Leverett J-function

Okay kiddo, so imagine you are playing on a seesaw with someone who weighs the same as you. When you both sit on opposite sides of the seesaw, it stays balanced and doesn't move much.

Now imagine that someone much heavier comes along and sits on the other side of the seesaw. Suddenly, the seesaw tips massively towards that side and you are lifted high up in the air.

This is kind of like what happens when we talk about the Leverett J-function. It's a way to measure how much oil or gas can come out of a rock formation, like a seesaw tipping one way or the other.

The Leverett J-function depends on how much water is in the rock formation, and how easily the oil or gas can move through the rock. If there's too much water, the oil and gas can't flow out easily. But if there's just the right amount of water, the oil and gas can flow out more easily, just like how the seesaw tips easily when there's just the right amount of weight on it.

Scientists use the Leverett J-function to help figure out how much oil and gas can be extracted from a rock formation. This is important because oil and gas are important sources of energy that we use for things like heating our homes and fueling our cars. The Leverett J-function helps us understand how we can get more of these resources out of the ground.
