SFI SWIPA

The SFI-initiative SWIPA aims to obtain a scientific understanding of permanent well barriers and allocate for improved well barrier design methodologies. This will benefit long term well integrity, addressing costs, materials, barrier lengths and operations. A key issue will be to utilise the results for reviewing standards and regulations for P&A of petroleum wells.

The cost reductions target for P&A operations in particular is set to 50 % compared to today`s technology (2020) including impact from revised standards and regulations, new operations and well barrier materials.

Well barrier know-how is a key for successful performance of several energy industries and the results will be applied for reconversion of petroleum wells for CO2 disposal, and well integrity of geothermal wells and disposal of nuclear waste.
