Geoengineering, geological engineering, or geotechnical Engineering deals with the discovery, development, and production and use of earth resources, as well as the design and construction of technologies to harvest these resources, change weather patterns and thus reverse negative effects of other technologies.
Geoengineers work in areas of
(1) mining, including surface and subsurface excavations, and rock burst mitigation;
(2) energy, including hydraulic fracturing and drilling for exploration and production of water, oil, or gas;
(3) infrastructure, including underground transportation systems and isolation of nuclear and hazardous wastes; and
(4) environment, including temperature changes, reduction of CO2 and other gases in the atmosphere, groundwater flow, contaminant transport and remediation, and hydraulic structures.
