Well intervention

Okay, so imagine you have a toy that you really like playing with, but sometimes it gets stuck or breaks and you can't play with it anymore. That's kind of like what happens with oil wells in the ground. Sometimes they get stuck or something breaks and oil can't come out anymore.

Well intervention is like a big grown-up "fixing" for these wells. People who know a lot about oil wells use big machines and tools to go down into the well and fix whatever is wrong. They might clean out any gunk that is blocking the oil from coming out, or replace parts that are broken. Once they fix everything, the oil can start flowing again like normal.

Think of it like a superhero team who saves the day when something goes wrong with a toy. They're like the superhero team for oil wells!
