Vanguard Natural Resources (NYSE: VNR) is a company that's been making some very strategic acquisitions. This isn't a company that discovers its own sites; it purposefully selects mature, long-lived oil or natural gas fields to acquire, which makes its capital expenditures far less risky than those of some of its competitors. It has made 17 of these acquisitions in the five years it's been operating, totaling $2.5 billion, and the company now has positions in most of the major U.S. plays. This has led to incredible stable growth for the company, and excellent dividend yields for investors.
