Hand drawn picture showing the Devonian, Montoya, and Ellenburger formations in
different colors. Each layer contains small vertical lines representing
fractures in the earth. Porosity pods are represented by stippled ovals drawn in
the layers. A vertical well is drawn through the layers to show that it missed
all of the porosity pods and fractures. A horizontal well is drawn to represent
the ability to penetrate numerous porosity pods and fractures throughout the
formation thereby optimizing the well.
