Teledyne DGO offers an advanced, high-reliability subsea wellhead single channel electrical feedthrough system for use in intelligent completions with permanent downhole instrumentation. The pressure-compensated 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.
