112. Thermo- and petrophysical rock properties of the Los Humeros geothermal field (Mexico): comparison of outcrop analogues and reservoir formations

Mrs Leandra Weydt (TU Darmstadt)

Topic 2: Exploration of Geothermal Reservoirs

Oral

The Los Humeros geothermal system is an operating steam dominated field with 65 wells (23 producing). With temperatures above 380 °C, the system is characterized as a super-hot geothermal system (SHGS). The development of such systems is still challenging due to the high temperatures and aggressive reservoir fluids, which lead to corrosion and scaling problems.
For better reservoir...

161. Spectral analysis of aeromagnetic data for geothermal exploration and assessment: the case of southern Italy

Topic 2: Exploration of Geothermal Reservoirs

Oral

The best way to study the subsurface geothermal potential is by directly measuring the heat flow and temperature from boreholes. However, heat flow and temperature data are not uniformly distributed and not consistently deep; thus they are not enough in inferring deep thermal distributions. In this case, Curie depth isotherm may provide the deep thermal distribution which cannot be obtained...

101. Characterization of a Geothermal Reservoir in Denmark based on Seismic Inversion Results

Dr Runhai Feng (Department of Geoscience, Aarhus University)

10/9/19, 11:55 AM

Topic 2: Exploration of Geothermal Reservoirs

Oral

The geophysical characterization of reservoir properties, such as lithofacies, porosity and other petrophysical variables, is essential for the exploitation of subsurface reservoirs. Indeed, reservoir lithofacies classification provides significant information about the petrophysical behavior of reservoir rocks and their degree of compartmentalization (Bosch et al., 2002). Furthermore, the...

121. Seismicity induced during thermal and hydraulic stimulation of the well GRT1 at the Rittershoffen deep geothermal site, France

Rike Köpke (Karlsruhe Institute of Technology)

10/9/19, 12:10 PM

Topic 2: Exploration of Geothermal Reservoirs

Oral

In a geothermal reservoir, seismicity may be induced due to pressure changes in the underground as a result of drilling, stimulation or circulation operations. The induced seismic events are therefore strongly linked to the fluid flow and the geological structures that make this fluid flow possible. The development of the deep geothermal site at Rittershoffen (Alsace, France) was monitored...
