Parsley Energy repeats its growth formula with an equity-funded $2.8 billion acquisition of Double Eagle's Midland Basin assets. Parsley has been on a Permian tear.

Matador and SM Energy both raise the bar for well results on acreage they acquired through M&A, highlighting some unique areas for even more future Permian investment.
