Patent attributes
A sand fallback tool having an outer tubular body with proximal end, a distal end, a chamber therebetween surrounding an axis extending from the proximal end through the distal end, a tubular flow divider supported within the chamber to divide at least a portion of the chamber of the outer tubular body into a central passage along the axis and an annular passage radially intermediate an exterior of the tubular flow divider and an interior of the outer tubular body, and an unobstructed axial settling path from the proximal connector into the central passage. One embodiment further includes a tubular extension coupled to the proximal connector and extending along the axis to terminate at a distal end of the tubular extension received within a proximal end of the tubular flow divider to provide an “S”-shaped flow pathway intermediate the annular passage and the proximal connector of the outer tubular body.
