Chevron and Exxon courted by fracking firm Sonatrach

ALGERIA - DECEMBER 14: An employee walks in front of a gas flare at the In Salah Gas (ISG) Krechba Project, run by Sonatrach, British Petroleum (BP), and StatoilHydro, in the Sahara desert near In Salah, Algeria, on Sunday, Dec. 14, 2008. From produced gas, the carbon capture plant, the largest and first of its kind, removes annually the carbon dioxide emissions equivalent of 200,000 automobiles running 30,000 kilometers. The CO2 is then reinjected into a two-kilometer deep reservoir instead of the atmosphere, with the intention of storing it perpetually. (Photo by Adam Berry/Bloomberg via Getty Images)
