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 26):
A downhole production apparatus comprising:\n an outer tubular configured to be assembled into a production string between an upper production string tubing and a lower production string tubing, thereby connecting the upper production string tubing and a lower production string tubing, the outer tubular located upward of a downhole pump; an inner tubular extending along at least a part of the outer tubular, the inner tubular comprising a wall that separates a first flow region on the inside of the inner tubular from a second flow region in an annular space between the inner tubular and the outer tubular, one or more vents in a lower part of the wall of the inner tubular to provide fluid communication between the first flow region and the second flow region; and a flow diverter arranged to direct downward moving solid particles away from the first flow region and toward the second flow region, wherein the one or more vents are physically arranged such that production fluid flowing in the first flow region in an upward direction causes fluid flow in the second flow region, which progressively carries collected solid particles away from the second flow region.
