The risks of long-term re-injection in supercritical geothermal systems
Francesco Parisio,Francesco Parisio,Víctor Vilarrasa,Wenqing Wang,Olaf Kolditz,Olaf Kolditz,Thomas Nagel,Thomas Nagel +7 more
TL;DR: It is shown that thermally-induced stress and strain effects dominate the geomechanical response of supercritical systems compared to pore pressure-related instabilities, and greatly enhance seismicity during cold water re-injection.

TL;DR: The Los Humeros Volcanic Complex (LHVC) as mentioned in this paper is a large silicic caldera complex in the Trans-Mexican VOLCANIC Belt (TMVB), hosting a geothermal field currently in exploitation by the Comision Federal de Electricidad (CFE) of Mexico, with an installed capacity of ca. 95 MW of electric power.

Nonlinear conjugate gradients algorithm for 2-D magnetotelluric inversion
William Rodi,Randall L. Mackie +1 more
TL;DR: In this article, a nonlinear conjugate gradients (NLCG) algorithm was proposed to minimize an objective function that penalizes data residuals and second spatial derivatives of resistivity.

Petrology of Philippine geothermal systems and the application of alteration mineralogy to their assessment
TL;DR: In this article, neutral-pH alteration is divided into four zones on the basis of key clay minerals, and two subzones are defined by calc-silicates, and the four main zones of acid alteration are: kaolinite (ambient to 120°C), dickite ± kaolite (120, 200, 200) and pyrophyllite ± illite (230,320°C).

Geological noise in magnetotelluric data: a classification of distortion types
TL;DR: An extension of the decomposition technique is presented that allows for a departure from the purely two-dimensional case for regional structures and dimensionality parameters are suggested which include conventional and regional skew as well as local and regional structural dimensionality indicators.
Understanding the resistivities observed in geothermal systems
TL;DR: In this paper, the authors reviewed the factors affecting resistivity in geothermal systems and found that conductive clay products of hydrothermal alteration are the most common cause of low resistivity.
