Abstract
The present invention provides wellbore cleaning tool and method featuring a wiper assembly which allows fluid to bypass the tool in one direction while diverting the well fluid through a filter screen in another direction. This may be achieved by either circulation of the fluid in the wellbore or by moving the tool relative to the fluid in the wellbore. The wiper assembly includes multiple groups or series of wiper elements wherein one petal shaped element aligns with a slot to form a seal when the tool body is retrieved from the well.
