Oil and humanity have been collectively for give up some time now. The enormous oil spill that occurred in the Gulf of Mexico and lasted for greater than 3 months testifies to that assertion. A few of us might help however surprise how we acquired into this mess. The spillage was finally stopped with BP inserting a tighter fitting cap on the properly adopted by a course of referred to as “top kill to permanently stop the move of oil. We know BP was sloppy with this oil nicely and cut some corners to tap that large reservoir of oil three miles below the water surface. However what we need to do is return in time and comply with the historic path to when man and oil first came collectively and move forward to the place we are actually. Before I get started, allow us to take a look at how all that oil received down there under the bottom in the primary place.
How Did The Oil Get There
It started 50 million years in the past when dinosaurs roamed the Earth and all the continents had been collectively as one giant landmass known as “Pangea”. During that point, the ancient ocean was filled with zooplankton, microscopic organisms. As these organisms died, they fell to the ocean floor and formed a thick layer covering the ocean floor. This process went on for hundreds of thousands of years and continues to be taking place. Later by way of the technique of plate tectonic (movement of the earth crust) these layers of useless organisms have been pushed deeper in the Earth’s crust. It’s right here the place buried layers of useless organism were subjected to high stress and temperature for millions of years and converted right into a waxy substance called “kerogen”. Kerogen is wealthy in carbon and hydrogen. This waxy substance migrated by means of porous rock and collected in pockets as deposits of oil and gas. Land lots continued to shift, sea levels changed and these ancient deposits ended up beneath many places all through the world akin to Texas, Alaska, the Middle East and under the seas.
When was oil first found
Man first came across oil throughout historic times by actually walking over it. Oil was usually discovered bubbling up through the ground in some places. Should you remember the Television collection “The Beverly Hillbillies” that’s how Jed Clampett bought rich. He noticed oil bubbling up out of the ground while hunting. The Chinese language has used oil since the 4th century B.C. Oil was used primarily as a lubricant, lighting, and as a caulking for ships to make them waterproof. Believe it or not, oil was also obtained by skimming it off the water in some ponds because it was typically discovered bubbling up from under the water floor. This apply continued until the 1850s and acquiring oil from whales was beginning to grow to be scarce since the whales were practically hunted to extinction. Oil producers started to search for different sources of oil. Oil drilling started in 1848 in what’s now Azerbaijan. At the moment Imperial Russia was the most important producer of oil on the planet with an output about 7,000 tons. By the beginning of the 20th century Russia produced greater than half of the oil on this planet. In the United States Colonel Edwin Drake built the primary oil effectively in Titusville, Pennsylvania in 1859 and struck oil after drilling a mere 70 ft down thus beginning the “modern oil era”. By 1925 the U.S. over took Russia in oil output and became the world’s largest oil producer. Oil wells turned the principle supply of kerosene for lanterns. Until that time, combining turpentine with whale oils was the primary approach to provide illumination. By the 1920s oils fields have been found in Ukraine, Canada, Venezuela, Sweden, Poland and the United States. The Gulf of Mexico did that see it first oil well platform in the water till 1947 off the coast of Louisiana. This well was only eleven miles from the shores. After World Battle II ended, United States lost its lead in oil production to the Middle East international locations.

