Collaborative Strategy Heightens Efficiency of North Sea Predrilling Campaign

The predrilling campaign for the Johan Sverdrup development was a key contributor to the successful execution of the first phase of the megaproject. After a summary of the results of the campaign, the focus of the complete paper is to identify some of the key factors behind the success of the campaign and outline lessons learned relevant to future drilling campaigns. Since the completion of the predrilling campaign, the project has successfully tied back, completed, and begun production of eight predrilled oil producers and injection in 12 subsea injectors.
