Why Exxon and Chevron are fighting so hard over an oil project in Guyana

🗞️ Driving the news: ExxonMobil and Chevron are locked in a high-stakes arbitration over a multibillion-dollar oil project in Guyana, with proceedings commencing this week in London
• The dispute stems from Exxon’s claim that it has a contractual right to pre-empt Chevron’s $53 billion acquisition of Hess, which includes a 30% stake in the Stabroek Block — one of the world’s most lucrative new oil fields

🔭 The context: Guyana’s offshore oil discoveries have positioned it as a global energy hotspot, with Exxon-led production currently reaching 650,000 barrels per day and expected to double by 2027
• Exxon, Chevron, and Cnooc form the consortium developing the block
• Exxon contends it has first refusal rights over any Hess stake sale, while Chevron and Hess argue this clause does not apply to corporate-level mergers
• The outcome could determine the future composition of one of the most valuable upstream portfolios in decades

🌍 Why it matters for the planet: Guyana’s deepwater oil boom presents a paradox: it offers low-cost, low-carbon intensity crude, but also risks deepening fossil fuel dependency during a critical decade for climate mitigation
• The project’s development has also intensified geopolitical tensions, including Venezuela’s territorial claims
• A shift in ownership could alter operational dynamics, environmental standards, and stakeholder accountability in a region undergoing rapid transformation

⏭️ What's next: A private arbitration panel will decide by late summer whether Exxon and Cnooc can override Chevron’s Hess acquisition
• A Chevron win could consolidate its upstream future and narrow the gap with Exxon, while a loss may force it to abandon the deal after nearly two years of strategic limbo
• The decision also holds implications for global M&A activity in the energy sector, investor confidence, and the evolving power dynamics among oil majors

💬 One quote: "What it highlights is how valuable big, low-cost oil fields really are in a world where it’s getting harder and harder to find them," — Dan Pickering, Chief Investment Officer at Pickering Energy Partners

📈 One stat: The Stabroek Block in Guyana holds an estimated 11 billion barrels of recoverable oil and gas—making it one of the largest offshore finds globally in the past decade
