Plan view, cross section, and stratigraphy of the Troll field. Located in the Horda platform area, the field consists of three main fault-bound compartments in which oil and gas is hosted by Upper Jurassic shallow-marine reservoirs belonging to the Viking Group (Holgate et al., 2013). As well as being the largest discovery in the North Sea rift, the neighboring license forms Norway’s first Carbon Storage Exploration License (EL 001), which will see injection into the Lower Jurassic Johansen Formation (Fm). CCUS = exploratory carbon capture, utilization and storage well; Grp = Group; MFS = maximum flooding surface; MSL = mean sea level; SYS. = system.
