Kinder Morgan officials plan to invest more than $670 million to grow the company’s carbon-dioxide infrastructure in Southwest Colorado and New Mexico.

The company’s plan, announced this week, includes expanding its carbon-dioxide production operations in the Cow Canyon area of the McElmo Dome source field in Montezuma County. Capital expenditures for the Cow Canyon development are estimated at approximately $344 million, and it would increase carbon-dioxide production in the McElmo Dome source field by 200 million cubic feet per day by the end of 2015, according to a company news release.

In Montezuma County, the plan includes ongoing 3-D seismic acquisition, 16 new wells, activation of one production well and one produced water-disposal well, water-separation facilities, one central compressor station, and associated gathering and produced-water disposal pipelines, the company said.

Capital expenditures for the Cortez Pipeline expansion are estimated at approximately $327 million, and that would increase the pipeline’s capacity from 1.35 billion cubic feet per day to 2 billion cubic feet per day.

Known as enhanced oil recovery, the carbon dioxide is piped to west Texas and southern Utah oil fields, where it is pumped into near-depleted wells to extract more oil.

With a combined enterprise value of approximately $100 billion, Kinder Morgan owns an interest in or operates approximately 80,000 miles of pipelines and 180 terminals.

Kinder Morgan pipelines transport natural gas, gasoline, crude oil, carbon dioxide and other products, and its terminals store petroleum products and chemicals and handle such products as ethanol, coal, petroleum coke and steel.
