". Based upon the depth of the well you have a maximum volume that can be produced through artificial lift alone.
Wow only 1-1.5 gallons per stroke. Thought it’d be a lot more.
WorldEagleKW From 1.5 to 10 gallons per stroke. 3:00
Half of that volume can easily be mud or "water"
That's actually a huge amount, that's like 1000 tons a day
These must be small 200' wells with mostly gas
it all depends on how often it strokes per day.
thanks for sharing this

Very helpful thanks!
Glad it helped!
do pump jacks have a personal motor or do they use electricity from a power grid?
It depends. Usually they’re run off the grid, some are run by solar, some are gas burning.
Most of the ones I've worked on used engines similar to hit and miss engines, 95% off them ran on natural gas that came from the same well. The rest ran on propane. Or they were electric motors that ran from the grid. That's in ohio though. I'm not sure about other states.
Some of the older ones actually ran on natural gas. Most of the time the newer ones run on electric power.
They used to use natural gas as it is common to be near oil deposits, however they used it more out of the efficiency that if they didn't use it, they had to just burn it as they had no way to transport the stuff.
Now they mostly use electric, as the engines are more reliable (funny how they seem to be well aware of this) and natural gas can be transported and sold these days.
NOOOOOOOOOOOOOO. Pumpjacks are NOT oil derricks.
Correct, as noted around the video 🙂
Word
Not in the literal sense no.
But in colloquial speech it's pretty common to call them derricks.
Thanks, effective tutorial.
Did my 22 years in the "oil patch", and was a roustabout, floor hand, trk driver, pumper and heavy equipment operator...

I think we need more goddamn people to point out these technically aren't derricks. 🙄
I even did myself! Check out the pinned comment 😊
Funny shit man! Agree
wish they're perpetual
Sometimes the natural gas (methane) from the well powers the pumps.
We always called them "grasshoppers"....or sometimes "hopper-grasses" if we were in the mood.
I grew up in Oklahoma so I’m very familiar with these pumps. There is a street in Tulsa that has an oil well pump in the middle of the street.
I wonder why the oil from these pumping machines has that certain unmistakeable smell?
As in the there’s a different smell to oil from these pumps or why oil smells like it does?
your smelling the gas, oil usually doesn't smell. H2s smells like rotten eggs.
synchro505 lots of raw natural gases mixed into the fluids. i work on a drilling rig and when we tap into the "pay zone" it burns your airways from the smell
Different oils smell different. There many variations. To the average person they just stink.
Texas crude oil smells different than Pennsylvania, etc.
@@jweezee11 What? First h2s is oderless and deadly which is why we ware h2s moniters. Also another reason for evacuation slides, there not just for blowouts. If that h2s alarm sounds you better be running and if you fall im not stopping to pick you up or were both dead. This is serious business life and death if you don't know don't say anything your bull could kill someone. If you breath h2s gas you drop dead on the spot period end of story.
This is not an oil Derrick. It's called a pump jack.
Technically, yes. Colloquially, this is referred to as an oil derrick, more specifically an oil derrick pump, pumpjack, oil horse, etc.
+Concerning Reality - Technically, yes. Using a very loose definition of a derrick then it could be referred to as such. Colloquially, an Oil Derrick is the mast structure on a Drilling or Service rig that provides support for the Crown block, drill line and Travelling block that are used to support, raise and lower the drill string for drilling, connections and tripping. in my years in the oil patch, I have only heard the mechanism you are featuring referred to as a "Pumpjack" or "Walking Beam pump". When rig workers talk about a derrick they are always referring to the mast on their drilling rig. When a hole is TD'd and it is determined that it will produce, the rig (With its Derrick) is removed from the site and moved to its next location, a production rig is then set up over the hole to prepare the well for production, then it is removed to allow for installation of the pumpjack if it is required.
Yep, you’re correct 🙂 I tried to present it with as many names as possible, but totally understand the technicalities.
mike Rightmire literally the same thing...
+Tom - Nope
Thank you!

To pump out oil you should use _oil_ to operate it. Hmmmmm.
Some use the gas that is brought up to operate natural gas engines to operate the pump

They are never called oil derricks or derricks.
Colloquially they are quite often. See the description or our pinned comment
@@ConcerningReality I'm not entirely sure that colloquially is quite the word you want. It may be referred to as a derrick by uninformed people who don't know anything about the industry. Colloquially means an informal term which it is not.
Sort of like calling a baby horse a pony. Many people do it but it is still not the correct term.
Excellent video . There is one thing he left out . At night you can see these pumps burning off oil . Shooting big flames off intermittently.
A bit late but if anyone reads this... What they're doing is flaring natural gas. It's much safer to just burn it off than simply vent it into the atmosphere for a few reasons.
I wish my country had these!
Good video very informative
I worked in the oil field for over 50 years, I never heard a pumpjack called a derrick.
I grew up riding on these in Texas!
This is used for very small oil wells. In Nigeria where oil is in abundant, we use what is called a Christmas tree set up in an oil rig. It's fast and completely automated.
Well this is automated as well
Get it "well" ahahaha
