Facts:

Anadarko’s enhanced oil recovery (EOR) operations in the Salt Creek field of Wyoming utilize CO2 to stimulate oil production from a 100-year-old field. The CO2 injected into the ground enhances domestic oil production and prevents a greenhouse gas from being emitted into the atmosphere. The Salt Creek field is said to be one of the largest CO2 oil recovery and geological-sequestration projects of its kind in North America. The project currently sequesters enough CO2 each day to offset the equivalent emissions of more than half a million cars. That is around 125 million cubic feet of carbon dioxide a day and 181 billion cubic tonnes as of February 2010.

Anadarko buys the carbon dioxide for its Salt Creek project as a byproduct from natural gas and helium production at ExxonMobil’s LaBarge field, some miles to the west of Casper, Wyoming. Anadarko will operate under the name of its now wholly-owned subsidiary Howell Corp

The region has a pipeline infrastructure, mostly in place since the 1980s, for transporting carbon dioxide from LaBarge.  Anadarko had only to construct a spur line from that existing infrastructure.

In 2003 Anadarko laid 125 miles of 16-inch pipeline that took it from roughly the middle part of the state, which was the terminus of ExxonMobil’s line, and took that carbon dioxide up to the Salt Creek field.
