Crude Oil & Natural Gas (PE-1000, SP-3D, AMG-1)
Fossil fuels, natural gas, and crude oil contain high amounts of mercury.  The mercury must be removed to prevent problems such as corrosion of pipes in the purification process, in addition to the poisoning of catalysts in the electrochemical industry. For this reason, it is necessary to monitor the mercury concentrations of feedstock, even after mercury removal.....

Exploration of underground resources (EMP-2, MA-3000)
Since mercury is highly volatile; it shows a close correspondence with subterranean heat.  The mercury is utilized in geothermal prospecting and spring prospecting as a means of knowing the spread of geothermal activities and faults in geothermal fields. In addition, Earth/Science exploration utilizes mercury as an index element due to its effectiveness in iron deposit exploration.
