Spatiotemporal Geochemical Hydrocarbon testing...Yes SGH is what has the market in a tizzy. It is a useful tool that has been used by Great Bear to help define drill targets at Dixie Creek. It has also been used by BTU (and others) to the south of the GBR Dixie. A scale of prospectivity from 0-6 is used. In the case of GBR the scale of prospectivity was a 5.5 out of 6. For DG the scale is 4 out of 6. BTU also used SGH to define thier drll targets and so far drlled 7.8m of 2.27%cu. It s a useful tool but not an end all, be all.
