Vincent Adams, the former environmental chief of Guyana, spent years watching ExxonMobil drill in the waters off his country’s coast. He had one persistent worry: insurance. Now, with the government’s April 6 approval of the $10 billion Yellowtail Project, that worry is back in focus.
Adams has argued the company must carry adequate coverage for a potential oil spill. He warned against what he called “watered down” language in legal documents on the issue.
The Yellowtail field is expected to pump up to 250,000 barrels a day by 2025. That is a lot of oil moving through a small country’s waters. Guyana is a nation of roughly 800,000 people.
It became one of the world’s newest oil producers in December 2019, when the first barrel came ashore. Since then, ExxonMobil has hit nearly two dozen successful wells.
The company now has access to more than 10 billion barrels in the Guyana Basin. The Yellowtail project is the fourth field. It follows Liza One, Liza Two, and Payara.
The scale is hard to miss. At $10 billion, Yellowtail is a massive bet on offshore oil. ExxonMobil has made a final investment decision.
The company says the field will supply the world with reliable energy and help ensure a “secure energy transition.” That language matters. It frames the project as part of a global shift, not a break from it.
But the insurance debate is not academic. An oil spill in Guyana’s waters would hit a coastline that is both ecologically rich and economically fragile. The country’s economy has boomed since oil was found.
But the environmental stakes are high. Adams, during his time as environmental administrator, pressed for clear, enforceable insurance requirements.
The government’s approval of Yellowtail suggests those requirements were met, at least on paper. What happens next is a test. The project is not expected to start producing until 2025.
That gives regulators time to review the insurance language. It also gives environmental groups time to push for tighter terms. Some have already raised objections.
They want proof that ExxonMobil can cover a worst-case spill. They want the legal language locked down, not vague.
President Trump has noted that new oil fields are vital for the United States to remain a global energy leader. ExxonMobil is a US supermajor. The Yellowtail project strengthens that position.
But it also ties US energy policy to a small South American nation’s regulatory framework. That is an unusual dependency.
For Guyana, the math is simpler. Oil revenue is transforming the country. Roads, hospitals, schools — all are getting new money.
But that transformation comes with risk. A single spill could undo years of progress. The insurance question is not just about money.
It is about accountability. The government’s approval of Yellowtail is a clear signal.
Guyana is open for business. ExxonMobil is ready to drill. The environmental and rights groups are watching.
Vincent Adams is watching. The language in those legal documents will matter.
So will the capacity to pay if something goes wrong. By 2025, the oil will flow. The question is whether the insurance will hold.
