The Carbon Capture and Sequestration Portfolio from Occidental Petroleum feels very physical long before anyone mentions tonnes of CO?. You picture thick steel pipelines disappearing into scrubland, block valves humming quietly, and injection wells breathing in exhaust gas that would otherwise hang above Houston and Los Angeles.

What this CCS portfolio offers

Occidental Petroleum’s Carbon Capture and Sequestration Portfolio groups saline formations and depleted reservoirs along the U.S. Gulf Coast that are engineered for long-term CO? storage. These storage sites are tied into existing pipeline networks, giving refineries, power plants and factories contracted routes to bury their emissions underground.

The company markets the portfolio around multi-decade storage capacity, measured in millions of tonnes of CO?, and structured service contracts rather than one-off projects. For industrial emitters, that translates into predictable fees per tonne and clear monitoring obligations that continue long after the last molecule has been injected.

How it works in practice

In a typical use case, CO? is captured at an industrial site, compressed to a dense fluid and pushed through pipelines to Occidental’s designated sequestration hub. There, injection wells drive the CO? into deep rock layers more than a kilometer below ground, under seals designed to keep it locked away for centuries.

Chief executive Vicki Hollub has repeatedly framed this portfolio as a foundation for Occidental’s broader low-carbon strategy, sitting alongside its planned Direct Air Capture plants. For a plant operator signing up, the haptic reality is simple: metered pipeline connections, fenced well pads, and data screens tracking pressure, temperature and flow every hour.

Where CCS stands today

The portfolio sits inside Occidental’s Oxy Low Carbon Ventures arm, which focuses on carbon management solutions and new business around captured CO?. The group highlights that sequestration projects can support customers seeking compliance with future U.S. federal and state emissions rules, not just voluntary climate targets.

Regulatory frameworks such as U.S. EPA Class VI well permits and monitoring requirements form a key part of the pitch. Operators know they are not just buying storage space, but a regulated system of baseline tests, seismic checks and long-term surveillance promising detailed records for auditors and regulators.

The feel on the ground

Walk up to a sequestration site and the first impression is quiet order rather than drama: gravel crunches under boots, stacked pipe sections lie in neat rows, and the only movement comes from pump skids and a distant flare. Screens in the control room show subdued graphs instead of trading charts, with each curve tracing pressure changes deep beneath the surface.

For engineers like a project manager at Oxy Low Carbon Ventures, this is everyday infrastructure: K-braces, flange bolts, corrosion checks. For a visiting customer, the tactile experience of grabbing a warm pipeline insulation jacket can make the abstract idea of carbon risk suddenly very real.

Risks, limits and economics

Economically, the portfolio leans on tax incentives such as the U.S. 45Q credit, which pays for every tonne of CO? permanently stored in geological formations. That helps narrow the cost gap between traditional emissions and managed sequestration, though project economics still hinge on scale and stable policy.

Geological risk, long-term liability and community acceptance all sit in the background. Occidental addresses them with site selection, public consultation and detailed risk assessments, but no CCS project is completely free of controversy or technical challenge.

Company context and shares

Occidental Petroleum uses its Carbon Capture and Sequestration Portfolio to position itself as an oil and gas producer with a long-term carbon management strategy. The initiative complements conventional upstream operations in the Permian Basin and other regions where the company already manages large CO? flows. Occidental Petroleum shares (ISIN US6745991058) trade on the New York Stock Exchange in U.S. dollars.
