Deliverable 4.1 - Geological model, Danish site

This report describes the update of the Vedsted site model from previous studies (Frykman et al. 2008, 2011) in order to conduct a site characterization that will allow the development of a dry-run licence application. The updated model covers a larger area of 50x50 km, and includes both the total overburden layers and some of the underburden. The request for a larger site model is due to the work on geo-mechanical modeling focusing on the pressure propagation and stress changes during the injection period. The larger model size and requirements for future computations have led to simplification of parts of the model, e.g. leaving out all the faults on the center of the structure that were incorporated in the previous more detailed site models. It is assumed that the work with fault features in this geo-mechanical model will incorporate the faults as very simple vertical elements with contrasting properties as proxies for any faults. The model area covers 50 x 50 km, centered on the main structure closure around the existing Vedsted-1 well. The present geo-model is produced in a regular grid, and will most probably need some re-gridding before optimal flow simulations can be designed for the investigations.
