Three distinct hydrothermal zones can be identified in the well A-29, located at the northeastern border of the Los Azufres, Mexico, geothermal field. They are the zeolite, epidote and amphibole-gamet zones. High temperatures (over 300{degrees}C) were measured, but the well did not produce mass flow. This can be explained by a self-sealing process as a result of three trends recognized in the evolution of geothermal fluids: boiling, boiling and gas losses, and dilution. A certain cooling of at least 25{degrees}C seems to be happening in the well, especially in the epidote zone and in the upper portions of the amphibole-gamet zone.
