ConocoPhillips' Marathon Oil Takeover: Is it Unlocking Superior Value?

By Nilanjan Banerjee | August 27, 2025, 10:13 AM

ConocoPhillips COP finalized its acquisition of Marathon Oil Corporation late last year. The acquisition added more premium oil and natural gas resources to its portfolio, where the production costs are relatively low. This means COP is well-positioned to survive periods when the commodity prices turn low.

The upstream energy giant also anticipated significant cost synergies from the Marathon Oil takeover. Now the obvious question: Is the company actually witnessing all the benefits from the buyout? On the latest earnings call, ConocoPhillips revealed that it is doing better than expected from the takeover.

COP initially projected an annual cost synergy of $500 million from the Marathon Oil acquisition. However, during the second-quarter earnings call, it stated that it now expects to save more than $1 billion annually. COP is likely to realize this gain by the end of 2025, without needing to drill a single well. 

Investors should know that ConocoPhillips believes that it has acquired more valuable oil and gas resources from the Marathon Oil takeover than earlier estimated, thanks to the Permian, the most prolific basin in the United States.

CVX & FANG’s Solid Permian Footprint

Like ConocoPhillips, Chevron CVX and Diamondback Energy, Inc. FANG also have a significant presence in the Permian.

Chevron has a strong footprint in the Permian. With more than 2 million net acres of land, CVX has been operating in the basin for more than 100 years.

Diamondback Energy is a pure-play Permian operator. FANG has a huge inventory of oil and gas wells, thereby showcasing a solid production outlook.
