Abstract
An apparatus for removing sand from a well fluid includes a pressure vessel having an inlet and an outlet. The well fluid flows into the pressure vessel through the inlet and flows out of the pressure vessel through the outlet. A screen is positioned at least partially within the pressure vessel and configured to remove the sand from the well fluid. At least a portion of the sand that is removed from the well fluid at least partially obstructs one or more openings in the screen. A cleaning assembly is positioned at least partially between the pressure vessel and the screen and configured to remove the sand that is obstructing the one or more openings in the screen during a screen-cleaning operation.
