Klausen, Tore Grane; Rismyhr, Bjarte; Müller, Reidar; Olaussen, Snorre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A change to more sandstone dominated deposits and increasing condensation across the Triassic–Jurassic boundary is generally associated with improved reservoir quality in the Barents Sea. However, spatial and temporal ...
