OPEC controls gas prices by either increasing or decreasing the amount of oil available. If the amount available goes down, the prices go up. This is the law of supply and demand.

When you limit production, slow down permit approval process on leases like the Biden administration has done you contribute to limiting the amount of crude oil available. When there is less crude the price goes up.
It appears you struggle understanding supply and demand so I have tried to simplify the process so you can understand that.
