D4.3 Final concept description and preliminary consideration by regions.

The objective of the WP4 is to provide and analyse available information on the optimum development concept applicable to the proposed pilots of the Paris Basin (FR), the Lusitanian Basin (PT), and the Ebro Basin (ES) to go ahead with the decision of whether these pilots are viable technically and commercially, considering social and environmental demands, and in the existing European and local regulatory frame. As it is described in D4.1 Methodology for alternatives definition, prioritisation, and selection; D4.2 Conceptual scenarios definition to enable decision support, and D4.9 Economic evaluation of alternatives and prioritisation results, each region has defined selected scenarios, reviewed them, and carried out a techno-economic evaluation, selecting the optimum development scenario for each region, i.e., Paris Basin, Lusitania Basin, and Ebro Basin; and, more general approach for Silesia Basin and Macedonia Basin. Those selected developments will be optimized during next months, being the basis for the final investment decision report. This deliverable describes from a technical point of view the selected scenario for each region as astarting point for the next phase of project definition.
