The Bakken you started your career in doesn't exist anymore.
In just 18 months, over $90 billion in mergers and acquisitions completely rewrote who runs North Dakota's oil patch. Companies that were household names on location (Hess, Marathon, Enerplus, Whiting, Oasis) are gone. Swallowed up.
Eight operators now control roughly 80% of Bakken production. If you're wondering why the vibe changed, why the logos on the trucks are different, or why your company got a new name, this is why.
