What they don't tell you he is the component right behind the bit is called a housing. The housing has a bend in it 2 degrees or so and houses what is called a saund which sends a signal to the surface. The signals picked up by the locator which shows you a clock if you will 12 o clock being up three o clock being left 9 o clock being right and six o clock of being down. The bit is connected to an inner rod which spins all the time. The housing is connected to the outer rod which is turned to the needed Direction. The cuttings or spoils are removed by pumping mud through the pipe and pushed out around the outside of the boring pipe which is called returns. That's about as simple of an explanation as you can get.
Thanks for answering thais question bugging me.
Yeah them leaving out the locater is pretty strange. It's literally how you know where your steering lmao
@@achillesninja its literally just showing how the drill bit works, thats it. simple. They arent showing the entire process.
@@beedt714 its literally not showing how the process is done.
@@achillesninja it’s not , just showing how the it looks like…… 😂
Thank YOU! I have looked at many HDD videos and have never found an explanation of how they are steered..... And I think that is what most lay people want to understand....
It’s always a big win when someone describes an operation so thoroughly and clearly that fewer questions remain. Usually I have more questions.
This the third video I've watched trying to find out how the drill bit is steered. Thank you for explaining.
why do you need to know so badly please lmk
Finally got it! Well shown and explained and easy to understand! So it is simply not just a matter of boring, but depending of the type of formation use high pressure flow of the fluid in softer formations and in harder formation make use of the bend and also use the high pressure fluid and drill together. Very nice, straightforward and informative. 👌👌👍😉
Look forward to see how the last part of the drill looks above ground.
Thanks a lot you guys
if you're someone that doesn't know much about DD this vodeo won't really help you
Most of the questions I see are about how the cut up chunks, called cuttings in the drilling world, are brought back to surface. The short answer is that the special drilling fluid that is pushed out the end of the bit in the video has a high enough viscosity to pick up all of the particles and carry them back to surface on the outside of the drill pipe.
Thanks for the clear insight.
Not just viscous but also dense. The cuttings float in drilling fluid.
The visual is excellent and gives clarity to the verbal description.
This is awesome, especially when you start at about 5k ft., or deeper, and drill a mile in either direction, before descending vertical again.
The Horizontal Directional Drill knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the Horizontal Directional Drill from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the Horizontal Directional Drill is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the Horizontal Directional Drill must also know where it was.
The Horizontal Directional Drill guidance computer scenario works as follows. Because a variation has modified some of the information the Horizontal Directional Drill has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
This movie is the best about horizontal directional drilling technology
Bill Burdick is one of the number one people in the USA for Directional Drilling he owns DDC directional drilling company he's a legend in the industry
We, HC Construction and ARB, made the only subterranean river crossing on the Amazon River. 24" TransPeru Pipeline. Near Saramiriza Peru, Rio Maranon. 1996
That's amazing, I didn't know such technology existed. Man.
It can also be snuck under a neighbor's property and Steal from a different well
@@siruitebit I only deal with sellers who ATLEAST provide rough prices instead of everything being "quote only" because of how overpriced their stuff is....
One of the directional drill operators here mentioned that this may be the future of sulfide ore mining - low impact, backfilled with neutralizing cement powder and waste rock, very little mess. We've got the gold here, but mining must advance with the times.
The drill system is based off of a clock, the driller and locater have screens in which they watch the clock, the percentage, projected depth and the direction they are drilling. 12 o clock is straight up, 6 o clock is down, 3 o clock left and 9 o clock right and so on.
I myself am a driller
I'd be willing to bet it's a bit more complicated than what this video shows. A simplified version, yes?
Pretty much the basic simple version.
You have to factor your mud mixture, ground type not just rock and sand size of jets on the drill bit and reamer as well as the types of reamer you want to use after the pilot is drilled.
You the man, Mac!
This is all fine and well, bit it doesn’t appear to explain the technique for steering/plotting the direction in which the boring head is guided. Therein would be the skill underpinning the craft of the trade. Thanks
You're drinking my milkshake again, aren't you?
For me, the explanation of how the steering works in hard material wasn't clear.
Yeah, it sounded like they just repeated the regular explanation.
