Global gas reserves increase - BP
Myanmar (+0.7 tcm) and China (+0.6 tcm) were the main contributors to growth.
By region, the Middle East holds the largest proved reserves (79.4 tcm, 42.5 percent of the global total), while by country, Iran is the largest reserve holder (33.5 tcm, 18 percent total).
Global gas production was essentially flat (0.3 percent, 21 bcm increase) in 2016, the weakest growth in gas output for 34 years, other than in the immediate aftermath of the financial crisis. Production hit almost 3.552 tcm in the reporting period. Declining production in North America (-21 bcm) partially offset strong growth from Australia (19 bcm) and Iran (13 bcm).
