The Triassic – Early Jurassic of the northern Barents Shelf: a regional understanding of the Longyearbyen CO2 reservoir
We address the spatial and temporal development during the Triassic to Middle Jurassic of the NW Barents Shelf in order to provide a regional framework for the targeted reservoir of the Longyearbyen CO2 Lab. The reservoir is Middle Triassic to Middle Jurassic stacked sandstones at a depth of 670–970...
