I started roughnecking in the oil fields in August of 1958 and worked for the next 54 years. Never missed but just a couple of paydays during that time. I started at the bottom, started working lead tongs, then backup tongs, motor man, derrick man and driller. I finished working 46 years as a directional driller. Had a good life and would do it again it I had to. Made more money than I could imagine. I retired at the age of 72 and in good health and with all of my fingers.

Howard Hughes's father invented that drill bit and it's still in use today. This film really shows how it's done.

[@16mmEducationalFilms]

That's one good invention!

[@EDesigns_FL]

Howard Hughes, Sr. did not invent the rotary drill bit, but he was the first to file a patent on it. As an attorney, he knew how to capitalize on other people's failure to secure IP rights. His real genius was in leasing the bits rather than selling them. It has taken others a century to appreciate how lucrative this business model is.

[@billwilson3609]

Legend has it that Hughes' father bought the rotary drill design from a drunk engineer that needed money at a Shreveport, LA tavern. Howard Sr. then had a few made in Shreveport to test in the Smackover Play before filing a patent on his final design. Then he leased the bits so he could get them back to be resharpened and leased again. He probably required a hefty deposit for each one to ensure he got them back.

We had a nipple up shop, them & the on call welder would be out at the rig as soon as the casing was run and cemented in, welder would weld the flange on, nipple up crew would attach the BOP, and the driller would have the fellas start tripping back into the hole. BOP was a piece of case pipe until you needed to control a gas kick. If the pipe started coming back out of the hole, there are rams that shut, severing the drill string and closing the hole. Then everybody runs like hell anywhere but there.

What's crazy is even then there was the concern of low oil😁. I can kinda understand why hydrogen and EV vehicles are trying to be a thing, sorta. Technology have significantly change since this video, cars are more efficient than ever, I'm positive we'll have plenty of oil during my lifetime

[@AirstripBum]

There will always be plenty of oil. It's the second most plentiful substance after water on Earth and it replenishes itself. They want you to think it's scarce to keep the price up.

[@billwilson3609]

The US DoD hired Exxon in the 1960's to explore the use of hydrogen as a fuel for vehicles. Exxon got Texas A&M to help out where they determined the cost of the special alloys needed for the engine, line fittings and storage tanks made hydrogen too expensive to consider using. In the 1980's Ford looked into developing engines that ran on hydrogen and shelved the plans after determining the cost would add 30% to the cost of a standard car. Then the Big Three automakers looked into shared platforms for lighter weight cars and trucks using the same engines, drivetrains and suspensions with different style body panels and interiors that snapped in place like Lego blocks then bolted down. The idea was to have the components shipped to regional warehouses around the World where unskilled workers could assemble vehicles when orders came in. Two engines were to be offered with one being Diesel and another with a plastic block that ran on methanol. The methanol engine was for urban use and in regions were methanol was easy to produce like Brazil. They cancelled the project when they sensed that the public around the World had no interest in anything like that.

[@partsshooter]

@@billwilson3609 plastic engine blocks! You know I thought of this randomly. How greedy could manufactures be to produce something like that🤔? in today's time that is.

[@billwilson3609]

@@partsshooter Wasn't due to greed but to reduce the weight of the vehicle and increase the power and mpg's by using ethanol. The block was to be made from high strength and heat resistant plastic. The only metal parts were the crank, bearings, rods, pistons, cylinder liners, cam, head, valve components, water pump and bolts. The combustion chambers and piston crowns were to be coated with a ceramic with the motor oil being a lifetime silicone lubricant. It was designed to run at very high rpm's on a very lean mixture with the power going to a multispeed automatic transmission that would allow it to get around 70 mpg in town and over 100 mpg on the highway. They figured that cities around the World with smog problems would be interested in seeing vehicles using those being sold there but weren't, so they cancelled the project. I'm sure they still have the plans on hand since producing ethanol is a lot easier and cheaper than rechargeable batteries. Back then they also had designs for plants that took in municipal trash, removed the metals, glass and plastics then ground-up what remained into a mash that had yeast added to ferment the sugars into alcohol. Then the mash was distilled to remove the alcohol then cooked longer to extract the water for reuse. Then the dried out mash was transported to farm fields to be plowed under to add nutrients and organic matter to the soil. They figured those could be built by existing sanitary landfills since those could be mined once conservation measures have people producing less trash.

from a technology perspective, a lot has changed, but as always, it depends how much you want to spend.

[@cerealport2726]

drilling fluids have changed a lot, though the simpler water-based ones still have their place. essentially it is water, plus a weighting agent (often barite), a viscosifier (like bentonite), potassium chloride to reduce reactions with clays in the rock, plus or minus some other additives to control pH and other properties. oil-based muds are more complex and expensive, but have advantages over water based fluids. Halliburton (Baroid) and M-I SWACO (now part of Schlumberger) are 2 companies providing specialized drilling fluids today.

I question the popular notion that petroleum is a fossil fuel. The deposits of petroleum exist far deeper than any fossil bed. How did the petroleum get so much deeper than the deepest fossil bed? It would be somewhat understandable if petroleum was just a tiny bit deeper than the deepest fossil beds. But it is much, much, deeper. Also, the easy petroleum to get was extremely shallow. Some surveys of depleted wells found the wells filled with petroleum again. There is no explanation for that. Besides all this, why is petrol still a fuel for automobiles at all? Why has the planet not moved to diesel? That is the forever fuel.
