Ventana is focused in the STACK, Merge, and SCOOP plays of the eastern Anadarko Basin in central Oklahoma. These three plays include multiple vertically stacked oil-prone reservoirs such as the Oswego, Springer, Meramec, Osage, Sycamore, and Woodford formations. The Woodford formation is one of the highest quality source rocks in the US, as well as prolific unconventional reservoir.
