Practical Uses of Geothermal Type-curves with Damage Effect in a Mexican Geothermal Field

Practical Uses of Geothermal Type-curves with Damage Effect in a Mexican Geothermal Field

The productive characteristics of the wells diminish with the exploitation time and this fact is related
with the damage effect. In this work the characteristics that originate the damage effect are described.
At present, have been demonstrated that the inflow relationships and their application to reservoir
characterization is one of the practical tools in reservoir engineering. The theoretical development of
the methodology for determining the damage effect using type-curves of the inflow relationships was
shown. Similarly, the process to obtain the type-curve for reservoirs with mean salinities of 30000 ppm
and temperatures up to 350°C is shown. Were used measured production data of six of the wells of
Los Azufres Mexican geothermal field and applied to type-curve with damage effect. It was 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. From the obtained results it
can be assumed that both methodologies can be combined as a confident manner. The increase of
damage effect during the well exploitation stage, is related to deterioration of its productive
characteristics and this fact helps to establish technical criteria in the taking decisions about the
operations that must be apply in it (such as cleaning, repairs, fracturing, stimulations, etc., among
others).Through obtained results, it is demonstrated that the proposed methodology can be useful for
taking decisions about the appropriate managements to apply in the well in order to improve its
productivity.
