Abstract
Disclosed is a downhole well filter () and method of use in a tubing string with a power head () for creating reverse flow. The filter assembly includes an inner pipe () into which fluid flow is directed. The inner pipe is positioned within a cylindrical screen member (). The well fluid flows through the screen member and debris from the fluid is deposited in the annulus () between the inner pipe and screen member. The screen member has a cap () at its upper end to prevent fluid from escaping from the upper end of the screen member. The cap may have a pop off valve () so fluid can escape from the screen member when the screen becomes clogged with debris or pressure builds within the screen member.
