Pangaea's Gas-Sieve™
Geochemical Surveys
Pangaea's
gas-sieve technology is an important advancement for geochemistry.
Thermogenic gases migrate to the surface in trace concentrations
making it difficult to capture quality data. Not only does the gas-sieve
concentrate
the soil vapor sample by 500 times over conventional methods the
sampling interval is only 4 minutes. This active adsorbent
collection method increases sampling efficiency, reducing the time crews
spend in the field by 50-75% over passive sampling methodologies.
This decreases project costs substantially.
C1-C18
Hydrocarbon Soil Vapor Surveys
Soil
vapor is actively drawn across the gas-sieve and then analyzed for over
90 hydrocarbon compounds establishing a sophisticated hydrocarbon fingerprint.
Dry locations have a distinctly different fingerprint than
producing locations. These hydrocarbon models are then used in
adjacent areas to predict drilling potential. When a basin is
unexplored, other modeling reveals prospectivity.
C1-C11
Light
Hydrocarbon Soil Vapor Surveys
Soil vapor, collected at 4-8' BGL onto a gas-sieve is analyzed for
hydrocarbon composition and concentration and used to define the
hydrocarbon fingerprint. The C1-C11 data is a more economical
analytical suite than C1-C18, and does not compromise the interpretive
value of the data.
This is the most commonly requested and cost effective survey.
Permafrost
Core Surveys
Frozen 30" permafrost cores are collected and degassed onto a
gas-sieve for analysis.
These surveys are performed
in winter in areas without summer access.
Off-Shore
Piston Core Surveys
Piston
cores are collected and analyzed for
hydrocarbons utilizing the gas-sieve.
