The Riserless Light Well Intervention Technology provides access to subsea wells.
Reducing the cost of maintenance is the principal driving force behind the development of the LWI technology. With increased access for only at one-third of the cost of a typical intervention, oil companies can better monitor and gather more information from the reservoirs worldwide.
Well maintenance can be performed using Dynamically Positioned (DP) vessels instead of large anchored drilling rigs at shorter time and lower cost. The RLWI technology includes a patented lubricator system with a recirculation of hydrocarbons into the well. The system is deployed through a moonpool from a dynamically positioned vessel, installed on the subsea Christmas tree without the use of anchors or risers.
Riserless Light Well Intervention technology increases the potential to recover one billion barrels of oil off the coast of Norway. According to the statistics from the Norwegian Petroleum Directorate (NPD) conventional subsea wells extract eight percent less oil than regular sea wells. The intention of the RLWI technology is to equalize this gap, representing a U.S. $30 billion increase for Norway's oil recovery over a ten-year period. Increased oil recovery and revenue is not limited to Norway but can be experienced worldwide.
