In today's "Where The Money Is" mailbag, Motley Fool energy analysts Taylor Muckerman and Joel South answer an investor who asks: Do you have an opinion on Oceaneering International (NYSE:OII)?

Oceaneering International is a "picks and shovels" investment in deepwater drilling: rather than investing in any particular drill site, you're buying into a company that rents drilling equipment. This can make it a safer investment, since you're not worried about the returns of any particular play -- and with deepwater drilling expanding, it can be a good entrance to a profitable niche. But could there be a better investment in this space?