At first, the demand for crude oil was not as high as it’s at present. In actual fact, a lot of the crude oil obtained from drilling back then was discarded. Yep, discarded. In the course of the late 1800s the kerosene element of the oil was the only usable a part of the oil at the moment. Fifty years later the demand for crude oil went up dramatically with the mass production of the interior combustion engines nonetheless used in most vehicles and trucks at this time. Oil wells started springing up just about all over the place to fulfill this excessive demand for oil. Unfortunately, drilling for oil could be very dangerous and expensive. For each one hundred oil wells drilled solely forty four produced oil and clearly it becomes even dearer and harmful when drilling for oil offshore. It value about 80 dollars a barrel to drill for oil offshore examine to drilling for oil within the Middle East at 5 dollars a barrel.
Earlier than any drilling can be done, an oil reservoir have to be situated first by utilizing several strategies to positioned it. Gravity meters are used to locate oil reservoirs by measuring small changes in gravity caused by oil reservoirs. Magnetometers are use to detect small changes in the Earth’s magnetic subject brought on by flowing oil, and electronic sniffers are used to detect the smell of hydrocarbons. Lastly, the commonest method employed is the usage of shock waves. When shock waves are emitted into the bottom or water they journey by totally different materials at different speeds. In some cases these waves are mirrored back to delicate detectors on the floor the place the readings are interpreted by seismologists for indicators of oil and fuel traps.
Once a site is chosen, legal matters should be settled earlier than drilling can begin. The location should be surveyed and boundaries have to be established. The positioning must be checked for environmental affect and a supply of water should be near by if drilling going to be achieved on land. If no water is near by then a nicely should be dug. After the land preparation is completed, a number of holes are dug in preparation for the rig (derrick) with a rectangular pit referred to as a “cellar” for the drilling gap. Lastly, when the holes are completed the rig is introduced in and set up.
As a way to carry out oil drilling, three programs must be in place. They are the facility system, mechanical system, and circulation system. Diesel engines on the positioning present the principle supply of power and energy to run the electrical generators to produce electricity for the drilling platform. The electrical generators present electricity to the electric motors to energy the mechanical system. The mechanical system is consisted of a power hoisting system and a turntable. The hoisting system is used to lift and move heavy equipments and materials (pipes, pumps, and so forth) around the platform. The turntable is the main a part of the rotating gear that does all the work on the platform; it turns the pipe with a drill bit on the end during drilling. In addition to the turntable, the rotating equipment is consisted of several components such as the swivel, kelly, drill string, and drill bits. Every performs a important function in the process to manage the pressure in the nicely. For example, the swivel operate is to type a tight seal round hole and the drill string serves as pipe connector thus increasing the load on the drill bit. The ultimate system is the circulation system. This system performs the job of pumping drilling mud (mixture of water, clay, weighing materials and chemicals) into the outlet to remove rock reducing from the drill bit. But earlier than this may be carried out the opening is first lined with a concrete casing to stop collapses. Finally, simply below the rig crucial piece of the drilling process, a blowout preventer, is put in place. That is the piece that failed in the Deepwater Horizon accident within the Gulf of Mexico. It function (with the usage of excessive-stress valves) is to seal the excessive- pressure drill traces and relieve pressure. This release of pressure now and again prevents an uncontrolled gush of gasoline or oil to the surface.
Oil Well Drilling in 5 Steps
Once the rig is set-up and a starter gap is accomplished 5 basis steps are performed to drill for oil.
Place the drill bit, collar and drill pipe in the hole.
Attach the kelly and turntable and begin drilling.
As drilling progesses, circulate mud by way of the pipe and out of the bit to take away rock cuttings out of hole.
Add new sections of drill pipes as the opening gets deeper.
Take away the drill pipe, collar and bit when pre-set depth is reached.
Then the rig crew pumps concrete into the outlet to type a casing and let it hardened. Lastly when the casing hardened an explosion is ready off on the pre-set depth to interrupt the casing to permit oil to circulate up the pipe. Lastly, the crew connects a device referred to as a “Christmas tree” to the top of tubing and cement to the top of the casing. The Christmas tree thems to control the stream of oil.
Despite all of the dangers and bills of drilling for oil, the demand for it is going to remain high for fairly some time. The desk beneath reveals some of the explanations we want oil.

The process begins by drilling a petroleum refining process animation 500 gap deep into the earth. To do this, a protracted bit connected to a “drilling string” is used. The bit varies in diameter from five to 50 inches. After every section is drilled, a steel pipe slightly smaller than the opening diameter is dropped in and infrequently cement is used to fill the gap.

If you happen to get up at some point and are lucky to seek out oil coming up from a gap in your back yard. Who do you name, and how do you cap it
ValveWrenches, I used to be shut.
Melpor, I don’t work on a platform, but I own and operate a supply house in Georgetown, TX. I additionally run a manufacturing firm that builds Bleeder Cleaner tools for refineries and chemical firms. The whole lot I do is some what related to the oil business.
ValveWrenches, thanks for the comment. Hey, your title seems like you’re employed with high pressure gear. Do you work on an oil platform
ValveWrenches 6 years ago from Georgetown
I appreciated the simple explanation to an advanced topic.

This is a great and informative hub, Melpor. I usually have questioned at the small print surrounding oil drilling, so thanks very much for sharing this information. I chuckled when you mentioned the Beverly Hillbillies, as a result of that was within the petroleum refining process animation 500 again of my thoughts as I was studying that earlier than I even acquired there lol. Very useful, and liked the diagrams and pictures too.
