| Abstract | The city of Tianjin and its surroundings is underlain by two Tertiary and two basement aquifers. At present, only the Tertiary aquifers are being exploited (20 Mt/yr) resulting in a pressure drop of 7 to 9 bars beneath the city; the useable energy produced is about l00MW th. The two Tertiary aquifers can be approximated by simple computer models whose permeability and compressibility were obtained by optimization and matching of observed pressure drawdown histories. Future behaviour of both aquifers has been assessed using variousabstraction and re-injection scenarios. |
