Abstract
The downhole tractor further comprises a hydraulic power pack coupled to the hydraulic supply line, at least one hydraulic component and at least one further hydraulic component. The hydraulic components are coupled to the hydraulic supply line in parallel and configured for being actuated by the hydraulic supply line. The hydraulic supply line comprises a controllable valve placed at a location in between the at least one hydraulic component and the at least one further hydraulic component such that a first part of the hydraulic supply line is coupled to a second part of the hydraulic supply line via the controllable valve. The downhole tractor provides for much better control and facilitates tuning of the performance of the tractor to the actual needs.
