In 2015, Fishbones Drilling was installed in the main bore of a dual-lateral horizontal subsea well in the Norwegian Sea. Statoil (now Equinor) has concluded in its 2018 Åsgard Fishbones Drilling Experience Final Evaluation Report that 2/3 of the production is originating from the main bore, i.e. 100% higher production compared to the side-track lateral completed with pre-perforated liner only, based on production log evaluation. The log was run in September 2017, more than two years after production start, proving sustained production benefit by the use of Fishbones technology.
