On 26 September 2017, Hansa Hydrocarbons announced the sidetracked well on the Ruby discovery had been successfully tested and results were positive. The discovery was made in July 2017 in the basal Rotliegendes sandstones and extends across the Dutch and German offshore sectors. It lies in water depths of 28 meters and is located approximately 20 kilometers from the existing subsea tie-in point at the Noordgastransport (NGT) gas export pipeline. This area is set to undergo further exploration and appraisal in 2018 and 2019. Until which time, the true scale and significance of Ruby and the GEms cluster is uncertain. However, these early estimates suggest Ruby, and its neighbouring prospects, hold the potential to transform Dutch offshore production over the next 10 to 15 years.
