  • System for continuous electrical well cable feed-through for a wellhead and method of installation
    Patent number: 10033174
    Abstract: An epoxy sealant confined around a transition seal body system for a down hole electric cable transition from a protected cable to separate conductors of a three-phase electrical service provides a vapor and pressure seal, preventing premature failure from temperature and pressure changes in the wellbore. The use of epoxy to completely surround the transition seal body within the penetrator mandrel permits field installation of continuous electrical conductors from a wellbore through a pressure sealing wellhead to the surface.

  • SYSTEM FOR CONTINUOUS ELECTRICAL WELL CABLE FEED-THROUGH FOR A WELLHEAD AND METHOD OF INSTALLATION
    Publication number: 20140110164
    Abstract: An epoxy sealant combined with a transition seal body system for a down hole electric cable transition from a protected cable to separate conductors of three-phase electrical service provides an effective vapor and pressure seal preventing premature failure from temperature and pressure changes in the well bore. The use of epoxy completely surrounding the transition seal body within the penetrator mandrel permits safe and effective field installation of continuous electrical conductors from a wellbore through a pressure sealing wellhead to the surface that is easier to install and more protective than previous mechanical connections.

  • Methods, systems, and products for marking concealed objects
    Patent number: 8118192
    Abstract: Methods, systems, apparatuses, and products are disclosed for locating concealed objects by discharging the contents of an aerosol container. A housing encloses an inner volume, and a hollow conduit extends along the housing. An elongate rod slides within the conduit. An actuator of the aerosol container is engaged between a discharge position and a non-discharge position by movement of the elongate rod.
