Abstract
Matrix acid treatments have been employed in two low to moderate temperature hydrothermal wells with successful results. These two wells showed flow rate increases of 40% and 50%. The increased flow reduced the payback periods for the heating systems to nearly one half of what they were before acidization. It is recommended that well designs in certain areas consider accommodating such acid stimulation techniques, if testing suggest they are warranted as a well completion tool.
