In this segment of Investor Beat, Chris Hill and Motley Fool analyst Mike Olsen tap into why Core Laboratories is a stock to watch, especially since the core and fluid analysis company offers 50% returns on capital.

He's keeping an eye on this company to see what happens when the exploration of the shales moves toward the development phase.
