02The method

Helium surveying — listening to the Earth’s invisible signals

Helium migrates naturally from deep within the Earth. Measuring tiny variations of helium at the surface maps deep geological processes, points to energy and mineral resources, and identifies areas of increased geological activity.

  1. 1Survey designSurvey area and measurement grid planned around the objectives — regional profiles at 250 m spacing, detailed grids of 100 × 100 m.
  2. 2Field measurementsHelium concentration measured in soil gas at each point, with GNSS positioning — up to thousands of points per day.
  3. 3Data processingData filtered, background variations removed and helium concentration maps produced.
  4. 4Target analysisAnomalies analysed for shape, size and continuity; additional profiles and detailed grids over the most promising zones.
  5. 5IntegrationHelium anomalies integrated with 2D/3D seismic, geological and structural data to define targets and depth of source.
Helium surveying workflow: survey design, field measurements, data processing, target analysis and integration with seismic
Helium surveying — from survey design to an integrated interpretation with 2D/3D seismic.

Fast

Thousands of points per day; a full project in weeks to months.

Cost-effective

Significantly lower cost than seismic surveys, with a high return of information.

Low impact

Non-invasive, lightweight equipment; easy to permit; works in remote and sensitive areas.

Multiple uses

Hydrocarbons, natural hydrogen, critical minerals, and seismic and volcanic risk assessment.
