PRODUCT DATASHEET TELEDYNE MARINE Single Pin Vertical EFS: Permanent Downhole Gauge For Downhole Completions Teledyne DGO offers an advanced, high-reliability subsea wellhead single channel electrical feedthrough system for use in intelligent completions with permanent downhole instrumentation. The pressurecompensated connection system is designed for long term reliability in demanding subsea and downhole environments. The system operates in extreme HPHT exposure as well as sour well (H2S) conditions, aggressive production and packer fluids. Dual barrier philosophy throughout: • Primary metal seals • We use a minimum of 2 seals for each pressure barrier • Always a minimum of 2 insulators between conductor and earth Qualified I-ET-3000.00-1516-823-PEK-003 PRIMARY FEATURES AND BENEFITS • Glass-to-metal sealed pressure barriers Interchangeable with hydraulic couplers Pressure-compensated system Rig-testable interface seals Standard Ø1/4” (6.35 mm) downhole gauge control line interface Underwater, wet-mateable connectionS Modular design to suit varying installation envelopes Simple, quick, secure, reliable downhole gauge conn
