Excess natural gas is being flared, or burnt off, at a flare stack at the refinery in Tula November 21, 2013. Mexico's oil refining industry, saddled for years with bloated costs, chronic underinvestment and generous government fuel subsidies, ought to be on the verge of a bright new dawn. A shake-up last month dismantled the state-run Pemex oil and gas monopoly, ending decades of stubborn self-reliance and potentially opening the door to foreign oil companies.
