Geochemical characteristics of waters from the reservoir of the hydrothermal system of Las Tres Virgenes, Baja California Sur, Mexico [Características geoquímicas de las aquas del reservorio del sistema hidrotermal actual de las tres Vírgenes, Baja California Sur, México] 

Partida E.G.; Hinojosa E.T.; Verma M.P.
The Las Tres Virgenes geothermal field is a liquid dominated system. The separated produced by the wells are sodium-chloride type, which is a characteristics of totally equilibrated geothermal brine. The temperature of ...

A new method of damage determination in geothermal wells from geothermal inflow with application to Los Humeros, Mexico 

Aragón A.A.; Arellano V.M.G.; García A.G.; Barragán R.M.; Izquierdo G.M.; Verma M.P.
Geothermal inflow type curves were obtained for different values of well damage (i.e., inflow performance relationships). The method was evaluated by diagnosing the damage of thirteen producing wells in the Los Humeros, ...

Temperature field simulation with stratification model of magma chamber under los humeros caldera, Puebla, Mexico 

Verma M.P.; Verma S.P.; Sanvicente H.
A simulation of the temperature field underlying Los Humeros caldera is obtained through numerical solution of the energy-conservation equation for a conductive heat flow process. The up-date information on geological, ...

13C, D and 18O isotope geochemistry of fluids in the Los Humeros geothermal system, Puebla, Mexico [Geoquimica isotopica de 13C, D y 18O de fluidos del sistema geotermico Los Humeros, Puebla (Mexico)] 

Portugal E.; Verma M.P.; Barragan R.M.; Manon A.
Isotopic determinations of δ13CCH4, δDCH4 and δ13CCO2 and δ18O and δD in fluids from wells in the Los Humeros geothermal field and natural springs are presented. There is no migrated steam (excess steam) in the feeding ...

Geochemical and isotopic monitoring of rainwater in the Los Azufres and Los Humeros zones, relation to geothermal fluids 

Verma M.P.; Santoyo S.; Aragon A.; Fernandez M.E.; Tovar R.; Casimiro E.; Sandoval F.; Johnson C.; Gerardo-Abaya J.
This work presents the preliminary results of chemical and isotopic monitoring of rainwater in the Los Humeros and Los Azufres geothermal fields and their surroundings during 1995-1998. The rainwater samples were collected ...

Estimates of geothermal reservoir fluid characteristics: Geosys.chem and WATCH 

Torres-Alvarado I.S.; Verma M.P.; Opondo K.; Nieva D.; Haklidir F.T.; Santoyo E.; Barragán R.M.; Arellano V.
A comparative study of the reservoir fluid characteristics calculation of ten production wells of Los Azufres, Los Humeros and Cerro Prieto geothermal fields using two computer codes GeoChem (GeoSys.Chem) and WATCH is ...
Thumbnail

Thermodynamic classification of vapor and liquid dominated reservoir and fluid geochemical parameter calculations 

Verma M.P.
A thermodynamic definition is presented to classify vapor and liquid-dominated geothermal reservoirs. The vapor-dominated reservoir has a specific volume of fluid (i.e. combined vapor and liquid) greater than the critical ...
Thumbnail

Chemical thermodynamics of silica: A critique on its geothermometer 

Verma M.P.
The chemical thermodynamic concepts used in the calculation of solubility data of silica (quartz) are presented taking into account the PVT characteristics of water. The temperature-dependence trends between the thermodynamically ...
Thumbnail

Declining productivity in geothermal wells as a function of the damage effect 

Aguilar A.A.; Montalvo G.I.; Gómez V.A.; Verma M.P.; Morales M.G.B.
The inflow curve may be used to determinate the damage effect and wellbore characterization in geothermal fields. The methodology can be applied for determining damage effect in wells that cannot be retired from continuous ...
Thumbnail

Development of a numerical hydraulic model of the Los Azufres steam pipeline network 

García-Gutiérrez A.; Martínez-Estrella J.I.; Hernández-Ochoa A.F.; Verma M.P.; Mendoza-Covarrubias A.; Ruiz-Lemus A.
The development and documentation of a hydraulic model of the steam pipeline network at the Los Azufres geothermal field is presented, as well as the results obtained using one- and two-phase numerical simulators. Flow ...
