A down hoie tool for removing debris from a wellbore comprises a mandrel and a shroud disposed around a portion of the mandrel. The mandrel includes at least one mandrel port in fluid communication with a mandrel bore. The shroud includes a cavity and a shroud port. Debris laden fluid is pulled into the shroud cavity by flowing fluid through the mandrel bore, out the mandrel port, into the shroud cavity, and through the shroud port. The debris-laden fluid is pulled into the shroud cavity due to a pressure differential created by the flow of the fluid through the mandrel port and out of the shroud port. As the debris laden fluid flows into the shroud cavity, the debris is captured within the tool. |
