Even so, OPEC said it would tread cautiously. The organization forecast that 2019 oil consumption will rise 1.14 million b/d year-on-year, a downward revision of 70,000 b/d from last month's report, as "significant downside risks from escalating trade disputes spilling over to global demand growth remain."

Total world crude oil production increased sharply in 2018 by 1.213 million barrels/day (mb/d), or 1.6%, as compared to 2017, to reach 75.78 mb/d, marking a historical high and the highest annual growth since 2015.

Saudi Arabia produced 9.65 million barrels per day (bpd) of oil in May, a Saudi industry source said, a deeper cut than its target set by the Organization of the Petroleum Exporting Countries and allies including Russia, a group known as OPEC+.

The production fall resulted mainly from the closure due to oil contamination of Russia’s Druzhba pipeline, which usually ships 1 million bpd, or 1 percent of global oil demand.

In March 2019, for the 23rd consecutive month, dry natural gas production increased year to year for the month. The preliminary level for dry natural gas production in March 2019 was 2,771 billion cubic feet (Bcf), or 89.4 Bcf/d. This level was 9.2 Bcf/d (11.5%) higher than the March 2018 level of 80.2 Bcf/d.

UK oil production rose by nearly 9% on the year in the first quarter of 2019 to 1.18 million b/d, continuing a half-decade revival and beating industry expectations, government statistics released Thursday showed.

To put these two things together, the shale oil affecting both the volume of export and the price, plus the developments in clean technologies, tell me that for those countries who meet in Vienna, it has never been more important for them to diversify their economies. We have seen in Algeria, for example, one of the main reasons is the low oil price and the impact on the economy, and the same with Venezuela and elsewhere.

Russia’s recent oil output is below the 11.18 billion bpd target Moscow has pledged as part of an international deal among producers to curb production to support prices.

Brazil has seen its exports of crude grow from 734,000 b/d in 2015 to 1.3 million b/d in Q1 of this year. In contrast, Mexico, which was once a powerhouse of oil production, has maintained its export status only through curtailment of domestic refining, not increased crude oil output.

Although compliance to the cuts had a slow start, OPEC's JMMC noted in a press release following their meeting in Jeddah, Saudi Arabia, that compliance had hit a record high of 168% in April 2019. Average conformity reached 120% since January 2019.
