Guyana weighs Stabroek Block split as oil costs clear early

The Stabroek Block consortium has recouped $55 billion in costs early, changing Exxon’s Guyana oil bookings and cash-flow outlook.

$55 billion recovered early

The production-sharing contract with Guyana allowed Exxon and its partners to use as much as 75% of oil output to recover exploration and development spending. After those costs are recovered, the consortium and Guyana split profit oil evenly under the contract.

Neil Hansen, Exxon’s chief financial officer, said the accumulated investment since 2014 was recovered about two years sooner than the company had expected. Hansen attributed the timing to the pace at which the Stabroek Block was developed.

Exxon will now book about 100,000 fewer barrels per day from Guyana as it enters the third quarter, Hansen said. He also said free cash flow from the country is expected to reach twice its 2025 level by 2030, even as reported barrels decline.

Partners reset Guyana exposure

Exxon operates the Stabroek Block with a 45% interest, giving it the largest share of the consortium’s production and cash flows. Chevron holds 30% after acquiring Hess, the original partner in the venture, while Chinese oil company CNOOC owns the remaining 25%.

The structure means the cost-recovery milestone affects three companies at once, but not in equal proportions. Exxon has the operating role and the largest economic exposure; Chevron has inherited a major Guyana position through Hess; CNOOC remains the smaller partner by stake.

The consortium’s next two projects, Uaru and Whiptail, are expected to begin production this year and next year, respectively, according to Exxon. Those startups would add new producing phases to a block that has already moved quickly from discovery and development spending into cost recovery.

Darren Woods, Exxon’s chief executive, said during the company’s second-quarter earnings call that Guyana still offers more exploration room. He said Exxon has used artificial intelligence to review drilling and subsurface data, adding: “We're not done yet in Guyana and we continue to see a really bright future there.”

Border dispute limits acreage

A portion of the Stabroek Block remains under force majeure due to a maritime border dispute between Guyana and Venezuela. The matter is awaiting a ruling by a United Nations court, leaving part of the acreage outside normal development planning.

Guyana’s oil boom has also moved faster than the country’s domestic infrastructure. The country has about 1 million people, and residents continue to face prolonged electricity blackouts and weak infrastructure even as many local businesses benefit from the oil cycle.

The economic challenge is now shifting from attracting oil investment to managing it. Guyana’s government faces the task of using petroleum revenue without allowing the rest of the economy to become too dependent on one export sector.

Three Stabroek paths emerge

If Uaru and Whiptail start on the timetable described by Exxon, the block would add more offshore supply and strengthen Guyana’s role among newer oil producers. For Exxon, that path would support the company’s cash-flow target; for the industry, it would reinforce deepwater Guyana as a lower-cycle-time province.

If the border dispute constrains more acreage or delays exploration, the macro effect would be smaller future supply from a fast-growing basin. Exxon would face a narrower inventory of near-term drilling options, while rivals and service companies would have less visibility on Guyana-linked activity.

If Guyana’s infrastructure constraints persist, the pressure point would move from the offshore reservoirs to the onshore economy. In that scenario, national growth could become harder to balance, Exxon would face closer scrutiny of its local footprint, and the wider sector would have to show that rapid oil development can coexist with broader economic gains.
