i just noticed someone from or contracted by the power company drill holes and add what looks like oil then plug the hole in large powerline poles that run on my property. it was down at ground level. does this work for prolonging the life of the pole?

I'm guessing they put in Cuprinol which is used to protect the posts below ground level. I think Cuprinol has pretty much replaced the old tar stuff.
