Fig. 5From: Production forecast and estimation of the recovery factor of the Los Humeros geothermal field, MexicoValidation of the model given by Eq. (6). The observed value for the extraction is represented as a dot. Forecast using our model with 80% of the data for training is shown as a range whisker. The model is considered to be appropriate when the observed value is inside the range. Wells enclosed in parentheses operated for 22 years and they are not considered for validation as they do not have enough dataBack to article page
