1. Oil-Producing Countries
Hey everyone! Do you know which countries are the top oil producers? The following countries are some of the major producers!
1-1. United States:
The United States is the world’s largest oil producer, producing about 20.3 million barrels per day!
(Note: One barrel is approximately 158.9 liters. 20.3 million barrels of oil can fill about 1,291 Olympic-sized swimming pools.)
There are many oil fields in places like Texas and North Dakota, and advancements in shale oil extraction technology have increased production!
1-2. Saudi Arabia:
Saudi Arabia produces about 12.44 million barrels per day and is a key member of OPEC (Organization of the Petroleum Exporting Countries).
It has the world’s largest oil field, the Ghawar field, and oil exports support its economy!
1-3. Russia:
Russia produces about 10.13 million barrels per day.
It has many oil fields in Siberia and exports oil actively to Europe and Asia!
1-4. Canada:
Canada produces about 5.83 million barrels per day, mainly from oil sands (sandstone layers containing highly viscous crude oil).
The oil sands in Alberta are especially famous!
1-5. Iraq:
Iraq produces about 4.61 million barrels per day. Many oil fields are located in the Basra region, and oil exports are the backbone of its economy!
1-6. China:
China produces about 4.45 million barrels per day.
Daqing and Shengli are some of its major oil fields!
1-7. United Arab Emirates (UAE):
The UAE produces about 4.23 million barrels per day.
Many oil fields are located in Abu Dhabi, and oil exports support the economy!
1-8. Iran:
Iran produces about 3.67 million barrels per day.
There are many oil fields along the Persian Gulf coast, and oil exports play a vital role in the economy!
1-9. Brazil:
Brazil produces about 3.17 million barrels per day.
The pre-salt deep-sea oil fields are the major production areas!
1-10. Kuwait:
Kuwait produces about 3.01 million barrels per day.
The Burgan oil field is well-known, and oil exports are the backbone of its economy!
2. Oil Extraction
Oil extraction is the process of retrieving oil from underground reservoirs.
First, geological surveys and physical explorations are conducted to confirm the presence of an oil reservoir.
Afterward, exploratory wells are drilled to verify the presence of oil!
2-1. Geological Survey
In a geological survey, the structure of rocks on the surface and underground is studied.
Geologists create maps to identify potential oil reservoirs.
Seismic surveys, which use seismic waves, are also conducted to get detailed insights into underground structures!
2-2. Drilling of Exploratory Wells
Exploratory wells are drilled to confirm whether oil is present in the reservoir.
By drilling exploratory wells, we can verify the presence of oil and determine if it can be commercially extracted!
2-3. Oil Drilling
Oil drilling is conducted to reach the oil reservoirs deep underground.
The following technologies are used in drilling:
Bit (Drill):
Used to cut through the hard underground rock.
There are various types of bits, depending on the type of rock, like roller bits and diamond bits!
Mud Circulation:
Used to carry the dirt and rocks produced during drilling to the surface.
Mud also cools the bit and pipes and reinforces the walls of the well.
Mud is recycled in a tank on the surface for reuse!
Casing:
Steel pipes are used to reinforce the well and prevent it from collapsing.
Casing prevents the well from crumbling and protects it.
Cement is injected inside the casing for additional reinforcement!
3. Oil Extraction
Oil extraction is the process of retrieving oil from drilled wells.
In new wells, oil naturally gushes out due to underground pressure, but over time, this pressure weakens, so pumps are used to extract the oil!
Extracted oil is transported by tank trucks or pipelines to refineries after the removal of mud and gas.
3-1. Natural Flow Wells
In new oil wells, oil naturally gushes out due to underground pressure.
These are called natural flow wells.
Natural flow wells can produce a lot of oil in the early stages, but over time, underground pressure decreases, and the natural flow weakens.
3-2. Pump Wells
When the natural flow weakens, pumps are used to extract the oil.
In pump wells, pumps installed on the surface draw oil from underground.
There are various types of pumps, such as rod pumps and electric submersible pumps (ESP)!
4. Specific Examples
Let me introduce some specific examples!
Shale Oil in Texas:
In the U.S. state of Texas, shale oil extraction is thriving.
Shale oil is oil contained in deep layers of shale, and it’s extracted using a technique called hydraulic fracturing (fracking).
Fracking involves injecting high-pressure water, sand, and chemicals to break the rock and extract the oil.
This technological advancement has greatly increased U.S. oil production!
Ghawar Oil Field in Saudi Arabia:
Saudi Arabia’s Ghawar oil field is the world’s largest oil field.
It produces about 5 million barrels of oil per day and is the heart of Saudi Arabia’s oil production.
In Ghawar, water injection technology is used to maintain underground pressure.
This allows for stable production over a long period!
5. Conclusion
I’ve explained in detail about oil-producing countries, extraction, drilling, and production!
Oil is an essential energy source for our lives, and its extraction and drilling require advanced technology.
I also introduced specific examples like shale oil in Texas and the Ghawar oil field in Saudi Arabia.
