[@Chris_at_Home]

I worked many jobs around oil. I did a year doing seismic and then 8 1/2 years doing well logging (wire line) as both a field hand and then as a technician. Then I went into communications and helped set up communications on remote drilling sites in the Arctic. After that I did 15 years communications on a pipeline. Where I worked they would produce gas in zones above the oil and use the gas to lift the oil similar to how bubbles lift water to the filter in an aquarium. The gas separated at a production facility and injected back into the ground on an injection well.

[@ugochukwukingsley2200]

Wow... This is interesting...

[@Melonskull]

When the oil is extracted.. I see the term "million barrells per day" they dont really have just a million barrells sitting around to be filled do they?

[@Chris_at_Home]

@@Melonskull No, it is just a unit of measure of flow probably into a pipeline to a production facility to filter the crap out of it to make a product to sell. Thing like different gases, water and silt might also come up with the oil.

[@Melonskull]

@@Chris_at_Home ok cool. I was thinking that but I wasn’t seeing any actual storage of all of it somewhere lol I guess it will just go in to large holding tanks?

[@Chris_at_Home]

@@ugochukwukingsley2200 Yes i thought I did some pretty cool jobs. I was sent to many schools in Texas to learn about the electronics in the well logging tools. We used different types of radioactive sources, acoustics and electrical resistance in what was called open hole logging done before the casing is set to measure formation types. Then there were tools to measure production, things like flow rate, temperature, amount of water and even a tool that listened and could find a small leak. I did many things in communications traveling around Alaska and even some over seas work. Worked for a contractor turning up satellite links for the FAA around the state and ANC center for a few years. My last six years before retiring were working in the earth station that provides most of Alaska’s rural communications.

[@sigungajoshua6149]

God's greatest gift !!!

[@dougberrett8094]

Just a bit of extra info. TD does not refer to total depth as often as it refers to TARGET DEPTH! While logging is often done on a wireline, the gold standard is a core taken from the formation at the depth of interest. Not side wall coring, but minimally invaded core from the center of the hole. Many oil field service companies run a fleet of tools that will “log” the hole while drilling is happening. These tools allow the well to be steered into the best location. In today’s drilling, the production zone is more often horizontal than vertical. Measurement while drilling tools and steering tools allow the bore to be kept in the pay zone for a much longer time than a simple vertical well could do.

[@brianwilson4861]

You left out the process that makes this all worthwhile. Hydraulic fracturing or fracking as its called. After perforating the well you take 6 to 10 giant high pressure water pumps and you pump about a dozen olympic sized swimming pools worth of fresh water and spherical ceramic beads down the well hole. The pressure from the pumps is so high that it cause the porus rock containing the hydrocarbons to crack and the spherical beads become wedged in the cracks holding them open. This allows the oil to flow into the well faster and in greater volumes which allows the extraction to be profitable and worth the effort to recover it. Without fracking the oil couldnt be recovered fast enough to make it worth the effort. We take wells that stop producing and simply frack them again and many times they produce more oil than when they were first drilled and fracked. Sometimes a lot more. In my experience, oil wells are rarely plugged and abandoned. Even producing just one barrel a day is worthwhile. We try and recover litterally every drop of oil. Water is produced with the oil and is separated using gravity and the difference in buoyancy. The separated water goes through a vessel called a gun barrel which removes the smallest traces of oil from the water.

How does the cement not get mixed in with the water as its flowing upwards along the outside of the pipe?

[@OllyJC]

It's a common misconception that aquifers and oil are always in pockets/pools underground. They're typically contained within porous rock, so cement won't flow in very easily. That's why the perforation guns are required, to shoot large openings into the rock as a place for quicker flow

[@r6smurf186]

@@OllyJC thank you

[@efrencast5257]

However the cement is designed, water well be pushed out from the cement. Water is only need to activate cement, cement naturally pushes water out. And if the cement is dense/dry, it won't mix with water. Its the same way if you place a bag of cement under water, it will still perform in the way it was made for.

[@silverdrillpickle7596]

During initial drilling, the bentonite slurry enters and seals off the water aquifer.

[@chrislnflorida5192]

It's called Displacement. Sometimes when they pumping the Cement down hole, it will blow a hole in a formation and thats lost Circulation, perse. Then u have to pump down Cotton Seed Hulls, and many others to plug that hole before finishing the Concrete. Hello to Halliburton 😂

[@rancosteel]

What kind of cement is used for the pour?

[@gmale605]

It depends on depth and formation. There are proprietary blends used, but class A is commonly used with the addition of accelerants or retarders according to the length of travel through the casing.

[@joefish1439]

About 45 percent of a typical barrel of crude oil is refined into gasoline. An additional 29 percent is refined to diesel fuel. The remaining oil is used to make plastics and other products (see image Products made from a barrel of crude oil, 2016).

Hey i have a question, when oil is taken out of the ground, is some other liquid put in place ? or do they just let the ground cave or something because its just empty now?

[@deo1011]

@@JovvnnyD it depends on the type of formation. In some cases yes they have to replace the displaced liquid. It's also beneficial to them because the typically inject produced water back down and the oil goes to the top. Water floods. In tight formation then oil is coming out of tiny pores in the rock and there isn't risk of it caving in. Protecting formations is big time in the oil companies interest as it means money. Hope that helps.

@@JovvnnyD something that is kind of.cool is.they have actually played with fire flooding. Pumping o2 down and igniting the formation to get the oil moving. Not sure if they do that anywhere anymore though.

If u talking about when they drill past the Aquifer and there NO Water Flow, it's called Down Hole Pressure. The mud u mix during the drilling process, some will coat the walls and if the mud is too heavy u can blow out the wall into the Aquifer or if your mud is too light u could possibly have what's called a Blow Out, u definetly DONT want that.

[@draconusspiritus1037]

Especially on shallower wells. When perforating the shaft to allow access to the oil. If there is a very high concentration of Natural Gas, it is possible for the perforation process to cause more of an explosion within the well than expected. With the potential result of one or more sections of pipe being destroyed and needing to be replaced. As well, the 'Shotgun' used to perforate the pipe can be literally shot out of the well. To multiple hundreds of feet above the ground. Needless to say this can be quite dangerous for nearby workers.

[@Netron24]

Ib order for an explosion to happen there has to be oxygen, which is lacking down there

[@draconusspiritus1037]

@@Netron24 I've seen that shotgun fly 100+ feet above the well when an unexpected gas pocket ignited during perforation. The well pipe is usually empty of anything but air when the shotgun is lowered into it. Oxygen is only lacking down there while there is no open path to the surface.

[@alijahgray2675]

There’s a lot of things missing this isn’t how wells are done and I don’t think have ever been done they left out the fracin,plugs,drill outs,coil tubbing,and esps (or pump jacks)

[@seanpadgett3053]

They didn’t miss them out, they are not normally required, not every well needs frac, coil tubing etc. the same way not all wells need a nodding donkey. I have worked on thousands of wells but never one with a surface pump, they are only for sub hydrostatic wells that need pumps to flow.

[@iketank1970]

There are several types of wells so not having a pumping unit in the video doesn’t necessarily discredit the video. If you’re interested look up ESPs and jet pumps. We run a couple Reda ESP Wells and A jet pump at a location. A lot will depend on depth and volume available for what kind of pump is set up
