ABSTRACT:
A bailer is configured to remove particulate solids from fluid passing through the bailer. The bailer preferably includes a housing that includes an intake and an outlet to permit the flow if well fluids through the housing. The bailer also includes a magnetic plate that includes at least one aperture that provides a path for the fluid flow. The bailer optionally includes one or more elongate magnetic bars that extend along the longitudinal axis of the bailer housing. The bailer can be used in conjunction with other components in a downhole pumping system, a surface pumping system or a transport system.
