Reducing the cost of such operations is the principal driving force behind the development of the RLWI technology. FMC’s RLWI Technology enables cost effective intervention operations into existing subsea wells resulting in additional production volumes from mature subsea fields at highly competitive costs for the incremental volumes of oil.
The technology includes a patented lubricator system for inserting downhole tool packages into the wellbore under full pressure and without taking hydrocarbons back to the vessel. All equipment to connect to and control the subsea well is deployed from the lower cost dynamically positioned monohull vessel without using a drilling or workover risers and anchors.
Riserless Light Well Intervention (RLWI) operations are normally carried out from a dynamically positioned purpose-built intervention vessel to perform the following operations: logging, gauging, plugging, re-perforating and various downhole mechanical works to reduce flow restrictions.
