A Historical Perspective of Anadarko's CBNG Exploration and Development Success in the Rocky Mountain Region
Anadarko Petroleum has been actively exploring and developing

The second play type is represented by the County Line Field, consisting of the Big Mike and Big George Federal Units located in the central Powder River Basin of Wyoming. These areas were identified in the mid- 90's and currently under field development. This play type is characterized by low gas content sub-bituminous coal seam with thicknesses exceeding 100' at average depths of 1100'. Wells are completed open-hole with common water rates of 700 to 1200 BWPD. Critical to these play types are strategies for managing produced water. Various methods such as under ground injection, surface impoundments, irrigation utilization and aquifer recharge are employed in the Anadarko projects.
Anadarko continues its exploration efforts on the Wyoming Land Grant utilizing the experience and knowledge gained in success of previous play types.
