Figure 3. Anomalous discontinuities in red. Venezuela’s increase was due to the inclusion of heavy Orinoco oil, to be properly classified as non-conventional. It prompted a reaction by other OPEC countries in the "quota wars". Iraq’s 1983 increase was the late reporting of the East Baghdad Field found in the 1978. Unchanged reports are implausible, irrespective of the amount. Petroconsultants estimate is based on the sum of individual fields.
