  • Equipment for remote launching of cementing plugs
    Patent number: 8622131
    Abstract: An apparatus for remotely launching cementing plugs is configured such that the length of a dart is not necessarily the same as the corresponding plug to be launched. A hydraulic-liquid reservoir and a piston are incorporated into a plug-launching system. The size of the reservoir may be adjusted such that the axial displacement of the piston after the dart lands is sufficient to cause the expulsion of a plug from the apparatus.
