摘要： Work string-mounted cleaning tool and a method of assembling such tools using a quick release for the cleaning element. Oblong pad element has a curved upper surface with slots to receive work surface segments. Opposite edge has a part-circular recess with part-circular peripheral lip around an upper edge of the recess. A retainer fastening component in the recess has a core with socket adapted to receive a driving tool. The retainer is sized to permit it to rotate when mounted within the recess. Roll pins are provided for use in locating the fastener component in predetermined rotational configurations in relation to the recess. Shear pin is provided to inhibit unintended rotation of the fastener component, and to lock the retainer for normal use of the cleaning tool. Shearing of the shear pin permits disassembly of the tool.

摘要： A downhole packer for providing a seal in a well bore to allow integrity testing of well bore with drill ahead capability immediately thereafter has a disengageable packer assembly wherein the packer element may be rendered disengageable by mounting the packer to the string using a tool body (61) provided with a sleeve (62) bearing a packer element (55), wherein the body is initially restrained from movement within the sleeve by engagement of an internal selectively movable retaining element (64). A method of testing a well bore with follow on drilling after disengaging the packer element is described.

摘要： A cleaning tool (1) for use in cleaning ferrous material from a wellbore has a magnetic cleaning functionality by provision of magnets (5) in an Halbach array on a downhole tool component of a workstring. The Halbach array may be an Halbach cylinder positioned on a mandrel wherein the magnetic field is external to the cylinder with substantially zero magnetic field within the tool.
