Umbilical

Description

Recently, level of different and complicated well repair is increased. Requirements for tools that used in these operations are constantly growing. A lot of technique is developed already which requires at the same time hydraulic channel for supply of technological fluids, power conductors for power supply for different tools and signal conductors for control of ongoing processes. The company OOO Pskovgeokabel designed umbilicals which contain hydraulic channels and electric conductors of different section. The umbilical has sufficient breaking force and rotational stiffness and can be wound on a reel of geophysical winch, coiltubing machine of stationary winch.
