Borehole sand catcher

A downhole apparatus for collecting solids fallback in a production tubular, comprising:

• a body;
• a first connection component disposed at a first end of the body;
• a second connection component disposed at a second end of the body;
• and
• a plurality of baskets disposed longitudinally in the body,
• wherein each of the plurality of baskets comprises a basket wall provided with openings to permit fluid flow therethrough.

A method of collecting solids fallback in a downhole fluid, comprising:

• providing a solid collection basket having a longitudinal axis, wherein the solid collection basket allows a fluid to flow along the longitudinal axis in a first direction or separately in a second direction, wherein the second direction comprises a direction which is a reverse of the first direction;
• flowing a fluid including particulate matter through the solid collection basket at an initial rate of fluid flow, wherein the flowing comprises the fluid flowing through the solid collection basket in the first direction;
• directing the fluid at least partially through one or more baskets disposed along the longitudinal axis of the solid collection basket,
• wherein each of the one or more baskets comprises a basket surface comprising one or more openings;
• trapping at least a portion of the particulate matter in at least one of the one or more baskets when the rate of fluid flow slows or becomes suspended, or the flowing reverses such that the flowing comprises the fluid flowing in the second direction;
• and
• cleaning the one or more baskets as the rate of fluid flow is restored to the initial rate of flow or as the flowing returns to comprising the fluid flowing through the solid collection basket in the first direction.

A system for trapping particulate matter disposed in a fluid produced from a wellbore, comprising:

• production tubing disposed in a wellbore, the production tubing configured to flow a fluid produced from the wellbore;
• a solid collection basket apparatus connected to the production tubing, the solid collection basket apparatus comprising:
• a body,
• a first connection component disposed at a first end of the body,
• a second connection component disposed at a second end of the body, and
• a plurality of baskets disposed longitudinally in the body,
• wherein each of the plurality of baskets comprises a basket surface comprising one or more openings;
• a pump or lifting mechanism connected to the solid collection basket apparatus, the lifting device configured to flow the fluid at a rate of flow into the production tubing through the solid collection basket apparatus;
• wherein the solid collection basket apparatus collects particulate matter disposed in the fluid when the rate of flow slows, becomes suspended, or reverses.
