February 2025 – In a move that cements its position as a leading force in the U.S. shale industry, ConocoPhillips (NYSE: COP) has successfully completed its acquisition of Marathon Oil, adding substantial, high-quality, low-cost-of-supply inventory to its already dominant unconventional asset base. This acquisition is expected to unlock significant operational synergies, boost shareholder returns, and strengthen ConocoPhillips’ production portfolio.
Strategic Importance of the Acquisition
The Marathon Oil acquisition is more than just a bolt-on asset purchase—it is a transformational deal for ConocoPhillips’ Lower 48 operations. Marathon Oil’s assets complement ConocoPhillips’ existing holdings in key U.S. shale basins, primarily:
- Permian Basin
- Eagle Ford Shale
- Bakken Formation
By acquiring Marathon Oil, ConocoPhillips has expanded its production base, secured long-term development opportunities, and reinforced its capital-efficient operations.
Production Growth & Asset Synergies
Following the acquisition, ConocoPhillips’ Lower 48 production has increased to 1.308 million barrels of oil equivalent per day (MBOED) in Q4 2024, with Marathon Oil’s assets contributing approximately 394 MBOED on a proforma full-year basis.
Breaking down the numbers:
- Q4 2024 total production: 2.183 MBOED
- Full-year 2024 production: 1.987 MBOED
- Marathon Oil’s contribution (Q4 2024 only): 126 MBOED
With this acquisition, ConocoPhillips now holds one of the strongest unconventional portfolios in North America, reinforcing its dominance in the Lower 48.
Financial Impact & Cost Synergies
ConocoPhillips has outlined an aggressive integration strategy that will deliver more than $1 billion in run-rate synergies by the end of 2025. Over half of these cost savings are already incorporated into the company’s 2025 capital spending plan of $12.9 billion.
Additionally, the company is prioritizing returning capital to shareholders, with a planned $10 billion return in 2025 through dividends and share buybacks. This move aligns with ConocoPhillips’ long-standing commitment to delivering value to investors while maintaining financial discipline.
Strengthening Balance Sheet & Debt Optimization
To support the acquisition, ConocoPhillips restructured its debt portfolio, extending maturities and optimizing interest rates. This step ensures that the company can absorb the acquisition without compromising its financial flexibility.
Moreover, the company has advanced its previously announced $2 billion non-core asset disposition plan, with $0.6 billion in Lower 48 asset sales already signed and expected to close in the first half of 2025. These sales will help streamline operations and provide additional capital flexibility.
What This Means for the U.S. Energy Market
The acquisition of Marathon Oil underscores a broader trend of consolidation in the U.S. oil and gas industry, particularly in shale plays. As companies seek to drive efficiency, reduce costs, and maximize shareholder returns, scale has become a key differentiator.
For ConocoPhillips, the deal strengthens its ability to compete with industry giants like ExxonMobil and Chevron, both of whom have made major acquisitions in recent years.
Looking Ahead
With a clear roadmap for integration and value creation, ConocoPhillips is set to leverage its expanded asset base for sustained production growth and enhanced free cash flow generation. The focus remains on operational efficiency, disciplined capital allocation, and strong shareholder returns.
The Marathon Oil acquisition is a strategic win for ConocoPhillips, solidifying its status as one of the leading independent exploration and production companies in the world. As the energy landscape evolves, this deal positions the company for long-term success in the ever-competitive oil and gas sector.
