T he Bight Basin is a major frontier basin of Jurassic–Cretaceous age, which is currently undergoing renewed exploration interest. Although only limited data is available for understanding the petroleum systems in the basin, several observations indicate that poor fault seal integrity may represent a key exploration risk. The presence of a paleo-oil column in the Jerboa-1 well, interpreted gas ...

Image logs of 13 wells in the Rag Sefid Anticline show two systems of fractures developed under two deformation phase in the Dezful Embayment. This deformation phases are folding resulted from Zagros NE contraction and reactivation of the basement fault rotated the fold axial trace within the Hendijan-Izeh fault zone. Folding phase comprises four sets of fractures, which include axial and cross...

The Cabuérniga Fault System (CFS) extends for 150 km in E–W trend along the northern divide of Cantabrian Mountains, near Sea. This fault system was reactivated several times since Paleozoic, and displays hydrothermal activity nowadays. We present here a detailed geological map whole CFS six cross-sections distributed strike, which allowed us to unravel kinematic history individual segments com...

S U M M A R Y A number of field observations suggest that sliding on fault planes may occur at very shallow dip in the brittle field. The existence of active low angle normal faults is much debated because (1) the classical theory of fault mechanics implies that faults are locked when the dip is less than 30 and (2) shallow dipping fault planes do not produce large earthquakes (M > 5.5). To rec...

The combination of seismic analysis with advanced physics-based simulation provides an opportunity to further understand injection-induced fault reactivation, including the hydro-mechanical interplay between different faults and rock where they reside. Here, this is investigated based on data from hydraulic stimulation a well at Reykjanes geothermal field. Central development interdisciplinary ...
