In this video, Motley Fool energy analyst Taylor Muckerman tells us about a big new diversification move by Targa Resources Partners (NYSE: NGLS). Targa has traditionally been focused on natural gas in the Texas and Gulf Coast areas, but is now making a big play for the Bakken, which moves the company into crude oil. Because this is an area with such rapid growth for the upstream oil companies, pipelines from the midstream are in constant demand, which means this will likely be a great source of revenue for Targa. Muckerman tells us what this means exactly for it, and how the company plans to pay for this expansion.
