Three-dimensional reconstruction of geological surfaces: An example of growth strata and turbidite systems from the Ainsa basin (Pyrenees, Spain)

The external and internal geometry of four turbidite systems outcropping around the Buil syncline (Ainsa basin, Spanish Pyrenees) have been reconstructed with reservoir-scale resolution in three dimensions. The irregular geometry of the syncline and the resolution required for the reconstruction can...

Sumario:The external and internal geometry of four turbidite systems outcropping around the Buil syncline (Ainsa basin, Spanish Pyrenees) have been reconstructed with reservoir-scale resolution in three dimensions. The irregular geometry of the syncline and the resolution required for the reconstruction cannot be resolved with cross-sections. Therefore reconstruction has been carried out with a new methodology that applies a 3-D dip-domain geometrical model and 3-D restoration techniques to achieve reservoir-scale resolution in kilometric-scale reconstructions. This methodology is aimed at resolving 3-D geometries in folded areas, and regions with variable thickness stratigraphy.</p><p>The 3-D reconstruction of the Buil syncline reveals the synsedimentary growth of an intrabasinal anticline and the foreland lithospheric flexure associated to tectonic loading north of the Ainsa basin.
