The operation is performed through smaller dynamic positioned monohull vessels instead of larger mobile installations like traditional semisubmersible drilling rigs or drillships.
[2] Traditional activities are wireline operations for well logging, perforation, and installing or pulling equipment like plugs and downhole safety valve inserts.
RLWI enables the operators to perform intervention to increase the recovery rate at reduced time and cost.
[3] There is a positive safety aspect by employing RLWI services as no hydrocarbons are transported to the vessel, but flushed back into the well through the lubricator system during normal operations.
However, RLWI is a complex operation requiring special expertise and control in all phases of the preparation and implementation.
