Basement structure of the Hontomín CO<sub>2</sub> storage site (Spain) determined by integration of microgravity and 3-D seismic data
A multidisciplinary study has been carried out in Hontomín (Spain) to determine the basement structural setting, its geometry and the geometry of the sedimentary succession of an area aimed to be the first Spanish pilot plant for CO<sub>2</sub> storage. An integration of coincident 3-D s...

| description | A multidisciplinary study has been carried out in
Hontomín (Spain) to determine the basement structural setting, its
geometry and the geometry of the sedimentary succession of an area aimed to be the
first Spanish pilot plant for CO<sub>2</sub> storage. An integration of coincident
3-D seismic results, borehole data and unpublished microgravity data were used
to reproduce the deep structure and topography of the basement and to
quantify the thickness of the Triassic Keuper evaporites. The subsurface
structure is characterized by a half-graben setting filled with Keuper
evaporites (up to 2000 m thick), forming an extensional forced fold. All
data sets clearly identify two main fault systems, compartmentalizing the main
structural domain into three differentiated blocks. These faults have been
interpreted to be reactivated normal faults that have led to the formation of
the Hontomín dome. |
