The result of the propagation of K in the block 9 of Ballena (average map of K for each stratigraphic interval). Observe that the general distribution of K is different in the marine and in the fluvial intervals. Both intervals allow us to predict at least 3 different qualities in reservoir performance (flow units?) for each main domain (marine and fluvial). It is also observed that in the fluvial interval the number of samples of higher permeability is small. The preliminary petrographic analysis suggests that this is the result of the presence of very thin layers, probably of great horizontal continuity.
