July 2 (Reuters) - The following table shows crude oil output by the Organization of the Petroleum Exporting Countries in millions of barrels per day (bpd) in June and May, according to a Reuters survey published on Monday. At a June 22 meeting, OPEC agreed to boost output by returning to 100 percent compliance with oil output cuts that took effect in January 2017, after months of underproduction by countries including Venezuela and Angola. Saudi Arabia said the move would translate into an output rise of around 1 million barrels per day (bpd). The June survey indicates that output from the 12 OPEC members with supply reduction targets under the deal rose by 680,000 bpd compared to May. Total OPEC output increased by 320,000 bpd. Compared with levels from which they agreed to cut, which in most cases was October 2016 output, the 12 members as a group have reduced production by 1.288 million bpd. Given the pledged reductions total 1.176 million bpd, that equates to 110 percent compliance, down from 167 percent in May. Congo Republic joined OPEC with immediate effect at the June 22 meeting. The country will be added to the Reuters survey from July. May's production total was not revised.

Reuters has used this target (178,000 bpd) and pledged cut given by an OPEC delegate (12,000 bpd) to calculate a supply cut baseline of 190,000 bpd. The Reuters survey aims to assess crude supply to market, defined to exclude movements to, but not sales from, storage. Saudi and Kuwaiti data includes the Neutral Zone. Venezuelan data includes upgraded synthetic oil. Nigerian output includes the Agbami stream and excludes Akpo condensate. (Additional reporting by Rania El Gamal in Dubai; Editing by David Evans)
