Deepwater drilling is when people go underwater and drill for oil or natural gas. The water is very deep, like when you jump in a pool and try to touch the bottom, but the drill goes much deeper than that.
To do deepwater drilling, people use a big ship called a drilling rig. The drilling rig has a long stick with a drill on the end. The stick is called a "rig" or a "derrick."
The rig is lowered into the water until it reaches the ocean floor, which can be very far down, like taller than a skyscraper. Once the rig reaches the ocean floor, it starts drilling into the ground to find oil or gas.
The drilling rig has special equipment that allows the workers to see what's happening deep under the ocean. They use cameras and sensors to make sure they're drilling in the right place.
When they find oil or gas, they use a pipe to suck it up to the surface, like a big straw. Then they put the oil or gas in a tanker ship and bring it to shore, where people can use it to make things like gasoline or heat their homes.
Deepwater drilling is very challenging because the people have to work in the middle of the ocean, where there are lots of waves and storms. They also have to be very careful not to damage the environment when they drill. But they do it because finding oil and gas is important for our everyday lives.
