Claim 10:
11. A desander assembly retrievably positionable in a tubing string, a portion of the tubing string having at least one aperture extending therethrough, the desander assembly comprising:
a fishing neck;
a bypass tool having an internal bore and at least one aperture, the bypass member connected to the lower end of the fishing neck;
a stop assembly connected to the bypass tool, the stop assembly configured to retrievably mate with a portion of the tubing string; and
an inner tubular member having an upper end, a lower end, and a sidewall defining a bore extending between the upper end and the lower end, the upper end of the inner tubular member connected to the stop assembly with the inner tubular member positionable in the portion of the tubing string to form an annulus and so the bore of the inner tubular member is in fluid communication with the bypass tool, the inner tubular member having at least one spiral protrusion extending outwardly from the sidewall to cooperate with an interior side of the portion of the tubing string to form a spiral channel,
wherein the bore of the inner tubular member receives reservoir fluid that passes into the annulus formed between the inner tubular member and the tubing string via the apertures of the tubing string, the reservoir fluid guided downwardly into the spiral channel so the spiral channel induces a cyclonic flow, which causes heavier particles to be forced outwardly and to fall to the lower end of the funnel section, the separated fluid flows into the bore of the inner tubular member via the lower end of the inner tubular member so the fluid continues to travel up through the bore of the inner tubular member and exit from the bypass tool.
