The overpressure variation in the Cenozoic to Jurassic succession northern part of Danish Central Graben may broadly be divided into three major compartments: An upper hydrostatically pressured unit comprises post-mid Miocene recent down ∼ 1200 m depth North and 700 South Graben. second compartment mid-Miocene smectite rich clays including Cretaceous chalk. There, Paleogene Lower provides seal....

Impact of Induced Thermal Stresses during Circulation Tests in an Engineered Fractured Geothermal Reservoir: Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France — The wider concept of hot fractured rock geothermal energy is put forward to overcome the natural limitations of classic geothermal fields. A suite of numerical modules based on a disc...

Image logs and the continuous coring of 8 geothermal wells in Central Upper Rhine Graben (URG) are used for structural characterization 3 reservoirs at Soultz-sous-Forêts, Rittershoffen Illkirch (France). The naturally permeable fracture zones (FZs) hard rocks targets these wells. Subvertical natural networks striking NNW-SSE to N–S granite (inherited from late-Variscan orogeny) N–S/NNE-SSW sed...

We used teleseismic receiver function analysis to image the crustal structure beneath 24 broadband seismic stations densely deployed along two profiles traversing different structural units across western Afar margin. Our high-resolution results pronounced spatial variations in and provide improved insights understand how strain is partitioned crust during rifting. Beneath plateau next northern...
