The Jurassic Petroleum System in the Danish Central Graben
2
Aims Establish a consistent seismic-sequence stratigraphic framework of the Jurassic in the Danish Central Graben. Provide a series of paleogeographical maps, showing the depositional environments, distribution of litholo- gies and potential sand source areas through time. Provide an overview of reservoir sandstone charac- teristics, i.e. porosity, permeability, net sand, sedi- ment petrography and diagenetic alterations. Outline the regional variation of source rocks/petroleum characteristics such as quality/type, maturity, likely kitchen areas and migration fairways. Present basin modelling studies in areas where proper source rocks and reservoirs can be anticipated. Present a synthesis of the Jurassic Petroleum System, covering prospectivity and hydrocarbon plays in the Jurassic of in the Danish Central Graben. The study is carried out through collaboration agreements between GEUS and participating Oil Companies. Throughout the project period results will be made accessible to participating Companies through a restricted web-site and discussed during workshops, which are held twice a year. 5°E 4°E 56°N 55°30'N Feda Graben Gertrud Graben Gertrud Graben Heno Plateau Søgne Basin Søgne Basin Søgne Basin Poul Plateau Salt Dome Province Tail End Graben Tail End Graben Tail End Graben Coffee Soil Fault Ringkøbing–Fyn High Hejre-1,-2 Svane-1 Mid Mid North Sea North Sea High High Mid North Sea High Zechstein carbonate oil shows U.

In 2011 the Geological Survey of Denmark andGreenland (GEUS) launched a 3 year project on “The Jurassic Petroleum System in the DanishCentral Graben” financed by oil companies activein Denmark. The short title of the project is PET-SYS (PETroleum SYStem).

ActivitiesThe Study will comprise the following activities:
Activity 1:Establish a GIS platform for presenting study results on arestricted web-site.
Activity 2:Integration of seismic interpretation, stratigraphy andreservoir characterization. Construction of paleogeographicmaps and interpretation of depositional environments.
Activity 3:Evaluation of Jurassic source rock properties and composi-tion of petroleum.
Activity 4:3D basin modelling studies.
Activity 5:Synthesis of activities 2-4.
