Aberdeen-based Deep Casing Tools, completes first operation of its 'Turbocaser' in the Norwegian North Sea, with a successful 21 hour reaming run. The Turbocaser™ Express is a high-speed drillable reaming system that enables drilling teams to land casings and intermediate liners at target depth first time. Two conventional attempts to run a 7” liner to total depth (TD) had been unsuccessful in the Statoil operated Gullfaks’ satellite well, resulting in the liner hanging up hundreds of metres from TD.
