So Far, Global Net Exports of Oil Peaked in 2005Because of the way that we define net exports, we have to deal in terms of total petroleum liquids (plus other liquids for the EIA data set).
Some definitions:
Global Net Exports (GNE) = Combined net exports from (2005) Top 33 net oil exporters, total petroleum liquids + other liquids (EIA), which accounted for about 99% of total global net exports of oil in 2005
Available Net Exports (ANE) = GNE less Chindia’s Net Imports (CNI)
CNE = Cumulative Net Exports (for a given time period)
ECI (Export Capacity Index) Ratio = Ratio of production to consumption
GNE/CNI Ratio is analogous to the ECI Ratio
Six Country Case History. The Six Country Case History consists of the major net oil exporters (net exports of 100,000 bpd or more) that hit or approached zero net exports from 1980 to 2010, excluding China. China, like the US, became a net importer prior to a production peak, because of a rapid rate of increase in consumption. Combined production from the Six Countries virtually stopped increasing in 1995, showing only a 2% increase from 1995 to 1999.
The following chart shows the normalized values for production, ECI Ratio, net exports and remaining post-1995 CNE (Cumulative Net Exports) by year (1995 values = 100%).

Note that even as production increased slightly from 1995 to 1999 (by 2%), net exports fell, because of rising consumption, as illustrated by the decline in the ECI Ratio. And note that even as production increased from 1995 to 1999, remaining post-1995 CNE fell by 54%.
Estimated Six Country post-1995 CNE were about 9.0 Gb (billion barrels) based on the 1995 to 2002 rate of decline in their ECI ratio. Actual post-1995 CNE were 7.3 Gb.
The key point is that a declining ECI Ratio corresponded to a rapid rate of depletion in remaining CNE, and even as Six Country production rose from 1995 to 1999, the rate of depletion in remaining post-1995 CNE accelerated, from 15%/year in 1996 to 26%/year in 1999.
Global Net Exports of oil (GNE). GNE, the combined net exports from the top 33 net exporters in 2005, fell from about 46 mbpd (million barrels per day) in 2005 to about 44 mbpd in 2012. Preliminary 2013 data show that GNE in 2013 fell to 43 mbpd. Combined production from the top 33 net exporters in 2005 rose slightly from 2005 to 2013, but because consumption increased faster than production, net exports fell, as evidenced by the decline in the ECI Ratio.
The following chart shows the normalized values for production, ECI Ratio, net exports and estimated remaining post-2005 CNE (Cumulative Net Exports) by year (2005 values = 100%).

Based on the 2005 to 2012 rate of decline in the Top 33 ECI Ratio, I estimate that remaining post-2005 Global CNE fell by about 21% by the end of 2012. As noted above, this methodology was too optimistic for the Six Country Case History, in regard to estimating post-1995 CNE.
Available Net Exports of oil (ANE). ANE are defined as Global Net Exports of oil (GNE) less the Chindia region's (China + India’s) net imports (CNI). ANE, the volume of GNE available to importers other than China and India, fell from 41 mbpd in 2005 to 35 mbpd in 2012. Based on the preliminary 2013 data, ANE fell to 34 mbpd in 2013.
