The PSR+ helps researchers bring the power and
non-destructive measurement capabilities of
spectroscopy to bear on the search for oil and gas
deposits by scanning and analyzing soil and vegetation.
Using an NIR spectroradiometer or spectrometer provides an
easy-to-use, rapid, and inexpensive tool for determining the
mineralogy of samples in the field for identifying petroleum and
gas bearing formations. The presence of oil and gas reservoir
seepage is usually found at the surface through detection of
trace concentration of gases (ethane or methane), mineral
alteration of soils, or changes to the spectral response in
vegetation.

Sites affected by hydrocarbon seepage can show mineral
alteration in the formation of calcite, pyrite, uraninite, magnetic
iron oxides, and sulfides, clay mineral alteration, and other
anomalies.

Vegetation can show an adverse effect from seepage in the
amount of chlorophyll in leaves. Reflectance properties of
vegetation in the VIS range are dominated by absorption at 660
and 680nm. Changes in chlorophyll concentration produce
spectral shifts near 700nm (the red edge). The red edge shifts
towards blue when chlorophyll is lost - an indicator for oil and
gas.

The
PSR+ delivers the following capabilities:
  • Spectral resolution 350—2500nm
  • UV/VIS/NIR full range, fast, one-touch scanning
  • Compact, lightweight and reliable with no moving parts
  • Autoexposure, autoscaling, and auto dark current shutter
  • Easy to set up anywhere
  • Long-term stability
  • DARWin SP Data Acquisition software captures spectra in
    ASCII format for use with third party software—no pre-
    processing required
  • EZ-ID software for rapid mineral identification in the field
    using the USGS and SpecMIn spectral libraries
  • Access through DARWIN to vegetation indices

Avoid the limitation and problems associated with sampling and
analysis by using SPECTRAL EVOLUTION's field
spectroradiometers and spectrometers for fast, non-
invasive/nondestructive research.

Mineral identification of Kaolinite using a PSR+ spectrometer with EZ-ID mineral identification software and the
SpecMIN mineral spectra library. Clay mineral alteration of smectite to kaolinite can be an indicator of
hydrocarbon presence in soil.
