Gas geochemistry in modeling geothermal reservoirs [PDF]
Geofísica Internacional, 2002 Geochemical models for Los Azufres and Los Humeros geothermal reservoirs are discussed. Los Azufres is defined as vapour-liquid (VAP-LIQ) and Los Humeros is mainly a vapour-dominated field.

The los Azufres, Mexico, Geothermal Reservoir: A Case History
Brazilian Journal of Geophysics, 2023 Los Azufres is the second geothermal reservoir that has been developed in Mexico. It is located in the Mexican Volcanic Axis, about 90 km East of the city of Morelia, the capital of the state of Michoacán. The field sits atop the Sierra de San Andrés range, covering about 30 km².

Variation of gaseous species concentration in the Los Azufres geothermal wells as a tool to study the reinjection effect [PDF]
Geofísica Internacional, 2002 Since 1982 the concentration of gaseous species (CO2, H2S, CH4, N2, H2, Ar, and He) has been monitored periodically in the Los Azufres geothermal field, Mich., Mexico by CFE.

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 11, November 2023., 2023 Abstract Over the past decade, we have conducted geochemical and isotopic monitoring of the fumarolic gases of the Peteroa volcano (Argentina‐Chile). Using the resulting data set, we constructed a conceptual model that describes the evolution of the magmatic‐hydrothermal system and identifies precursory geochemical signals of the last eruption.

Earth's Future, Volume 11, Issue 10, October 2023., 2023 Abstract The availability of freshwater from glaciers and snowmelt is of vital importance for people and ecosystems in the context of global climate change. Here, we focus on 25 glaciers located in different climates and latitudes and investigate their recent (1958–2020) and future projected trends (2020–2050 and 2070–2100) in monthly precipitation (Pr)

Geophysical Research Letters, Volume 50, Issue 10, 28 May 2023., 2023 Abstract We report the first detection of unrest at Socompa volcano during our recent survey of Central Andean volcanos in Northern Chile using Interferometric Synthetic Aperture Radar measurements spanning January 2018 to October 2021. We find that Socompa volcano, whilst initially undeforming and no recorded eruptions for 7.2 kyr, shows a steady ...

Comparison of measured and simulated pressure and temperature profiles in geothermal wells [PDF]
Geofísica Internacional, 1999 The correct application of geothermal wellbore flow simulators is a useful tool since their adequate calibration and use often avoids the need to perform costly experimental PTQ logs inside geothermal wells. Two existing wellbore flow simulators, GEOPOZO

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 12, December 2022., 2022 Abstract Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions. In this study, we address a fundamental question, namely, how do subduction zones and volcanic arcs respond to the subduction of “atypical” oceanic lithosphere.

Resource competition explains rare cannibalism in the wild in livebearing fishes
Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022 We assessed the occurrence of cannibalism in mosquitofishes (genus Gambusia) and guppies (Poecilia reticulata) by examining 17 species (11,946 individuals) across 189 populations in the wild, and by conducting a mesocosm experiment for one species (Gambusia affinis).

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 2, February 2022., 2022 Abstract We report on new volcanic gas composition results acquired in October 2017 at Minas de Azufre, a persistent fumarolic field topping the resurgent Sierra Negra caldera, in the Galápagos archipelago. Our results indicate that the Minas de Azufre fumaroles are moderately hydrous (52–64 mol.% H2O) and rich in CO2 (35–46 mol.%), with total sulfur ...
