11. The territory subject to an exploration, production or storage licence or to an authorization to produce brine is limited on the surface by its perimeter, and in depth by the vertical projection of its perimeter.
For a storage licence, the territory is determined by the vertical projection, on the surface, of the perimeter of the underground reservoir and the perimeter of the protected area. The Government determines the size of the protected area by regulation.
The size of an underground reservoir is determined on the basis of the assumption that a reservoir is limited at the top and base by stratigraphic geological units.
