Establishment of robust reservoir models and estimates of subsurface hydrocarbon volumes in relatively unknown subsurface settings can be improved by using data from field analogues. The discovery of the Rosebank oilfield in the Faroe–Shetland Basin showed that intrabasaltic sandstones can form important hydrocarbon reservoirs in volcanic basins (Helland-Hansen 2009). The Sødalen region in southern East Greenland (Fig. 1) forms an excellent field analogue to the Rosebank oilfield where contemporaneous Palaeogene sediments interbedded with lava units can be studied and sampled (Larsen et al. 1999). In this area many of the exposures are located along steep, inaccessible cliffs with excellent exposures that are ideal for 3-D photogeological studies based on digital high-resolution photographs taken from a helicopter.

Summary The modeling of ordered sedimentary cycles through orbital forcing (cyclo-stratigraphy) could impact the Middle East E&P industry practices from regional exploration to reservoir engineering. The correlation of longer period cycles could detect thinning or disappearing reservoir intervals over structures. These terminations may be due to erosion or non-deposition, and used to guide exploration for stratigraphic traps. The correlation of shorter period cycles may be used to map the disappearance or diagenetic alteration of reservoir flow units between wells. The Permian and Mesozoic carbonates and evaporites that constitute the main Middle East hydrocarbon reservoirs and seals, manifest cycles at many scales, and are particularly suited for cyclo-stratigraphic analysis.