I was curious how they steered these drills after I watched the Chile mine rescue.
Wrong drilling rig bub.
@@JS-oy6nn I imagine it is similar technology.
@@Kosmopoli yes and no. On vertical hole the use “steering arms” that help steer the head. There’s 4 on the steer collar that deflect.
We use the horizontal drilling for pipelines. It’s really quite incredible what they can do. Have lots of pictures over the years of jobs I’ve been on.
@@JS-oy6nn Sounds like interesting and hard work. Thanks for the info I will research vertical steering drills. I am sure I have used services that are related to the work you have done so keep it up!
Now show us how conduit, cables, pipes, etc. are pushed through the boring done by this machine.
Happening on my street right now to install fiber backbone. Wondered how it worked and this explained it!
Great video, reminded me of all the old military training films we had to watch!
So THAT'S how it's done. Awesome!
Boring, haha get it? Whatever. Pretty cool though, had to go to about 20 sites before someone actually explained how it works, most articles and animations said "they steer where they want to go" duh.
+Ramon Hamm Your digging yourself a hole there! :p Not boring when this video actually explained the steering function. That was the part that I was interested in!
I agree, this the one that finally explained it!
+Ramon Hamm if something should be written, write it right.
online articles and book that are boring are simply not written in a way that keeps the reader interested, unlike a video like this where you can actually get explanations right.
Narrator sounds like Wade Goodwyn
Such an interesting technology.
This gave me the basic principals! Thanks!
10/10 incredible video🥶🥶🥶🥶🥶🥶
I get this, but what about the pipe behind the bit? How do you steer a solid piece of pipe around corners?
+Jake LaRoe Some sections of the pipe are flexible
sometimes you dont, and you end up with "keyseating". Essentially digging into the low side of the hole, due to obvious gravitational effects.
All metals have some degree of flexibility. Picture a railroad switching yard. Do you see curves in any of the tracks? Even though the track is a very strong steel, it can still be bent over a distance. The drill pipe is similar in that respect.
From the bottom end of the vertical bore hole, where the directional drilling begins, to the full horizontal direction may be a quarter of a mile. Over that span, the drill pipe can easily flex enough to accomplish the turn.
@@ldgrmp Bro, if the pipe drilled downwards ,( some slope value) then, after what distance we make the bore hole in exact Horizontal direction? OR there is some slope value up to downward bore drilling??
@@RandomVideos2 but all of the pipe would have to be flexible for you to shove all of the pipe passed a sharp corner, so that doesnt work if only some sections are flexible.
nice, one thing iv wonders about for years solved
So the long pipes can just bend and follow these curves?
There's a video here on CZcams showing a precisely steered drill bit that broke through the surface and is blowing mud all over someone else's property.
Link?
So Wintercreeks got a great backyard.. Reasonable rates, great personnel, as well as a couple triples that easily handle a five leg horizontal from 6500' up or deeper.. Meisner, hunton, Bromide second... Arbuckle... For us poor boys what a pass time. Pursuing our adolescent pipe dreams.. Amen
" I'm drinking your milkshake" !!!!!
Awesome video
This helps, looking to get the oil under my neighbors property without paying them for it.
lololololololololol
This was how the Kwaitis stole oil from the Iraqis which caused Saddam Hussein to invade Kwait.
its like the movie Tremors :P
不错啊 很形象
Pulling had to be temporarily stopped due to rig breakdown. Exit side( pipe side) is bank of pond and now it is raining heavily at the site. Water level increased up to hole level. Since rig side level is lower than pipe side level, water is flowing through hole from pond to rig side.Can you suggest any technique to temporarily plug the hole to prevent water seepage from pipe side to rig side.
And you can almost guarantee they'll hit every possible utility along the way
it doesn't explain one fk'n bit how the bit is steered... just some bullsht
Yes it does. The end section is bent and they rotate the drill string and stop it when its pointing in the direction they want it to go, then remove material with one of the two methods described.
@@NevadanHunter What is the "drill string"? Us layman who find this process fascinating but know nothing about it don't understand the terminology. I assume that it's a term for the whole line of pipe from the rig to the drill bit?
Where does all the loose soil go ?
And this is how cartels bring the pounds of cocaine to the US 🤣🤣🤣
Yes it would be much faster.
But required some testing and simulations.
Ohhh, so that's how it works! So... how does it work?
and and the cartoonists forgot to add in how the drilled soil left the bored holes.
Simple Jojo, the groundhogs carried in away in their backpacks!
Drop more videos please it's very helphul
When you drill and case horizontally, how does the drill pipe and casing actually curve to achieve the 90 degree angle??
lots of stress
informative
the simpsons did it first

