Since its inception in March 2002, Bill Barrett Corporation has assembled a portfolio of development and exploratory properti ... es in the Rocky Mountain region of the United States. We began active natural gas and oil operations in March 2002 with the acquisition of properties in the Wind River Basin. Initially, we increased our activity level and the number of properties that we operate by acquiring a large inventory of undeveloped leasehold interests through federal and state sales as well as private purchases and trades. We also acquired producing properties that had large undeveloped acreage positions associated with them. For example, in 2002, we completed two additional acquisitions that included properties in the Uinta, Wind River, Powder River and Williston Basins; in early 2003, we completed an acquisition of largely undeveloped coalbed methane properties located in the Powder River Basin; in September 2004, we acquired interests in properties in the Piceance Basin in and around the Gibson Gulch field; and in May 2006, we added to our coalbed methane position in the Powder River Basin. In June 2007, we sold our Williston Basin properties. In June 2009, we acquired Cottonwood Gulch, an undeveloped property in the Piceance Basin. With asset sales of the Piceance Basin and the majority of the Powder River Basin in late 2014, we have trimmed our portfolio to focus on two high-return, oil-growth assets located in the Denver-Julesburg Basin, Colorado and the Uinta Basin, Utah. read more
