The Åsgard subsea development incorporates three separate fields 120 miles offshore at 984-ft water depth in the Norwegian Sea: Smørbukk, Smørbukk Sør and Midgard, Fig. 1. The prospect development is at an advanced stage with limited availability of subsea template slots for new well development. On Smørbukk Sør Field, there are four templates: three for production and one for injection. The injection template had only one available slot. Since Statoil planned to inject gas into two formations, it was necessary to drill a multilateral well using the single slot. This well would require a Technology Advancement for Multilaterals (TAML) Level 4 multilateral (ML) junction system to prevent sand incursion, which was a problem with both formations, and it would also have to be capable of being switched to production after 10 years of gas injection.
