GORE Amplified Geochemical Imaging service is:- a surface based- passive- geochemical method- Direct Hydrocarbon Indicator
It measures and maps- HC compounds from the soil gas in the sub part per billion range
It uses- Gore´s unique and highly sensitive passive diffusion module- advanced mathematical and statistical techniques to identify and analyze the microseepage signal
It creates- a comprehensive geochemical dataset that can be interpreted with various techniques (incl. AGI modelling)

NOTES & DEFINITIONSGeochemical Model: The geochemical difference in surface soil gas signature between
analogous production and background (dry) areas, as defined by groups of model set samples.
This model is used to classify membership of the survey grid samples based on the degree of
similarity to the geochemical signatures of 'production' and 'background'.
Probability Value: The percent probability that the surface geochemical character matches
that modeled over a producing reservoir(s); or in the case of a frontier survey, model set samples
which are selected as exhibiting petroleum-like character.
Anomalous Threshold: The modeled probability value at or above which the geochemical feature
is most likely indicative of petroliferous accumulations
Geochemical Feature: Any collection of contoured surface values which seem to exhibit a common
influence and which may include probability values above and below the anomalous threshold.
NOTE:This map illustrates a computer-generated contour surface of probability values calculated for each
sample location. Probability values are most accurate AT THE SAMPLED LOCATIONS. The contour
surface developed between the data points is an estimate of the probability and is subject to
uncertainty, which increases with distance from each sample location. Further resolution
of the contoured surface may be appropriate through additional soil gas sampling depending on
the end-use of the data.

Four possible mechanisms:1) Diffusion - gradient movement of dissolved gases2) Aqueous transport - movement in ascending water3) Continuous gas phase flow
Favoured mechanism:4) Microbuoyancy - transport in buoyant microbubbles
• Direct surface projection of reservoirs• Migration in the absence of faults• Rapid changes in surface anomalies as production

Gore Sampler (Module)
• Patented, passive, sorbent-based– Chemically-inert, waterproof, vapor
permeable– Direct detection of organic compounds– Sample integrity protected
• Engineered sorbents– Consistent sampling medium– Minimal water vapor uptake
• Time-integrated sampling– Minimize near-surface variability– Maximize sensitivity (up to C20)– Avoids variables inherent in instantaneous sampling
• Duplicate samples

Cluster Analysis
Identify geochemical similarities in data patterns
– Soil gas data grouped by clusters
Assumptions/Requirements- Identify & remove noisy variables
- Cluster structure isolates “petroliferous” vs “background” character
- Sufficient cluster membership to sample signal variance
- Clusters have subsurface geochemical meaning
