The oil is there for one purpose ,thats to lubricate the compressor ,but it also traveles with the refrigerant through the system and when you have a leak it will be forced out the place where you have the leak ,thus after awhile you will lose some oil ,generaly the leak will be around the seal in the compressor.
Add oil to your engine and see if it will restart. then take it to the nearest service shop to have the oil leak repaired.
