Publication year 2014 Abstract We investigated the impact of the exploitation of a geothermal well doublet on surface movement. We found that the largest effect should be expected from the progressive cooling of the reservoir, through the thermo-elastic coupling. The absolute value of the expected subsidence is low, but possibly measureable if circumstances are favourite. In that case the distribution of the subsidence can be used to obtain knowledge about the distribution of the cooled part of the reservoir. In addition, the shape of the subsidence pattern gives information about the subsurface parameters like the elastic profile. In particular when measurements of horizontal displacements are available alongside vertical displacement, this information can be used in an inversion exercise to constrain the profile of the elastic modulus. A proper monitoring strategy will help to optimize the information to be obtained.
