Abstract
The liner pipes of well H-16 from Los Humeros geothermal field were strongly corroded and incrusted by silica and iron sulphides. The corrosion process seems to be happened to an average rate of 0.752 mm/year and HCI from deep zones of the geothermal reservoir seems to be the cause. The scaling of the liner pipe was induced by mixing of the deep fluids and another fluids produced from a shallower zone (around 1400-1450 m depth). Future wells located at the same area of the field (the Central Collapse), should to avoid the mixing of fluids from both zones in order to prevent the scaling and to reduce the corrosion rates.
