New enclosed well intervention solutions reducing operational complexity and footprint.Capline is a game-changing way to do wireline services. It offers more efficient interventions and introduces new tools for enhanced oil production. The innovation consists of a winch enclosed inside a pressure vessel and installed in direct extension of the well, drastically reducing the complexity and footprint of the operation. The miniaturization is made possible by replacing the steel wire with a robust synthetic fiber rope.Capline is the only way to do well intervention without any dynamic seals, drastically increasing the safety and simplicity of the operations.
