Modelling of Subsidence in Geothermal Fields
Reservoir compaction and overburden subsidence are of concern in geothermal reservoirs. Pore pressure reduction due to geothermal production results in an increase in effective stress in rock matrix and induces compaction. The cumulative effect of compaction appears at the ground surface as subsidence which can result in potential hazards, financial, socio-economic and environmental problems.
