On April 12, Chevron revealed that it had entered into an agreement to buy Anadarko. The deal would shake up the U.S. upstream sector, creating a company that rivals ExxonMobil domestically, according to GlobalData.

Following the agreement, Occidental Petroleum Corporation made a proposal to acquire Anadarko on April 24. Occidental’s proposed Anadarko deal would put the company alongside ConocoPhillips in a peer group of two as a “super-independent”, according to Zoe Sutherland, a corporate analyst at Wood Mackenzie.

On April 23, Murphy Oil Corporation revealed that its subsidiary, Murphy Exploration & Production Co. – USA, had entered into a definitive agreement to acquire deepwater GOM assets from LLOG Exploration Offshore LLC and LLOG Bluewater Holdings LLC.
