| Evidence of hydrocarbon microseepage includes chemical, geobotanical, and mineralogical anomalies, as well as magnetic, radiation, or related geophysical anomalies. Surface geochemistry is a valuable extension to any exploration project when applied properly. Staging the exploration program so that samples are acquired judiciously is the most often prescribed survey practice. This minimizes cost while maximizes cost while maximizing sample placement. However, due to the noisy nature of geochemical data, staging sample collection can present some problems. Multiple reconnaissance surveys are acceptable to ascess the presence of an anomaly, but prior to drilling a detailed survey of closely spaced samples should be run in addition to reoccupying the reconnaissance sample locations. |
