“…The Los Humeros reservoir has been characterized by very high temperatures (>300°C) at depths below 1500 m [2]. Temperatures of >400°C have been estimated for some deep wells [3] while measured temperatures up to 398°C have also been reported. In this field, chemical gas and liquid geothermometers provide different temperature estimations.…”

The thermal evolution of Los Humeros geothermal fluids was estimated by using liquid and gas chemical geothermometers and results indicate two separated fluid entries to the wells: a (~250°C) liquid produced from a shallower reservoir and a (>300°C) steam produced by a deeper stratum. Both entries were identified by Na/K and SiO 2 geothermometers for the liquid and H 2 /Ar for the steam. CO 2 /Ar geothermometer seems to provide temperatures of mixed fluids entering the wells. Based on thermal evolution of fluids, multiple fluid entries in wells were characterized while reservoir exploitation-related processes like cooler water entries and condensation phenomena, were also identified.

“…2 and 3). From this, we deduce that the geothermal reservoir of Los Humeros is in the steam-domain, as has been proposed in the literature (White et al, 1971;Truesdell & White, 1973;Silvester & Pitzer, 1976;Ellis & Mahon, 1977;Arnorsson et al col., 1982;D'Amore et al, 1990;Verma et al, 1998;Prol-Ledesma, 1998;Gonzalez Partida et al, 2001;Arellano et al, 2003;Tello, (Truesdell, 1991;Gonzalez Partida et al, 2001;Tello, 2005). …”

“…Such a model also is the first stage of mathematical modelling of the field. Several conceptual models of high energy geothermal fields have been published (see for instance (Westercamp and Traineau 1987;Akasako, Matsuda et al 2002;Arellano, Garcia et al 2003;Batini, Brogi et al 2003;Tamanyu and Wood 2003;Bertini, Casini et al 2006;Dilsiz 2006) for a context of andesitic type volcanism (or for shallow granitic intrusions), or (Bodvarsson, Benson et al 1984;Bodvarsson, Pruess et al 1984a;Bodvarsson, Pruess et al 1984b;Gandino, Guidi et al 1985;Ingebritsen and Scholl 1993;Violette, Ledoux et al 1997;Hulen and Anderson 1998) for basaltic type volcanism. Most of these conceptual models present, with varying degrees of precision and exclusively in 2D (cross section), the geological and geophysical structure of the subsurface.…”

“…The modes of heat transfer to the surface remain generally imprecise. The respective roles of different types of "fluid" (water, gas, steam) (Akasako, Matsuda et al 2002;Arellano, Garcia et al 2003;Tamanyu and Wood 2003) or of water at different temperatures, and the different means of thermal energy transfer (conduction, convection, advection) are in some cases distinguished (Tamanyu and Wood 2003). The effects of thermal blanketing and interaction with subsurface hydrosystems (cold aquifers) are mentioned for certain sites (Gandino, Guidi et al 1985;Westercamp and Traineau 1987;Clemente and Villadolid-Abrigo 1993;Ingebritsen and Scholl 1993;Violette, Ledoux et al 1997;Akasako, Matsuda et al 2002;Tamanyu and Wood 2003), but always with a low degree of precision concerning the definition of the concerned aquifer structure and flow directions (the latter mostly as schematic arrows, and generally without individualizing the concerned aquifers), and, in most cases, without a precise quantification of the water fluxes between the geothermal aquifer and the surface (cold aquifers and/or surface waters).…”

Hydrogeological model of a high-energy geothermal field (Bouillante area, Guadeloupe, French West Indies)

The Bouillante geothermal field presently provides about 8% of the annual electricity needs of the French West Indies island of Guadeloupe. It has been the subject of a large number of studies covering various disciplines. These results enable the proposal of a hydrogeological conceptual model of the field. The reservoir consists of two perpendicular sets of fractures and faults, related to major regional tectonic structures. The capacitive and transmissive functions of the field are assured by these deep faults and fractures, which have been clogged near surface by self sealing and clay fill phenomena. The heat exchanges of the reservoir with the outside are thus reduced, through thermal and moreover hydraulic blanketing, to conductive transfers. Convection cells are active within the reservoir, ensuring its thermal and geochemical homogeneity. Heat exchange with the magmatic chamber is only conductive. The Na-Cl geothermal fluid in the reservoir is composed of about 60% sea water and 40% fresh water of meteoric origin and has reached a chemical equilibrium with a mineralogical assemblage at 250-260°C. This equilibrium state, the absence of tritium in solution, the low ratio between water in and out fluxes and the large reservoir volume (estimated at more than 30 millions m 3 using tracer tests) suggest a relatively long (>> 100 years) residence time of the geothermal fluid in the reservoir. Three main factors, all essential, explain the existence and location of the Bouillante geothermal field: a heat source (cooling hypovolcanic intrusion), a network of permeable fractures at the origin of the geothermal aquifer, and an impermeable surface cover, limiting the loss of energy and ensuring the durability of the field.
