1. A desander assembly in combination with a tubing string, the desander assembly comprising:
an outer tubular member having an upper end, a lower end, and a sidewall with an inner surface defining a bore extending between the upper end and the lower end, the outer tubular member having at least one aperture extending therethrough in fluid communication with the bore; and
an inner tubular member having an upper end, a lower end, and a sidewall defining a bore extending between the upper end of the inner tubular member and the lower end of the inner tubular member, the inner tubular member connected to the tubing string and the outer tubular member with the inner tubular member positioned in the outer tubular member to form an annulus and so the bore of the inner tubular member is in fluid communication with tubing string, the lower end of the inner tubular member being spaced a distance below the at least one aperture of the outer tubular member,
wherein the bore of the inner tubular member receives reservoir fluid that passes into the annulus formed between the inner tubular member and the outer tubular member via the at least one aperture of the outer tubular member, and
wherein the at least one aperture of the outer tubular member is angled so the reservoir fluid is directed tangentially into the outer tubular member along the inner surface of the outer tubular member to induce a cyclonic flow around at least a portion of the inner tubular member, which causes heavier particles to be forced outwardly and to fall to the lower end of the outer tubular member, 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 the tubing string.
