Injection testing in geothermal wells

Transient pressure analysis methods were applied to analyze the results of injection tests carried out in a recently completed geothermal well in Los Azufres Geothermal field in Mexico. Potential use of those methods (employing injection, two rate injection and fall of tests) is illustrated in obtaining important well and reservoir parameters at the well completion stage and in predicting future well performance. Also, based on the experience obtained with this well and other similar wells, suggestions are made on the type of analysis which is most applicable.
