When oil is extracted out of the ground, what is put back in to stabilize the cavity when it is drained?

Not necessarily anything.
However, seawater or brine, is often pumped into the well to effectuate the process and "take its place"
Sometimes air is pumped in.
Japanese are experimenting with pumping carbon dioxide into the earth, though not oil wells yet. Some think that injection wells will be the cheapest and easiest way to bank carbon dioxide, and the pressure will help free up more oil.
Seawater is more effective, when readily available, because the process heats it up quite a bit, and makes the oil flow more easily.

Crude oil and organic gas are made from very tiny pore areas interior not person-friendly rocks lots of that are such as concrete. those pores are such as the pores on your pores and skin which permits perspiration to happen without your body collapsing once you perspire. Your body merely creates further fluids as mandatory and strikes those fluids from cellular to cellular. there is not any underground "lake" of crude oil that could then reason a crumple once the crude oil grow to be bumped off. also, salt water strikes into crude oil reservoirs to interchange the oil it really is bumped off in numerous reservoirs in the different case we pump salt water into the reservoir to improve stress and help to push the crude oil out. In some very mushy, shallow reservoirs the floor can actually subside some inches by skill of the years because the stress interior reservoirs is depleted. inspite of the undeniable fact that, to mitigate that back we pump water into the reservoir to save stress extreme and hence ward off subsidence from occurring.

It's also worth pointing out that there isn't a cavity. Oil tends to be found in porous rock. Think of a sponge soaked in water.

we will be forced to burn camels sh*t to produce energy as all Arabs countries producing oil, will be forced to ride camels again.
