Publication number: 20190376359Abstract: A hydrophobic dielectric sealing material is provided that is especially suitable for use in extreme environments such as for enabling downhole electrical feedthrough integrated logging tools reliable operation, especially, in a water or water-mud filled wellbore as first scenario or in moisture-rich oil-mud filled wellbores. In some embodiments, a hydrophobic dielectric sealing material may include: H3BO3 10-60 mol %; Bi2O3 10-50 mol %; MO 10-50 mol %; SiO2 0-15 mol %; and optionally one or more rare earth oxides 0-5 mol %. A method for making hydrophobic sealing material includes selecting water insoluble raw materials, form tetragonal phase dominated phase, and enlarge band-gap with wide-band-gap material. The morphology of the sealing material is preferably a tetrahedral phase dominated covalent bond network for obtaining high electrical insulation resistance, dielectric strength and hydrophobicity, and high mechanical strength in against downhole 30,000 PSI/300° C. water-based hostile environments.Type: ApplicationFiled: June 10, 2018Publication date: December 12, 2019Applicant: PA&E, Hermetic Solutions Group, LLCInventors: Hua Xia, Nelson Settles, Gaery Rutherford

Patent number: 10483745Abstract: A method for making a downhole electrical feedthrough package where the feedthrough package may include a metal shell forming a shell conduit. A metal web may be coupled to the metal shell, and the metal web may form a web conduit. A conducting pin may extend through the shell conduit and web conduit. A dielectric seal may electrically isolate the conducting pin from the metal web. The dielectric seal may be formed by a bismuth glass based dielectric sealing material system having at least two of the four components selected from Bi2O3, B2O3, MO, and optionally REO forming a bismuth glass system. MO may be selected from ZnO, BaO, TiO2, and Fe2O3, and their glass making pre-cursors. REO may be selected from CeO2, Y2O3, Sc2O3, Nd2O3, Pr2O3, and lanthanum series oxides. One or more isolators may be disposed within the shell conduit proximate to the dielectric seal and surrounding a portion of the conducting pin.Type: GrantFiled: April 3, 2019Date of Patent: November 19, 2019Assignee: PA&E, Hermetic Solutions Group, LLCInventors: Hua Xia, Nelson Settles, Tucker Havekost, Don Larson
