Unconventional oil and natural gas liquids will account for 9.2 million barrels per day or 35% of the total increase in liquids production in the reference case by 2035, according to the U.S. Energy Information Administration's (EIA) "International Energy Outlook 2011," released in mid-September. Unconventional natural gas production is predicted to rise from 14 trillion cubic feet (Tcf) in 2008 to 43 Tcf in 2035. "High oil prices, improvements in exploration and extraction technologies, emphasis on recovery efficiency, and the emergence and continued growth of unconventional resource production are the primary factors supporting the growth of non-OPEC liquids production in the reference case," according to the report.
