A fault-controlled geothermal system in Tarutung (North Sumatra, Indonesia)investigated by seismological analysis
… which appear to be associated with the three big geothermal manifestations in Sipoholon, Hutabarat, and Panabungan area. These anomalies are connected with high Vp/Vs and low Qp anomalies below the Tarutung basin at depth of around 3 - 10 km. This suggests that these geothermal manifestations are …

Numerical modelling of the shallow reinjection and tracer transport at Nesjavellir Geothermal System, Iceland : an assessment of heat transfer and fluid flow
The Nesjavellir geothermal power plant is the second largest in Iceland, with a district heating capacity of 300 MW and electrical generation of 120 MW. Reinjection of the excess water from the Nesjavellir geothermal plant, derived from separated water from high enthalpy wells and condensed steam, …

3D conceptual and TOUGH2 modelling of the Waiotapu geothermal field, New Zealand
The Waiotapu geothermal system is a liquid dominated, high-temperature system located in the Taupo Volcanic Zone (TVZ) in the North Island of New Zealand. Seven exploration wells were drilled in Waiotapu in the late 1950s, which are drilled to around 500 m - 1100 m depth. Although Waiotapu has …

3D Modelling of Faulting and Intrusion of the Nevado del Ruiz Volcano, Colombia
… of Colombia. The area has been evaluated for its geothermal potential for the past decade. Geothermal energy, once implemented, has been proven to be a stable source of baseload energy. However, geothermal projects are often classified as high-risk since geothermal prospects maintain uncertainties …
