Abstract
A method for cleaning a casing of an oil well is disclosed. Operational parameters for a cleaning tool may be defined based, at least in part, on results of a survey of the well. The cleaning tool may include a discharge head to generate electrical discharges between a pair of electrodes, the electrical discharges causing shock waves to remove deposits from the casing. The cleaning tool may be lowered into the casing. The cleaning tool may generate shock waves in accordance with the defined operational parameters to clean a predetermined target portion of the casing. The cleaning tool may be withdrawn from the casing.
