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 22):
A downhole production apparatus comprising:\n a body configured to be coupled to a production tubing and installed upward of a downhole pump, wherein the body comprises an upper opening, a lower opening, and a throughbore; an inner tubular in the body, the inner tubular dividing the throughbore into a first flow path and a second flow path, wherein the second flow path is arranged to collect downward moving solid particles when the pump is shutdown; one or more vents to provide for fluid communication between the first flow path and the second flow path; a flow diverter arranged to direct downward moving solid particles away from the first flow path and toward the second flow path, wherein the one or more vents is physically arranged such that production fluid flowing in the first flow path in an upward direction causes fluid flow in a lower half of the second flow path, which carries collected solid particles away from the second flow path.
