Casing Jack

The Casing Jack is designed as a mobile hydraulic lifting device that can be used both for standard applications and in unusual situations on wells. All components of the casing jack and the control unit are designed in explosion protection class for (Zone 1). This also enables work in gas-critical situations without any problems.

Use cases

For gas storage, the focus is on pretensioning during completion work. Using the casing jack reduces the size of workover rigs and thus completion costs because the system does not need to apply the pretensioning force.

Brine pipe tours are in use for months – or even years. Deposition and crystallisation can cause the pipes or the hanger to wedge when they come ashore. The casing jack directs the tensile force vertically into the system, thereby preventing “skewing” because it is mounted directly on the adjacent flange. The elastic behaviour of workover systems or mobile cranes under high loads, which increases safety risks during spontaneous unloading (spring effect), can be effectively mitigated.

Mobilisation and handling

The compact design of the casing jack, hydraulic unit, and combined working platform and transport frame ensures quick mobilisation. A forklift truck or mobile crane is sufficient for loading work. The mobile control and hydraulic unit can be set up at a sufficient distance from the components subject to tensile or compressive forces, thereby ensuring safe working conditions.
