A Review of Geothermal Type-Curves with Damage Effect: A Case of Practical Apply to a Mexican Geothermal Field

Abstract

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

Evaluation of the productivity of geothermal wells by analyzing production measurements and the damage effect

“…The wells located in the North zone (5 and 13) produce reservoir fluids characterized by a water‐steam mixture (with average values of total discharge enthalpy of 2,300 kJ/kg and reservoir temperature of ~300 °C), whereas for the South zone, most of the wells produce fluids with a high steam fraction with average values of total discharge enthalpy of 2,300 kJ/kg and reservoir temperature of ~280 °C. Flowing measurements for these four geothermal wells were collected from the experimental works reported by López‐Blanco et al .…”
