Fluid displacement methods and apparatus for hydrocarbons in subsea production tubing
Abstract:
The method for subsea well intervention includes creating a lubricator section within the production tubing of the well. The lubricator section can then be flushed of hydrocarbons facilitating further well intervention from the open water. An intervention device that facilitates flushing production tubing that has equipment, such as electric submersible pumps, is deployed in the wellhead, for example in the valve tree.
