Building technologies for permanent carbon dioxide removal through in-situ mineralization

About GeoTek Carbon

At Geotek Carbon, we are developing durable, science-backed carbon storage by harnessing the natural reactivity of volcanic rocks. Using advanced geologic mapping, geophysical surveys, and petrographic analysis, we identify and characterize mafic and ultramafic formations with high potential for CO₂ mineralization.

We then deploy our drilling expertise to access these reactive horizons and inject CO₂-rich water deep underground, where it rapidly transforms into stable carbonate minerals locking carbon away for thousands of years.

OUR PROCESS

THE JOS PLATEAU. A NATURAL CARBON SINK

Our first deployment is focused on the Jos Plateau, a region uniquely suited for mineralization because of its extensive younger and older basalt flows. The Jos Plateau is a volcanic highland underlain by alkaline olivine basalts, rich in magnesium, calcium, and iron. These elements readily bind with dissolved CO₂ to form solid minerals like magnesite and calcite.

Map & Model

Satellite imagery, geophysics, and field mapping to locate and assess target basalts.

Validate Reactivity

Thin-section petrography and geochemistry to confirm mineral content and carbonation rates.

Drill & Complete Wells

CO₂-compatible well designs with multi-barrier protection and monitoring.

Verify Permanence

Transparent MRV aligned with global CDR standards to ensure >1,000-year storage.

OUR WORK: FROM BASALT MAPPING TO CARBON MINERALIZATION

We have completed full geophysical coverage of the Plateau, integrating satellite imagery, magnetic surveys, resistivity profiling, and seismic lines. Each basalt flow has been sampled, analyzed, and classified for CO₂ reactivity, creating a detailed map of carbon sequestration potential.

Mapping the Opportunity

In Kassa, CO₂-rich water injection into basalt produced expected pH changes and early carbonate precipitation, confirming rapid mineralization in West Africa.
