SEEBASE^®

SEEBASE is an integrated, spatially-continuous, fully attributed, basement model that defines the 3D geometry of basement and provides insights into the structural style and tectonic setting of basin systems and basement geology. The characteristics of basement provide first-order controls on the architecture of an evolving basin.

Geognostics are experts in the interpretation of basement and basin geology specialising in an integrated ‘bottom-up’ approach to understanding crustal and basement structure, tectonics, basement terranes and composition, encapsulated in the SEEBASE® workflow and resulting model.

SEEBASE is developed through the iterative integration, interpretation and calibration of a range of geophysical and geological datasets. The SEEBASE® model can be updated as new datasets are acquired or become available.

SEEBASE workflow steps include:

• Literature, (Client and/or in-house) knowledge and technical expertise

• State-of-the-art geophysical processing, enhancements and imaging of potential field datasets

• Assessment and integration of crustal architecture

• Interpretation of geological sources of gravity and magnetic anomalies

• Interpret basement terranes including their age, nature and boundaries

• Plate reconstructions leveraging the Geognostics GEM Tectonic Module and review of available third-party literature.

• Integration of tectonic events and structural responses to define basement and basin evolution

• Identification of major structures and active faults through time

• Gravity and magnetic modelling

• Depth calibration of interpreted basement to seismic, wells, outcrop, published cross-sections

SEEBASE is available as part of Global SEEBASE or as tailored client studies.

SEEBASE Depth to Basement is a hand-contoured surface integrating potential field interpretation and calibration from seismic, wells and literature.
