In some mining sites, over pumping of water causes sink holes, will there be sink holes in a Oil field?

Oil and natural gas--or even water, for that matter--don't reside in vast underground lakes. The oil we pull up out of the ground is stored within the tiny pore spaces of rocks; it's the fact that it's under tremendous pressure that "squeezes" it out of the rocks and into liquid. In other words, think of oil and natural gas residing in rocks that act like sponges that we can draw liquid out of.
Don't really know if over pumping oil can cause subsidence, though. Wouldn't be surprised if it could.

IN Poole Dorset at Wych farm the biggest on shore oil discovery contained in the united kingdom, they are pumping sea water down them this has a duel roll it helps push the oil to the floor and fills the void. those wells were going considering 1960 and there has been no subsidence as of yet.

As oil is pumped, it is replaced by water to avoid this very problem you questioned. If the oil were pumped and not replaced by another substance, there would indeed be a void underground, but that void would likely cave in, making it more difficult to pump remaining oil.

yes. when all the liquid oil or water is pumped out of an area it will fill with air and become a cavern, and if the weight of the dirt and rocks on the roof of that cavern become to heavy to support it will create a sink hole

Yes..
There are voids and the ground sinks..( Subsidance )
Pumping water out of the ground causes more
problems than pumping oil out of the ground because
water is shallower and more of it is pumped than oil.

no, its usually replaced by sand or water, and its not like there are caverns, sometimes it comes out of the soil and rock, or in strata
oil is taken too deep, not near the surface, not a danger if its that deep, the soil above it supports it.

oh yes, so they use somekind of gum or something to replace it,
oh hey, it is deep deep below, so it sink in large area,,,,, ?
