Active Soil Gas Surveys

CO Geosciences has teamed up with GCHEM Ltd to offer an active soil gas survey, aimed at finding buried uranium deposits. Like radon, helium, hydrogen and other soil gas anomalies can be associated with buried uranium deposits.

Since 1997, GCHEM’s geoscientists have collaborated with academia, industry and government agencies throughout Western Canada to develop and apply new technology in solving oil-field related surface geochemistry problems.  GCHEM specialize in the measurement and detection of light alkanes/alkenes (C1 to C5 and C6+) N2, O2, He, H2, CO2. Results are measured in parts per million (ppm) or 100% type levels.  GCHEM have the second largest commercial stable isotope lab in the western hemisphere.

Samples are collected by CO Geoscience and analyzed at GCHEM’s laboratory, located in Lloydminster, AB.  In-house analytical facilities include five high resolution gas chromatographs.

Pilot hole for soil gas probe being drilled

The basic sampling methodology is:

  1. Drill a hole using a battery powered drill with a specialized drill bit to approximately 1 m.
  2. Insert a soil gas probe.  Isolate bottom of hole from surface and allow to stabilize for 48 hours.
  3. Collect a soil gas sample and contain it in evacuated glass sample vial.
  4. Ship samples to GCHEM’s laboratory.

*Mobile GC units and accredited technical staff are available for on-site, real-time analysis.
