    Abstract: Some examples of the present disclosure relate to a method for washing an annulus that at least partially surrounds a casing in a well. The method comprises locating a tool inside a wellbore casing, and flowing a washing fluid from an injection aperture on the tool and into the annulus via a first casing aperture in the casing. An inflow region of the casing is created having a reduced pressure relative to the annulus, and the method involves flowing the washing fluid from the annulus and into the inflow region of the casing through a second casing aperture in the casing.

    Abstract: A method of washing pipes comprising the steps of intermittently or continuously driving carbon dioxide gas into a pipe, wherein the foaming action of the carbon dioxide gas dissolved in the water in the pipe is used to wash the interior of the pipe. The method does not require a large-scale facility or operating process, making it possible to wash the inner wall surface of the pipe reliably and very sanitarily in a short time and to check the pipe for water leakage. A method of washing well pipes comprising the step of intermittently or continuously driving compressed air into a well pipe and, simultaneously therewith, spouting high pressure water to wash the interior of the well pipe. When this method is used, the synergistic effect of compressed air and high pressure water reduces the operating time and process, thus making it possible to wash the interior of the well pipe easily and efficiently in a short time.
