The Geothermal Resources and Potential in Hanoi Basin, Vietnam

Abstract

This report describes the geothermal resources and potential in Hanoi basin followed by the results of heat flow and subsurface temperature studies. The not small size 40 km  14 km of high heat flow anomaly with values more than 100 mW/m2 was detected in the southeastern part of the basin. The temperature at depth about 3000 m under this anomaly measured in the oil borehole is reached about 1400C - 1500C. This area is expected to the Pre-feasibility study for energy generation.
The geothermic measurements carried out in a large number of the shallow wells in the basin are indicated the stable range of temperature 25-260C from the depth 15 - 20 m to more than 100 m around year. It is noted that, the Hanoi basin is the biggest energy consumption area in Northern Vietnam. The hot time duration is often more than 8 months in every year with the temperature in the air varied from 300C to 380C, so the use of the ground sources heat pump (GSPH) for air conditioning systems can be expected as a measure for saving of the energy consumption.
