The following video is from Tuesday's Digging for Value, in which host Alison Southwick, and Motley Fool energy analysts Taylor Muckerman and Joel South, get to the heart of the biggest stories in energy investing today.

In today's segment, Joel South talks about an intriguing development from EQT Corp. (EQT 2.48%) and Green Field Services, where the companies drilled a multistage fracked natural gas well in the Marcellus shale using 100% field natural gas. Using natural gas from close wells instead of diesel to power rigs could be another game changer as oil and gas companies continue to increase drilling efficiencies and thereby significantly lower costs.
