The Barents Sea of the Norwegian Continental Shelf: drilling through carbonates, modelling, risk management and well planning
Abstract There are a number of geological and hydrogeochemical modelling techniques used in order to ascertain formation of the hydrogen sulphide (H 2 S) in the formation fluid within a geological setting in several blocks of the Norwegian Barents Sea. Careful consideration of the regional and chemi...
