The fluid is pressurized, and below a certain pressure it becomes economically unfeasible to extract the oil. The cavity is still "full". Some advanced methods involve pumping water into the "cavity" to cause the oil pressure to rise. Again, this isnt leaving a true unpressurized cavity. Finally, the matter extracted, while large in human terms, is very small in terms of mass of the earth. All that matter was theoretically on the surface at one time, so if putting it from underground to aboveground changes the movement of the earth, then putting it underground in the first place also should have changed the movement.<br><b>References : </b><br> The earth isnt incredibly likely to collapse.
