  • Publication number: 20210285305
    Abstract: Cement slurry injected or delivered into a wellbore during cementing operations can be positively placed with a positive placement tool. The tool can be located along to a casing string and have a mandrel with a tubular centralizer sleeve rotatably fit thereabout, the centralizer sleeve having one or more radial guides extending longitudinally thereon. Reciprocal stroking of the casing string causes a helical drive arrangement, acting between the mandrel and the centralizer sleeve, to drive the centralizer sleeve longitudinally along a length of the mandrel while concurrently rotating the centralizer sleeve thereabout. The rotational movement of the centralizer sleeve provides positive impetus to force the injected cement slurry fully about the casing string.

  • Patent number: 9951583
    Abstract: A tool is incorporated into a tubing string and is run into a wellbore until an agitator at a bottom of the tool engages an obstruction in the wellbore. A helical drive arrangement between a mandrel and a sleeve causes the sleeve on the outside of the tool, to which the agitator is attached, to rotate as the mandrel is reciprocated between a downstroke and an upstroke. Rotation of the agitator disrupts the obstruction forming debris therefrom and a slurry of the debris in wellbore fluid. At the same time, reciprocation of the mandrel causes a standing valve and a travelling valve in the tool to be alternately opened and closed for pumping the slurry into the tool and from the tool into the tubing string for storage therein. Periodically the tool is tripped to surface and the stored debris is removed from the tubing string.
