Pinedale and Jonah Fields in southwest Wyoming’s Green River Basin are two of the largest natural gas fields in the United States. Ultra is in the development stage of this world-class legacy asset. The company also has an oil development underway in Three Rivers Field in the Uinta Basin of northeast Utah. Like Pinedale and Jonah, Three Rivers is also a tight-sand play that fits well with Ultra’s strategic core competencies.
