How to get out of a predicament of an unexpected side-track

A geothermal well doublet producing from a 75°C aquifer, had been operated for over 29 years. The last calliper run performed to control the ID of the 9 5/8” casing indicated there was corrosion and sediments clogging the inner side walls of the injector well, which was hindering production. To regain well integrity, a workover was performed to clean out the 9 5/8” casing in order to reline it.
