AI Technical Summary

⚠Technical Problem

Existing wellhead penetrators fail to maintain a pressure-tight seal, leading to potential cable damage and corrosion, especially when used with electric submersible pumps, due to exposure to hydrocarbon fluids and high operating pressures.

⚗Method used

A cable penetrator assembly with a mandrel seal assembly and seal spider compression sleeve, featuring metal-on-metal connections, contact bands, and a seal spider, designed to withstand high pressures and prevent deformation, ensuring a reliable seal for power cables.

🎯Benefits of technology

The solution provides a durable seal that withstands up to 5,000 psi, reducing cable failure and corrosion, thereby enhancing the reliability and performance of wellhead penetrators in hydrocarbon extraction systems.

Abstract

System and apparatus for a penetrator in a hanger system to prevent seal failures. A cable penetrator assembly (110) including at least one pin (212), at least one socket (208) disposed within the cable penetrator assembly (110) and configured to couple to the at least one pin (212), a plurality of contact bands (210) disposed in each of the at least one socket (208), a mandrel assembly (130). The cable penetrator assembly (110) may also include an end seal assembly (600A, 600B). The end seal assembly (600A, 600B) includes a top seal (610) and a seal compression plate (630). The top seal (610) includes one or more seal feedthrough apertures (612). The seal compression plate (630) includes one or more plate feedthrough apertures (632).
