The following video is from Thursday's Digging for Value, in which host Alison Southwick and Motley Fool energy analysts Joel South and Taylor Muckerman dive deep into top stories for today's energy-sector investors.

In this segment, Joel looks at BP's (NYSE:BP) proposed Mad Dog oil project expansion, that is now proving just too costly to carry out. Joel discusses the cost inflation and price uncertainty that led to pulling the plug on this deepwater Gulf of Mexico project, and why this could be a positive sign for the company financially.
