Table 3 Sensitivity of the area against changes in porosity

From: Production forecast and estimation of the recovery factor of the Los Humeros geothermal field, Mexico

Well \(r\left({\phi }_{100\mathrm{\%}}\right)\) (%) \(r\left({\phi }_{80\mathrm{\%}}\right)\) (%) \(r\left({\phi }_{50\mathrm{\%}}\right)\) (%) \(r\left({\phi }_{20\mathrm{\%}}\right)\) (%)
H7 100 + 3 + 8 + 13
H12 100 + 2 + 6 + 10
H9 100 + 2 + 5 + 9
  1. From the lack of a proper porosity–depth model for Los Humeros, this comparison took 3 different values of \(\phi\). \(\mathrm{r}\left({\phi }_{100\mathrm{\%}}\right)\) represents the porosity average for this well considering the value at lab conditions reported by Weydt et al. (2020). The entries \(\mathrm{r}\left({\phi }_{80\mathrm{\%}}\right), \left({\phi }_{50\mathrm{\%}}\right), \left({\phi }_{20\mathrm{\%}}\right)\) show the sensitivity on the radius calculation when the porosity decreases by 80, 50 and 20%, respectively. It can be seen that the radius is sensitive to these changes and the highest level of variation is when only 20% of the original value is considered
