... Abstract The increasing demand to plug & abandon (P&A) subsea wells has reinforced the need to identify true opportunities to reduce the costs of subsea abandonment. The existing method in typical P&A programs of switching from a light well intervention vessel (LWIV or dedicated...

... looking for the efficiency of the offered activities. In the well interventions’ world, the combination of cheaper and, still good in quality, services will not guarantee the lowest overall cost in a campaign. Aspects, such as, the existence of the built for purpose interventions features, experience...

... Abstract Riserless Light Well Intervention (RLWI) operations have been routinely performed for more than 25 years in the North Sea, with 5 vessels delivering riserless production enhancement operations in several hundred wells, helping the Operators to increase the oil recovery rates from...

The experiences and synergies of RLWI operations have enabled continuous development...

... and sourcing rigs becomes more and more difficult. Thus, recovery factors are much lower—typically 10% to 30% lower—than recovery rates of dry-tree, platform-based wells. Therefore, cost-effective riserless light well interventions (RLWI) are crucial if subsea operators are to realize the full potential of 50...
