North Halten Terrace and Helgeland Basin Stratigraphic Database

The aim of the North Halten Terrace and Helgeland Basin Stratigraphic Database is to provide a dataset that enhances the stratigraphic understanding of the area and draws upon both the Haltenbanken study, completed in 2010 and the Nordland Stratigraphic Database, completed in 2009.

The upgrade study includes wells from the, Halten Terrace, Donna Terrace, Træna Basin, Nordland Ridge and Helgeland Basin. These structural elements have played an important role in the distribution and preservation of the Tertiary, Cretaceous and Jurassic reservoir sands and this will be presented within the study.

The database comprises a 50 well dataset covering the full stratigraphic section from Tertiary – Triassic. The study utilises the Ichron sequences which are calibrated with the Mid Norway lithostratigraphic nomenclature and also incorporates the Norlex terminology for the Cretaceous sands.
