University cluster Tectonic models for natural stress

Publieke samenvatting / Public summary

Doelstelling
This project aims to build unifying scenarios for temperature (basin heat flow), burial, exhumation and stress-deformation history of gas shale formations in the Netherlands, which can be used for basin modelling, for in-situ stress modelling and for the pre-drill assessment of geomechanical properties and fractures.

Korte omschrijving
As input public datasets from the mapping of the subsurface of the Netherlands by TNO will be used.

Resultaat
Deliverables of the project will be:
- 4D geomodel, constrained VR and AFT and temperature data. Scenarios for regional heat flow and lithosphere deformation responsible for observed vertical motions
- Rheological reconstruction and scenarios for (paleo)stress
- Analogue (sandbox) deformation models of past stress field and deformation at selected time intervals (including present day)
- Analysis of the effect of reconstructed temperature/stress/deformation time-paths on regional interpretation of mechanical properties and natural fractures, for various shale formations, and its effect on productivity (in close co-operation with other projects in the WP
