The research focusses on the Upper Permian Wegener Halvø Formation. Core 303129 is selected to mainly represent the limestone and its diagenetic modification within this area. Since core 303129 is limited to 53 m depth, core 303137 is taken as a supplementary core to represent the deeper limestone characteristics of Wegener Halvø Formation. Core logging, petrography which includes microscopy, carbonate staining, and cathodoluminescence are methods integrated in this research. In addition, micro-computerized tomography (micro-CT) is added to visualize the porosity in 3D in the deeper part of the core. Based on the observations and findings, this thesis produced a paragenesis which points out the stages such as early and late diagenetic, fracturing and veining, hydrocarbon migration, ore and hydrothermal mineralization, and telogenetic alteration. Identification of hydrothermal mineralization confirmed that there were hydrothermal processes involved. The findings revealed that the carbonate depositional texture and features has suitable reservoir characteristics as also reflected by previously generated hydrocarbon migration. However, due to diagenetic alteration, whereby the cementation reduces the porosity drastically after post-hydrocarbon migration, the carbonate build-up has today no longer a viable hydrocarbon reservoir potential.
