In this case history, the client conducted a soil gas hydrocarbon survey along the trace of the seismic line to look for evidence of hydrocarbon microseepage from a seismically defined trap at CDP 1070 ([[:file:surface-geochemical-exploration-for-petroleum_fig18-6.png|Figure 1]]). Propane soil gas anomalies were detected at CDP 1070 and 1096. The wildcat well drilled at CDP 1070 resulted in a new field discovery. The geochemical lead at CDP 1096 was reevaluated seismically. After additional processing, a revised interpretation (right) also predicted [[porosity]] development there and coincident with the surface geochemical anomaly. A second productive well was drilled at CDP 1096.

This is a good example, illustrating how we can use surface geochemical data to evaluate a geophysical lead and a geochemical lead.
