A great question...
I went to marathon Oil Labs and learned all about it one day.
The help force the oil out they pump in water and detergent. The oil floats to the top and they pump it out.

Well, when Oil is pumped from underground,the nearby oil beds get sucked in to the cavity. If you have seen the fire to Oil wells in gulf, you must have seen a jet of Firing Oil from the well. This shows that Oil is not really Pumped out but in fact it is forcefully THROWN out from wells And this reduces the internal pressure so after many years, the amount and force of Oil reduces and slowly that well turns in to DRY well.

Seems to me that if you pump the contents from a cavity then it would remain empty. Maybe later in years fill with dirt due to cave in or maybe a water stream finds its way to the cavity.

Our atmosphere a pressure of zero psig and I do not think that air would flow into an oil or gas reservoir that is under significant pressure.

seawater is pumped back down the well to make up the oil taken out.

Not 100% certain, but I'd figure that they eventually fill with water as many of them are in the ocean. Those that aren't are certainly below sea level.

I've always wondered that myself. now that someone else wants to know too I'm gonna find out.
