Is it possible emptying all those oil reserves could cause land to sink or even earth quakes?

Sinking, conceivably. Some degree of subsidence could be detected at surface level, even though oil is usually quite deep. There are cases where subsidence was caused by excessive pumping of the water table.





Earthquakes: perhaps a minor tremor from a cave-in deep in the earth, but a major quake, no.Is it possible emptying all those oil reserves could cause land to sink or even earth quakes?

no because the land above the reserves push down at the rate of the oil being pulled up... so no
Sure even though they are supposed to inject saltwater to fill um up after but oil is lighter than water.
