TriGen Proposes CO2-EOR for Mexico Mature Oil Fields, Adding Low-Carbon Barrels and CO2 Storage

TriGen Energy is proposing a model for Mexico's mature oil fields that combines pressurized oxy-fuel power generation with CO2-enhanced oil recovery. At the Mexico Oil and Gas Summit 2026, CEO Pieter Kapteijn said the approach could add 650 million to 820 million barrels of incremental crude across 15 PEMEX fields while storing 200 million to 250 million tonnes of CO2. Each site would also produce power, fresh water, and extend field life by 12 to 18 years. The proposal lands as PEMEX proven reserves have fallen roughly 40% since 2014. Mature fields already have wells, infrastructure, and reservoir data, which lowers the subsurface risk that usually slows new projects. TriGen estimates $2.5 billion to $3.5 billion in capital costs and says the main challenge is commercial structure, not technology. The company wants a consortium-based lighthouse project and regulatory flexibility to prove the model in Mexico.

The interesting part here is that they are treating CO2 as a revenue stream, not just a disposal cost. Pairing power generation with EOR and storage is the kind of integrated project that actually pencils out. But the 30% to 40% IRR estimate depends on carbon credits and clean power premiums holding up, so I would want to see the price assumptions.

Worth a read for anyone following CCUS. TriGen is pitching 200 to 250 million tonnes of stored CO2 across 15 PEMEX fields, plus a big chunk of incremental oil. That is real scale if it works. The catch is that none of it happens without a consortium deal and regulator buy-in, and Mexico has not exactly moved fast on either.

They claim steam turbines avoid gas turbine supply bottlenecks, which is fair, but 150 MWe per site is not huge. Also, oxy-fuel at 10,000 hours in EU pilots is still early for commercial duty. I would want to know the parasitic load for air separation and compression before trusting the net power and storage numbers.

The regulatory part is the real story. A single field selling power, water, oil, and carbon credits does not fit the existing permit structure. If Mexico wants this, it needs a framework that lets the project prove itself without a decade of rule changes. Otherwise the technology does not matter.

Not my usual beat, but the economics are worth comparing. They are claiming $2.5 to $3.5 billion CAPEX for 150 Mb/d and 200+ million tonnes of storage. That is a big upfront number for PEMEX. The question is whether the oil price and carbon credit assumptions survive contact with reality.

The article makes a decent case for mature fields as the fastest path to new barrels. Eight to twelve years for a new discovery versus using existing wells and infrastructure is a real advantage. The blue barrel label is marketing, but the CO2 storage math is worth following.
