  • Patent number: 4838354
    Abstract: A clean-out tool system for use with a oil well production tubing extending downward through a casing terminating in a production zone in the well bore, which zone is isolated by a packer and includes flow restricting debris to be cleaned out. A generally vertical, elongated, cylindrical tool body, having a relatively small diameter and a bore therein, is located down through the inner production tubing into the zone located at the end of a tubing string extending downward through the production tubing for communicating fluid pressure to the bore in the body. Four, peripherally spaced, elongated slots extend radially inward into the body with their longitudinal axes aligned with the longitudinal axis of the body and communicate with the bore in the body. An elongated blade is pivotally attached in each slot to the body, movable from a first configuration wherein the blade is positioned vertically within the slot, and a second, expanded configuration positioned radially outward in the zone.

  • Patent number: 4817725
    Abstract: A down-hole oil field cable abrader having an elongated abrading head pivotally connected at one of its ends to a body attachable to a tubing string. An abrading portion extends axially along the abrading head from its pivotal connection and includes a plurality of abrading elements, similar to the cutting elements on a drill bit, spiralling axially about the abrading head ending in a taper to an area distal to its pivotal connection.
