Blast bone is more projectile than it is a pet. You can not compare it to any other pet anways. It's job is going to ememy from your position like any other projectile.
About your question, oil drop locations on keeps are unique. You can walk overthem but atack through them too. You can use shalks on top level at oil location and you will se beetles at ram location. BUT this is only graphical, it dont deal damage. If it does, it should be a bug.
