  • Arrangement, device and method for resolving hydrate plugs
    Patent number: 9157290
    Abstract: An arrangement for resolving a hydrate plug (1) in a pipeline (2), such as tubing, drill pipe, casing etc., is described, said arrangement comprising a heating device (4) run on wire line. The heating device (4) is elongated and spear shaped and is mounted on a stroking device (3), the stroking device (3) being adapted to provide a pushing force of sufficient strength to force the heating device into the hydrate plug (1). The heating device then has a large surface towards the hydrate plug. When heat is applied to the heating device, the hydrate plug will melt. A hydrate inhibitor may be added to the liquid near the hydrate plug.

  • Tool for centering a casing or liner in a borehole and method of use
    Patent number: 9097069
    Abstract: There is disclosed a tool for centering a casing or liner In a borehole. The tool Includes a tubular section Inserted In the casing/liner. A number of pressure cylinders (4) are mounted in the tubular section along the circumference. The pressure cylinders may be expanded by pressure from the Inside of the tubular section. In use, the casing/liner with the tubular section is run into the borehole with the pressure cylinders retracted. Thereafter, the pressure Inside the casing/liner Is Increased pressing the pressure cylinders out and centering the casing/liner.
