Those who live on or use water wells know that when water is pumped out that there is a cone pf dep[ression around the WellPoint. Water is removed, the surface around the well declines. at some point, if you are removing water faster than it moves through the aquifer you may dry out the well, regardless of whether or not the aquifer is recharged. Stop pumping and the water returns .

While I doubt that petroleum is being created as fast as we are pulling it out I can see that, until you drain the whole pool, that individual wells will see "refilling".

Somebody who isn more chemically astute than I will need to explain how the earth's inorganic rock gets converted into organic petroleum in a manner other than conversion of fossil life forms.
