Linde North America has upgraded its carbon dioxide (CO2) plants in Corpus Christi, TX, and Woodward, OK, to better serve the Midcontinent and Eagle Ford Shale regions with expanded CO2 availability. “Linde has brought these plants on stream to supply the surging demand for CO2 in the oil and gas industry,” said Lauren Porambo, CO2 product manager. “The use of CO2 in fracturing completions displaces the use of water, reduces formational damage and enhances well production.” CO2 is injected in a liquid state and converts to a gaseous state down-hole, mitigating formational damage and fluid on formation, while enhancing well clean-up and flow-back, Linde said. Conventional liquid pumps are used, so service companies require no specialized equipment.
