Ultra Petroleum’s primary asset is the robust, long life, tight-gas sand resource play in the Green River Basin of Wyoming.
The Pinedale and Jonah Fields are two of the largest natural gas fields in the United States, where Ultra is in the early stages of development of a world-class legacy asset with over a twenty-year drilling inventory of wells. Over 75 percent of the growth still lies ahead of the Company. In addition to its dominant position in Wyoming, Ultra Petroleum is currently in the early development stage in the Northeast, focusing on the Marcellus Shale in the Appalachian Basin of Pennsylvania. With the knowledge and experience gained from its unrivaled acreage holdings across the entire Pinedale and Jonah Fields, Ultra Petroleum is uniquely positioned to unlock the potential of this new shale play. Ultra intends to leverage this advantage to capture incremental value from its acreage holdings across Pennsylvania.
