Like laparoscopic surgery for the earth, horizontal directional drilling (or HDD) doesnāt require digging open a large area like a shaft or a bore pit to get started. Instead, the drill can plunge directly into the earthās surface. From there, horizontal directional drilling is pretty straightforward, but itās not necessarily straight. In fact, HDD necessarily uses a curved alignment to enter the earth, travel below a roadway or river, and exit at the surface on the other side.

I work in the fiber optic network industry, and previously worked in the gas utility industry. We used to joke that you should always carry a length of fiber optic cable with you in case you get stuck on a deserted island. Just bury the cable and when the guy with the backhoe comes out to cut it you can just ride back with him.

used to work on a directional drilling crew. very cool. we were a small company and one day we hit a big set of fiberoptic lines. poor company went bankrupt after paying for repairs on that fiber.

I used to work for a UK drilling company as a tracker. We drilled under railway lines with mm tolerances on the tracks. Under woods that had preservation orders and under lots of domestic properties. We drilled under a river aiming for a range rod that the client had stuck in the ground. I will never forget the look on his face when we emerged from the ground and knocked the rod over.
We used to say " any fool can still down. Coming back up and arriving where you want to be takes skill.

I worked installing fiber optic cable when I was in high school, horizontal drilling 4ā underground in residential areas. I was the guy who used a hydrovac to expose existing utilities before drilling so you didnāt hit them with the bit.
I then got a degree in petroleum engineering and work in the oil and gas industry drilling horizontal wells. The concept is identical and many technologies are shared , only difference is you start going horizontal at 10,000ā instead of 4ā!!

That string in the gel demo was awesome and gave such a simple and precise explanation of a problem that I always wondered about. Beautiful!

Here in Germany that drilling method did become more known to the public when the company "FlowTex" was sued for the (back then) most expensive large-scale fraud in Germany. The damage was roughly 4.2 billion USD.
The company had 270 machines but those were sold multiple times (3142 machines had been sold).
When they had investors visiting they drove to one drilling site, then had lunch and then drove to a different drilling site. During the lunch brake they moved the drills from site 1 to site 2 creating the illusion of a bigger pool of machines. (see my correction)
Correction
The scam worked more like that they changed the serial number plates on existing machines with new created serial number plates.

Thanks Grady! This answered so many questions that I didnāt even know I had. We had one of these drill right through the water supply to our house. They were like, āthere isnāt a pipe hereā and I was like, āwell, thereās no water going into our house anymore soā¦ā
They had it all patched up in a couple days.

As a utility locator, The talk about the potential impacting of other underground utilities was greatly appreciated. Always call before you dig!

I assisted an HDD on Mariner East 2, ME2. We had an inadvertent return so bad we built a pit around it and simply used it as a recirculation pit. There was a lot of effort to mitigate damage professional geologists at each drill and field techs/engineers walking the surface to look for IR's. Amazing tech

Having recently experienced fiberoptic cable installation in my neighborhood, I can confidently say the lack of trenching was both noted and appreciated

I could never have imagined how you can steer a long, flexible drill bit. After you explained it, it seems so obvious.

The drill bit 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 drill bit 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.

My hone region of ohio is known as "DD paradise" because there are 50 or so directional drilling companies based in a 20 Sq mile area. Also 4 years ago, TC Energy did a reconstruction project on the east buckeye express 36in diameter natural gas pipeline which travels underneath 3 major waterways in my region. My favorite way to kill time was to go out and watch the semi sized drilling rigs boring and pulling up to 3 miles of pre-bent thick wall pipeline on the ROW.

that's super interesting its also similar to how the apollo capsules were steered on reentry. The mass was off center so by rotating the capsule it could change pitch or yaw

I work at an Engineering firm and have designed multiple directional drills across intercoastal waterways. I now use this video to introduce new engineers to the basics of directional drill. Thanks for putting this together. Also, I see you used to work for Freese, we are partnered with them on a project. I'm a Kimley-Horn guy.

I studied geology and worked with directionally drillers at a utility contractor. Their biggest challenge the drilling foreman told me was hitting hard rock at glancing angles. The problem project that eventually had to be trenched was at the foot of the Wasatch mountains and they hit a high quartz content sedimentary layer less than 30 degrees from parallel to it and it just skipped along the outside edge of that fold and came out where they didn't want it to. They had drilled right through it at more square angles where the bit would be forced to go ahead and chew through that harder to cut rock.

4:50 bentonite needs hours of mixing to shear so it creates the shear-thinning fluid it needs to be able able to suspend cutting while pump is off. Posting this comment while my drilling bit is drilling at 14,000 ft below ground. I always liked the way u demonstrate concept and really liked how u showed how mud supports well walls.. one more thing is also when water infiltrate in permeable sand leaving solids on wells wall which supports it which we call filter cake. Ty for ur quality content and good presentation. Glad i found something to relate to in ur channel.

I live a few miles from an area that was affected by the Mariner issue and it was downplayed and covered up more than you could imagine. They struck old mine shafts here which leaked blood red water into the river for weeks. There was coal ash making its way into the river. Cutting fluid which they were caught using something other than what they were supposed to be. It's been a while but now I'm going to look into it more again.

I once wrote a guidance program for a pneumatic directional drill head. It allowed for horizontal and vertical profiles, and I had to invent a method for aligning two vectors in space using at most 2 curves with a minimum radius of curvature (it involves normal vectors to planes and an iterative approach). The drill head was one of a kind, with no mud required and an average speed of 1 foot a minute. The contract fell apart though, due to various factors. It's still one of my proudest achievements.
