A B&R rig is a big machine used to drill holes in the ground so people can search for things like oil or gas. Think of it like a big straw that goes deep down into the Earth.
The machine has a really powerful engine that makes it move and spin a long pipe called the drill stem. The drill stem has a special drill bit on the end that can cut through rocks and dirt.
As the drill stem spins and cuts through the ground, a special liquid called drilling mud flows down the pipe to help cool the drill bit and carry the bits of rock and dirt back up to the surface.
All of this work is done by special people called rig workers who make sure the B&R rig is working properly and keeping everyone safe. They work long hours and have to wear special safety gear to protect themselves.
When the B&R rig is done drilling, the workers take a sample of the stuff they found and send it to a lab to be tested. Sometimes they find things like oil or gas, which can be really valuable. Other times, they don't find anything, but that's just part of the process. So, in short, a B&R rig is like a giant straw used to find valuable things deep in the ground, and it's operated by skilled workers who take safety very seriously.
