Offshore freshened groundwater

The resource hiding in plain sight

99% of all liquid fresh water on Earth is underground. Vast aquifers extend beneath continental shelves worldwide — precisely where the oil and gas industry has been for 70 years.

Deep groundwater layers discharge under a continental shelf. Wells can be drilled with an offshore rig and developed via offshore platform. Produced water is transported to land through pipeline.

What it is

A mapped resource, not a discovery

  • Deep aquifer reserves identified on every continent — many extending offshore under continental shelves
  • The O&G industry has 70 years of seismic data and well records covering these exact zones
  • ATLA partners with TGS — the world’s leading seismic company — for access to their global database
  • Standard offshore methodology applies: seismic interpretation, well planning, drilling, subsea infrastructure, offshore production, and pipeline or tanker delivery to shore
  • Rechargeable aquifers developed within their natural replenishment rate
Petroleum expertise

The technology crossover is direct

Seismic interpretation, well engineering, offshore drilling, subsea infrastructure, and FPSO operations are ATLA’s founding team competences — accumulated across 100+ years of combined offshore experience. The technology crossover to freshwater is direct and immediate: the tools, the methods, and the expertise are identical. Only the commodity changes.

Source Cost / m³
Bottled / trucked$2.00–$5.00
Desalination (avg)$0.50–$1.50
Desalination (best-in-class)~$0.50
Offshore freshwater (est.)$0.30–$0.80
Onshore groundwater$0.05–$0.20

Lower infrastructure cost means more communities can afford connection.

Sustainability

Developed within natural limits

Rechargeable by nature

Deep aquifers are naturally recharged. Developed within replenishment rates, they are sustainable long-term water sources.

Lower energy than desalination

No energy-intensive reverse osmosis. Natural aquifer pressure drives production, significantly reducing both cost and carbon intensity.

ESG-aligned

Aligns with EU taxonomy, UN SDG 6 (clean water and sanitation), and Horizon Europe climate criteria.

This is the resource.
