If you placed a perforating gun 2000 ft underneath the ground and ignite the charge. Which direction would it blast? If you were do the same, but the depth was 200 ft, would you expect the same direction? Why?

Unless you are using TCP with an orienting sub, or some gyro method with wireline guns, you cannot orient wireline guns. I have not heard of any orietation for wireline guns. Guns run on wireline, assuming equally balanced, will rotate as per well geometry with turn and when blindly perfingbat 2000 ft and 200 ft the holes will be oriented differently.

At 2000' assuming maximum stress is in vertical direction, the fracture will move in vertical direction. And at 200' the fracture will move in horizontal direction.

It will blast in the direction of the minimum horizontal stress

don't you aim perf guns? Perhaps he is looking for the direction of the least horizontal stress in the earth ?