Please how can i get the operating manual for p800 ton rig. Trying to learn how to steer and operate the rig.
Still, it doesn't make clear how the actual drill bit assembly is being redirected - "go left, go right ..up. down". Is there, for example, a hydraulic pressure coming along the shaft from the operator to make the bit 'lean' in a required direction? How does this work exactly - none of the explanations online seem to go into this.
spottymaldoon
6 months old but I'll answer anyway.
The shaft is bent, so the damn thing always goes at an angle xD
They have controls to measure the current angle of the bend, so they know it'll dig up, or whatever.
To dig straight, I think they just rotate the bend constantly, making a small spiral that looks straight.
spottymaldoon If I'm not mistaken the drill bit/rig has a bend in it to control direction..
Example...if the bend is in a downward position the drill boars upward.
The video shows this clearly if your familiar with subterranean drilling.
Hope this heled.

this video is wrong. and it will confuse you. Theres two styles of directional drilling machines. One style that drills through dirt, and the other style that can drill through rock and harder ground conditions. This animation is showing a rock drill, but drilling like a dirt drill would.
a dirt drill has a paddle at the tip. it points in the desired direction to achieve and you just dead push to gain a change in direction. if you want to go straight you spin quickly and push slowly.
a rock drill is different. it looks like what the animation shows, but whats wrong with the animation is that the tip spins at all times. the outer rod has a slight bend in it and thats how you get direction. the inner rod spins the tricone bit at the end, ill say it again, AT ALL TIMES. You cant push a tricone bit unless you were in softer ground. If you were to use this bore head in softer ground it most likely would not gain enough change in direction to complete the bore successfully. At no time will you ever see a tricone not spinning while the bore head goes through the ground! But what the animation might have been misunderstanding is the outer rod doesnt spin all the time. you will spin the outer rod to determine the direction you want to go like up down left right. and then you spin the inner rod and push slowly. the bore head has a slight bend in it that allows the change in direction when the outer rod is stationary in the desired position.
You are incorrect, the video clearly provides two examples of the BHA, one is the jetting assembly and the other is modified to use a mud motor. There are not two styles of drilling machines. Listen to the video again and you will see that they were indicating two methods.
What happens to the drilling spoils during the backream-pipe pulling stage? Are the spoils expelled from around the pipe opposite the puller-drill rig or do the spoils go up the pilot hole?
The spoils go both ways back to the machine and towards the receiving pit, you pre ream first to get all the spoils out and then you re - ream to make sure the hole stays open so when you back ream while pulling the pipe it has a wide enough hole
What is cost ????
Pls tell
Character In the video It's great, I like it a lot $$
I drink your milkshake
Neat, now I know!
Hi, am Hidayat ullah khan, 6miles depth of time many types of molten metal but after that what happen, bit broken, or work off, or tired to return? How many layers you touch each layer any air gaps or volume is seen, i guess layers no gap, thanks for video
Use this for geothermal power plant
So can this drill through limestone? For example, could
this technology bring water lines (community water) to mountainous areas that rely on wells that are not producing anymore?
Can drill through granite, it’s about money
can drill thru your vehicle then back into the ground
More than three type of drilling bit... But I know total four bit... Please give me one more name of bit????
How does the drill pipe bend through the curve and then come out straight?
They can deflect. Just like railway track.
It’s flexible
Would be better with a PDC bit
Is Mike Rowe speaking?
Type of fluid only water. Or any solution another
What happens to the spoil ?
What rotates the bit Downhole
This is interesting

I've wanting to see how they do it ! Was this clear? NO, Nope, Not clear at all. I will keep Searching.
Wheres the debris go?

Mechanism
i have mastered the 7x11 vermeer series ii directional drill , anybody got anywork for me? i would love to learn 20x22 auto loading drill anybody need any help?
This video should not be regarded as definitive HDD explanation... I drill ERD HDD Wells, and it is absolutely nothing like this... In comparison, this is so simple (slant rig etc) it’s embarrassing to call it HDD!!!
can you steer us to a better video explanation? they drilled below a river near me and i am very interested in how they did it.
hi
Lovely
But anyone here who can help me with either a video or manufacturer of a one metre diameter type of drill that can work on drilling out iron ores
S - its done by steering rod then it talks with the software..what don't you understand are you from Morocco
Pray to Rayan in morocco
but how those hard pipe bend
Each pipe bends a tiny bit. Over a long distance, it adds up.
you cant bend them by hand. but they do bend in the ground. that is not an issue. keep in mind that the pipe is hallow and not solid.
@@underlinehdd Sir/Mam , I've some doubt,
1. If pipe bent upward slope direction then, How sewage flow against gravity?
2. During the drilling process, the waste soils are we made, so How the soils are taken out from the underground hole?
Pls explain Sir/Mam.
@oneviwatara Material is displaced from the subterranean drilling equipment, and the subsequent pipe, thus it has to go somewhere. That somewhere is above ground where the equipment came from. You swap one for the other.

Literally told me nothing about how to guide the drill
Not informative at all.
