“…Additionally were developed inflow relationships assuming the geothermal fluid is composed by: 1) Pure water [34]; 2) A binary mixture H 2 O-CO 2 [35,36]; 3) A ternary mixture H 2 O-CO 2 -NaCl with salinity less than 5000 ppm of NaCl [37]; 4) [38] Assumes a ternary mixture H 2 O-CO 2 -NaCl with salinities between 5000 and 30,000 ppm of NaCl; and 5) A ternary mixture H 2 O-CO 2 -NaCl with salinities greater than 30,000 ppm of NaCl [39]. The incorporation of the damage effect in the inflow relationships was proposed for petroleum systems [25] and for geothermal systems [16,[39][40][41].…”

A review of the art state was developed about the inflow relationships and their application for reservoir characterization. The theoretical development of the methodology for determining the damage effect using type-curves of the inflow relationships was shown. We show the process followed for achieve the geothermal type-curve affected with damage for reservoirs with mean salinities of 30000 ppm and temperatures up to 350℃. This type-curve was applied using measurement production data in a Mexican geothermal field. According with the obtained results is shown that the methodology for determining the damage effect using production measurements is a sure alternative for the damage effect calculation. It was used an alternative methodology in order to validate the damage presence and the obtained results were consistent. Last thing shows that both methodologies can be combined as a confident manner

“…In a later study, Moya (1994) incorporated the effect of non-condensable gases developing a solubility model for the binary mixture H 2 O-CO 2 (Moya and Iglesias, 1992;Iglesias and Moya, 1992). The applicability of these typecurves for the estimation of the productivity of geothermal wells was discussed by Moya et al (1998) and Iglesias and Moya (1998). This methodology to estimate the productivity of geothermal wells was automated (Moya and Uribe, 2000) and later complemented with the estimation of the permeability of the rock formation adjacent to the well (Moya et al, 2001;2003).…”

Highly saline geothermal reservoirs show problems of salt precipitation on the rock formation reducing its permeability and the well’s productivity. In this study, theoretical curves of mass productivity of geothermal wells (inflow type curves) were obtained considering ternary mixtures of H2O-CO2-NaCl of up to 25% salinity in weight and under different initial conditions of gas saturation of the fluid. The sensitivity analysis to the initial concentration of salts and initial gas saturation was carried out using the simulator TOUGH2. The developed type curves are focused to reservoirs with criti-cal characteristics such as, low permeability, ranges of high salt precipitation and high gas saturation. The obtained curves show three clearly defined zones as a function of the degree of exploitation of the well: no salt precipitation zones; transition zones; and salt precipitation zones. It was found that salt precipitation in the reservoir occurs in greater intensity at higher initial concentrations of dissolved salts and higher gas saturation. In some cases, scale obstructs the pores of the rock formation drastically reducing its permeability. It is proposed that type curves could be used as complementary tools for the analysis of wells and for the selection of pertinent strategies for the exploitation of geothermal fields.
