A device and method for removal of debris from well bores coincident with introduction and placement of a bridge plug. The device comprises a hollow cylindrical body open at both ends. The lower end of the device is adapted to form a gauge ring, integral with the body of the device for cleaning or scraping of the well casing. The body of the device is penetrated by a plurality of openings of sufficient size to allow the passage of fluid while confining debris within the body of the device. The upper end of the device is adapted to be frangibly connected to the bottom of the bridge plug to be placed in the well casing. The method includes preparation of a well for production, wherein debris removal and bridge plug placement may be safely and economically performed in a single operation.
