Global SEEBASE® is an integrated basement model that provides foundation knowledge for bottom-up basin analysis and innovation in exploration across the world.
A comprehensive and interpretative sub-surface view of the World that provides an understanding of the shape, depth, structural style and tectonic setting of global basin systems.
Global SEEBASE® draws together over 20 years of the technical work, knowledge and experience of structural geologists, geophysicists, plate modellers, basin analysts and spatial data experts.
Full Scientific and Technical Support offered to assist with installation and understanding of the Global SEEBASE Module.
Available as a single global dataset or in pre-defined regional sub-sets. Clients can also request a customised geographic subset of Global SEEBASE that meets your exploration interests.
Datasets Included in Global SEEBASE®
SEEBASE® Depth to Basement is developed with a specialised 2D/3D workflow based on the integration, interpretation and calibration of a range of geophysical and geological datasets.
Total Sediment thickness derived from SEEBASE® Depth to Basement.
The SEEBASE® Interpretation Confidence Map provides a vector GIS‐based overlay capturing variable confidence and key factors affecting the interpretation of the SEEBASE® surface in any area.
The SEEBASE® Basement Outcrop layer is a compilation of mapped areas of outcropping basement derived from digital maps and literature.
Depth to Moho is supported by 10+ years of existing interpretation and draws on our experience in the interpretation of gravity data calibrated with published models, seismic constraints and crustal-scale modelling.
High resolution basement thickness derived from Depth to Moho.
A detailed, globally consistent basement terrane interpretation, supported by extensive attributes including detailed abstract and references, megaterrane, terrane type, minimum, maximum and basement age.
Basin outlines interpreted using the SEEBASE® Depth to Basement and attributed for Basin Setting and Basin Type.
Choose your delivery:
Global: Full SEEBASE module
Regional: Pre-defined regional subsets
Custom: Select your area-of-interest
GIS product delivery can be customised as needed with projection and data translation available as part of installation support.
Can I upgrade or customise my area-of-interest?
Absolutely. Geognostics has constructed the Global SEEBASE using open-file datasets, publications, reports and other data.
Geognostics also undertakes confidential Client-specific studies that fully integrate Client datasets and knowledge in areas of focused or ongoing interest. We encourage explorers to customise the SEEBASE to incorporate their datasets and knowledge, so that it forms a reliable, foundation layer in your exploration workflow.
Options for custom studies include upgrades to the resolution and confidence of the SEEBASE® Depth to Basement model, structural and tectonic framework studies, heat-flow studies (including geothermal potential), basin and petroleum systems analysis, paleogeography and risk assessment.
Please contact us to scope further work to customise the Global SEEBASE delivery.

Accumulations data supplied by Mapstand
Looking NW through the North Sea towards the Norwegian Sea
The Global SEEBASE shows the strong basement controls on source kitchens and hydrocarbon accumulations throughout the North Sea region and beyond.
Hyperextension is apparent in the broad, deeper depocentres of the More and Voring basins. All hydrocarbon accumulations are shown in red to enhance visability against the SEEBASE. So much discovered, yet so much to explore.
Northern South America
Global SEEBASE image showing the thinned crust underlying offshore Guyana-Suriname - one of the most successful regions for hydrocarbon discoveries since 2015.
World-class Late Cretaceous source rocks are present in the trough that extend along the Guyana margin, and westward into Venezuela where source rocks range from Jurassic to Miocene. The prominence of the arc along the margin of the Caribbean Plate is also evident. All hydrocarbon accumulations are shown in red to enhance visibility against the SEEBASE.
Sea of Okhotsk
Global SEEBASE showing the tectonic setting of the Sea of Okhotsk between Sakhalin Island and the Kamchatka Peninsula. Here, trench roll-back is actively forming extensional basins in a retro-back-arc setting from the Upper Paleocene to the present.
Strong basement controls at terrane boundaries are observed in the region of Sakhalin Island. All hydrocarbon accumulations are shown in red to enhance visibility again the SEEBASE.
