Developments offshore Norway
Development of infrastructure has made increasing recovery of petroleum resources possible.•Sharing of processing and transport capacity has allowed successive tie-in of smaller discoveries. •A similar development will take place further north as new major field developments provides tie- in possibilities for smaller discoveries.

From South toward North in 35 years
Deeper waters, harsher environment, stretched technology
Technology steps•Laying of pipelines in deep waters and challenging land approaches•From vertical wells to extended reach horizontal smart wells•Well stream multiphase flow in pipelines over long distances•From wellhead platforms to subsea satellites •From steel jackets, deep water concrete platforms to floating production and extended subsea developments
