Dynamics of fluid and heat flow in a CO2-based injection-production geothermal system
Binary system CO2-water displacement Heterogeneity Preferential flow
2018/3/23
CO2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO2 geological sequestration. Here, a 3-D, “two-spot” pattern wel...
Reconstruction of deep fluid chemical constituents for estimation of geothermal reservoir temperature using chemical geothermometers
High temperature geothermal fluid Multi-component geothermometer optimization Geothermal gases Analogue
2018/3/23
his paper elaborates the chemical constituent change principles of deep geothermal fluid during the process of upward movement. It summarizes research methods of hydrochemistry, isotope and numerical ...
In search of evidence of deep fluid discharges and pore pressure evolution in the crust to explain the seismicity style of the Umbria-Marche 1997-1998 seismic sequence (Central Italy)
fluid geochemistry/seismicity porepressure field Umbria-Marche 1997-1998 seismic sequence
2015/9/30
Starting soon after the first main-shocks of the long seismic sequence which has occurred along the Umbria-Marche boundary since September 1997, fluid geochemistry surveying was accomplished (around 2...
Fluid geochemistry and seismic activityin the period 1998-2002 at Turrialba Volcano (Costa Rica)
volcanic gases volcanic hazard geochemical monitoring geophysical monitoring Turrialba Volcano
2015/9/15
Turrialba Volcano, located in Central-Southern Costa Rica, has been characterized, since the last period of eruptive activity in 1884-1886, by a weak and discontinuous fumarolic activity in the wester...
Evolution of the volcanic plumbing systemof Alicudi (Aeolian Islands - Italy): evidence from fluid and melt inclusionsin quartz xenoliths
Aeolian Islands fluid inclusions crustal xenoliths homogenisation temperature magma plumbing system
2015/9/15
Quartz-rich xenoliths in lavas (basalts to andesites; 90-30 ka) from Alicudi contain abundant melt and fluid inclusions. Two generations of CO2-rich fluid inclusions are present in quartz-rich xenolit...
Estimates of fluid pressure and tectonic stress in hydrothermal/volcanic areas:a methodological approach
hydrothermal fluids faults cracks fluid pressure volcanic/hydrothermal areas seismicity
2015/9/10
An analytical approach to estimate the relative contribution of the fluid pressure and tectonic stress in hydrothermal/
volcanic areas is proposed assuming a Coulomb criterion of failure. The analyti...
A model of sulphur solubility for hydrous mafic melts: application to the determination of magmatic fluid compositions of Italian volcanoes
sulphur hydrous basalts volcanic gas
2015/9/10
We present an empirical model of sulphur solubility that allows us to calculate f S2 if P, T, fO2 and the melt composition,
including H2O and S, are known. The model is calibrated against three main ...
Fluid transfer and vein thickness distribution in high and low temperature hydrothermal systems at shallow crustal level in southern Tuscany (Italy)
Hydrothermal systems Vein thickness distribution Transmissivity Tuscany
2015/8/17
Geometric analysis of vein systems hosted in upper crustal rocks and developed in high and low temperature hydrothermal systems is presented. The high temperature hydrothermal system consists of tourm...
On the possibility of wave-induced chaos in a sheared,stably stratified fluid layer
wave-induced chaos sheared,stably stratified fluid layer
2009/11/16
Shear flow in a stable stratification provides a waveguide for internal gravity waves. In the inviscid approximation, internal gravity waves are known to be unstable below a threshold in Richardson nu...
We present a numerical study of the generation and evolution of a mixed layer in a stably stratified layer of Boussinesq fluid. We use an external forcing in the equation of motion to model the experi...

2009/11/16
The centre manifold approach is used to derive an approximate equation for nonlinear waves propagating in a sheared, stably stratified fluid layer. The evolution equation matches limiting forms derive...
