(Adds details, background) MOSCOW, Aug 2 (Reuters) - Russian oil output rose by 150,000 barrels per day (bpd) in July from a month earlier, surpassing the amount Moscow had promised to add following a meeting among global oil producers in Vienna in June, Energy Ministry data showed on Thursday. Under an initial deal between OPEC and non-OPEC producers, Moscow had agreed to cut 300,000 bpd from the production level of 11.247 million bpd attained in October 2016 by Russia. After oil prices subsequently rose, the OPEC and non-OPEC producers decided on June 22 in Vienna to increase their combined production by 1 million bpd, of which Russia was to contribute 200,000 bpd starting on July 1. According to the Energy Ministry data, Russian oil production rose to 47.429 million tonnes in July versus 45.276 million in June. In barrel terms, output reached 11.21 million bpd, up from 11.06 million bpd in June. That brings the combined Russian increase to 263,000 bpd compared to the initial cut agreed two years ago. Russian Energy Minister Alexander Novak said on Wednesday that higher production by Moscow was aimed at "maintaining stability of the (global) oil market within the framework of joint actions of OPEC and non-OPEC countries." Initially, OPEC and non-OPEC producers agreed on a combined reduction of 1.8 million bpd. However, lower production by a number of countries deepened the cuts, raising fears of global oil shortages and a potential spike in oil prices. At the June 22 meeting, OPEC agreed to boost output by returning to 100 percent compliance with the oil output cuts that took effect in January 2017, after months of underproduction by countries including Venezuela and Angola. Last week, Novak said Russia planned to increase its production by 200,000-250,000 bpd and that the OPEC+ group led the current deal. The Energy Ministry also said gas production in July came to 53.92 billion cubic meters (bcm), or 1.74 bcm a day, versus
53.57 bcm in June. On Wednesday, Russia's Gazprom said
separately its gas production last month was at 36 bcm.
