The Russian camp was locked in negotiations with the Saudis, Qataris and Venezuelans — a core group that had first backed the freeze in February.

Thousands of workers in six oil and petrochemical companies went on strike Sunday to protest proposed government cutbacks.

Industrial production—a broad gauge of output across U.S. factories, mines and power plants—decreased a seasonally adjusted 0.6% in March from the prior month, the Federal Reserve said Friday. Output has fallen for six of the past seven months. From a year earlier, industrial production decreased 2% in March. Manufacturing output, the largest component of the index, fell 0.3% in March.

Some 18 OPEC and non-OPEC countries, including Russia, had been meant to meet on Sunday morning in the Qatari capital of Doha and rubber-stamp a deal - in the making since February - to freeze output at January levels until October 2016.

Gas output from the top seven shale deposits will fall by 1.1 percent to 45.93 billion cubic feet a day from April, the biggest percentage decline since March 2013. The retreat is led by the oil-rich Eagle Ford deposit in Texas and the Niobrara shale in Colorado and neighboring states, where gas is pumped as a byproduct of crude extraction.

Crude oil production in May from the seven major US shale regions is expected to fall 114,000 b/d month-over-month to 4.84 million b/d, according to the US Energy Information Administration’s latest Drilling Productivity Report (DPR).

U.S. crude oil production from the Lower 48 states from new wells (drilled since the start of 2014) made up 48% of total U.S. crude oil production in 2015, up from 22% in 2007. Production from new wells has grown as advances in horizontal drilling and completion techniques led to growth in oil production from low-permeability tight reservoirs. In 2015, production from tight formations—which include, but are not limited to, shale plays—accounted for more than 4 million barrels per day (b/d), or 50% of total U.S. oil production.

The U.K. is the second-largest liquids producer in Europe (after Norway), producing one million b/d in 2015. This amount is large among European countries but small in the global market, and the U.K. remains a net importer of petroleum and other liquids. More than 97% of its liquids production in 2015 came from offshore fields, where petroleum development projects have long lead times. The majority of the offshore crude and condensate fields that began production in 2015 were approved in 2012 or earlier when oil prices were much higher.

U.S. monthly crude oil production in December 2015 continued to decline, as oil production reached its lowest level since November 2014. Production also declined from year-ago levels for the first time in more than four years. This continued production decline is the result of lower crude prices, which have declined more than 70% since the summer of 2014.

Crude oil production in April from the seven major US shale regions is expected to fall 106,000 b/d to 4.87 million b/d, according to the US Energy Information Administration’s latest Drilling Productivity Report (DPR). That includes a 4,000-b/d drop in the Permian to 2.04 million b/d.
