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.

Fluid displacement methods and apparatus for hydrocarbons in subsea production tubing

An intelligent completion system includes production tubing configured for production from multiple zones in a wellbore. At least one flow control valve is disposed on the production tubing for each of the multiple zones, this flow control valve capable to regulate the flow of a wellbore fluid into the production tubing. A chemical injection mandrel is disposed on the production tubing adjacent the at least one flow control valve in the each of the multiple zones, this mandrel being connected to at least one chemical injection line for injecting one or more chemicals into the wellbore. A control mechanism is connected to the at least one flow control valve and the chemical injection mandrel such that the injection mandrel and the at least one flow control valve are operated in a coordinated manner.
