Acidizing of geothermal wells

Candidates should be selected on the basis of the same principles as discussed earlier. In geothermal wells, the strongest indication of acid-removable formation damage is a sharp drop in the production rate. In a new well, poor production is the only indication. Well-testing techniques 

Nearly all geothermal wells that are acidizing candidates have been damaged by the following  

Erosion of production lines may occur if drill cuttings are produced back during blowdown of a well after stimulation. Care must be taken in this regard. A temporary flow line may be required until solids produaion has stopped.
