Abstract: A well cleaning apparatus and method of treating a well includes a generally tubular implement which has a first section with adjustable, radially extending cables, and a second section with cable loops extending outward, a bottom cone-shaped plug and a top plug. The first section cables can be anchored by rotating or sliding a crimping tube therein, or by molten material poured therein. The second section cable length can be adjusted by a sliding base bracket. The first section chops up scale, sludge and tar while the second section cables sweep them away. The method includes these steps, as well as steaming the casing at high pressure and low water volume to aid cleaning, and stimulate formation flow without creating sand bailing problems. The apparatus can be attached to the bottom of a well pump, with several first sections spaced along the length of the work string of the pump to enable cleaning of the entire well casing by a limited upward and downward movement of the entire assembly.
