Abstract:
A downhole apparatus comprising a body configured to be coupled to a production tubular and an upper opening and a lower opening. First and second flow paths are provided between the upper opening and the lower opening in the body, and a flow diverter is arranged to direct downward flow through the body towards the second flow path and away from the first flow path. A filter device in the second flow path filters or collects solid particles in the second flow path from passing out of the lower opening of the apparatus. The apparatus has particular application to artificial lift hydrocarbon production systems, and may be installed above a downhole pump in a production tubing to prevent solids from settling on the pump during pump shutdown. Embodiments for use with ESPs and PCPs are described.

Claim (Index 1):
A downhole production apparatus comprising:\n a body configured to be coupled to a production tubular and installed upward of a downhole pump, wherein the body comprises an upper opening and a lower opening; an inner tubular in the body, wherein the inner tubular comprises a wall and one or more vents; an annular space between the wall of the inner tubular and a wall of the body, a bottom of the annular space arranged to collect downward moving solid particles when the downhole pump is shut down; and a flow diverter arranged to direct downward moving solid particles away from an inside of the inner tubular and toward the annular space, wherein the one or more vents of the wall of the inner tubular is physically arranged such that fluid flowing inside of the inner tubular in an upward direction causes upward fluid flow in the annular space via the one or more vents, which carries collected solid particles away from the annular space.
