Complete exploitation of the Elk Hills oil field in Kern County depends upon a ready supply of sequestered carbon dioxide, according to Oxy, the primary producer in the field. Oxy submitted a presentation on its plan to inject the greenhouse gas into the oil field in the context of a California Energy Commission proceeding to license a coal power plant in the area outfitted for carbon capture and sequestration. It\u2019s known as Hydrogen Energy of California. Oxy has been injecting water into the 100-year-old oil field to keep up enough pressure to continue to produce oil, the company told the California Energy Commission June 26. However, the water forces out only oil trapped in large spaces in the underground oil-bearing formation. Using water alone, production would continue to decline in the field, even though large amounts of oil would still be trapped in small pores in the formation. According to Oxy, injecting CO2 can force oil out of those small interstices, allowing greater recovery from the field. Oxy said it would use a water \u201cchaser\u201d after injecting batches of CO2 to help hold the greenhouse gas in place. Water helps do that, it said, because some of the CO2 dissolves into the liquid preventing it from finding its way to the surface to enter the atmosphere. Oxy notes that it\u2019s been injecting CO2 successfully at enhanced oil recovery projects in other areas for the past 35 years to help boost production of oil to burn as fuel. * * * * * With recent headlines warning of hotter summers ahead, California\u2019s Climate Action Team Public Health Work Group is planning to meet July 9 to dust off and discuss the state\u2019s heat adaptation guidance. The guidance--which consists of an emergency response plan by the California Emergency Management Agency--calls for state and local agencies to cooperate to alert residents to the health dangers of heat storms, to open cooling centers during hot spells, and to check up on and transport high risk people to those centers as needed. State and local agencies are seeking to partner with utilities in administering the plan. At a minimum, it requires utilities not to cut power to designated cooling centers if they need to shed load during a stage three power emergency. The plan, which seeks to use non-profits to help transport vulnerable residents to cooling centers, deals with potentially unpleasant details like whether and how to handle the need for forced entries when they do not respond to a knock at the door. * * * * * Sustained. That\u2019s the effect of a federal court action June 26 on U.S. Environmental Protection Agency rules to control greenhouse gases. In a consolidated ruling, U.S. Court of Appeals for the District of Columbia Circuit dismissed several lawsuits brought by numerous states and industry groups challenging the agency\u2019s legal authority. \u201cThese rulings clear the way for EPA to keep moving forward under the Clean Air Act to limit carbon pollution from motor vehicles, new power plants, and other big industrial sources,\u201d said David Doniger, senior attorney for the Natural Resources Defense Council. With the ruling in hand, EPA is expected to complete a rulemaking that would ban new coal power plants unless they\u2019re outfitted with carbon capture and sequestration.
