Abstract
In this work a review of Inflow Performance Relationships (IPR), their development in petroleum reservoir engineering and the innovations made to incorporate the damage effects are presented. In analogous manner the Inflow Performance Relationships for geothermal reservoir are shown. The Inflow Performance Relationship and their corresponding type-curve with damage effect for geothermal reservoirs is proposed. In this paper for the first time, a methodology to determine the value of damage in a well, from its production test data, is established. The applicability of this innovative method using data from three production tests carried out in well M-110 at the Cerro Prieto geothermal field is demonstrated. Such tests were performed in the well at different stages of its productive life; therefore it is possible to identify the variation of the damage value.
