We estimate c$750M of cost savings for a tieback, and c$500M of cost savings for a fully subsea development, as compared against a traditional project with a traditional production facility. Please download the model to see the different cost drivers, line-by-line.
This data-file quantifies the costs and CO2 emissionsassociated with different oilfield development concepts’ construction materials.
We have tabulated c25 projects, breaking down the total tonnage of steel and concrete used in their topsides, jackets, hulls, wells, SURF and pipelines. Included are the world’s largest FPSOs, platforms and floating structures; as well as new resources in shale, deepwater-GoM, Guyana, pre-salt Brazil and offshore Norway.
Infill wells, tiebacks and FPSOs make the most efficient use of construction materials per barrel of production. Fixed leg platforms are higher, then gravity based structures, then FLNG, and finally offshore wind (by a factor of 30x).
