OUR PROCESS

From capture to carbonate: How Geotek Turns CO₂ Into Rock — Safely and Permanently. We combine safe engineering, rigorous monitoring, and proven geology to ensure every tonne of CO₂ injected becomes solid mineral for millennia.

The striking contrast between the deep turquoise water and the earthy hues of yellow, brown, and gray creates a visually captivating scene. The pool appears to be a hot spring or fumarole, typical of geothermal landscapes.

CO₂ Supply

Sourced from local industrial emitters and stored in pressurized tanks. For pilots, we use certified food- or industrial-grade CO₂ cylinders.

Dissolution

CO₂ dissolved in water under pressure for rapid reaction and safe underground delivery.

Injection

Wells with CO₂-resistant casing and cements, isolated from potable aquifers, monitored in real time.

Mineralization

Carbonated water reacts with olivine and pyroxene, releasing Mg²⁺ and Ca²⁺, forming stable minerals like magnesite and calcite.

Monitoring (MRV)

Groundwater sampling, tracer tests, and geochemical analysis to verify permanent storage.

THE JOS PLATEAU: AFRICA’S NATURAL CARBON BATTERY

The Jos Plateau in central Nigeria is a reactive carbon sink in waiting. Its younger and older basalt flows, enriched in olivine, pyroxene, and plagioclase, have one of the most favorable chemistries for CO₂ mineralization globally.

We have mapped the entire Plateau, producing the first Carbon Sequestration Geologic Atlas. It identifies injection targets, monitoring zones, and groundwater protection areas.

Basalt Rich in Reactivity

High MgO and CaO content makes these rocks ideal for binding CO₂ into stable carbonates. Fractured flow tops and vesicular zones allow injected CO₂-rich water to circulate and react. (Image: Olivine-rich thin-section; vesicular basalt face)

Mapped to the Millimeter

Kassa Field: 6 wells into younger basalt; rapid mineralization indicators.

Bukuru Basin: 4 monitoring wells; high-reactivity olivine basalt confirmed by XRD.

Riyom Ridge: Geophysics reveals deep, unfractured basalt with large-scale storage potential.
