KazMunayGas operates 2 oil refineries in Kazakhstan:
KazMunayGas has a US $1.7 billion plan for the modernization of the Atyrau refinery. In August 2012, it obtained a US $297.5 million loan from the Japan Bank for International Cooperation and the Bank of Tokyo Mitsubishi a deep oil refining complex at the Atyrau Oil Refinery. This loan followed a contract awarded to Marubeni to reinforce the production of oil products to suit European environmental standards.
In May 2011 KazMunayGas has been hit by a strike of workers demanding higher wages and better conditions. 
In August, 2011, the company was four months into a wildcat strike at Uzenmunaigas. On August 2, Zhaksylyk Turbaev, a trade union member working for an oilfield service company in Zhanaozen, was killed. On August 24, 2011, the 18-year-old daughter of an elected member of the strike committee was found dead and apparently murdered, according to the striker. Zhansaule Karabalayeva was found in the countryside near the oilfield in Western Kazakhstan with multiple injuries, according to her father, Kurdaibergen Karabalayev, in a telephone interview on August 27. Bulat Abilov, an opposition politician, said "I don't think this is unconnected to the strike." "The local chief of police, quoted in a local paper, said the killing was not related to the strike. The company spokesman declined comment," according to one report.
On August 31, Interior Ministry spokesman Nurdilda Oraz said in the Kazakh capital, Astana, that the police "did not associate" the "common crime" of Karabalayeva's murder with her father's activities. In the same report, the KMG EP press office said the father was not the trade union chairman and had never been a strike activist but worked as an engine driver for the company until July 27 this year.
Also in August, a labor lawyer, Natalya Sokolova, was sentenced to six years in jail for 'organizing illegal gatherings' at the smaller Karazhanbas field, which was also on strike. 
These labour strikes were causing a 6% output drop in KazMunayGas production, according to a company spokesman.
On August 26, KMG EP fired around 900 striking workers and replaced them with new recruits from the area. The company said that production at Uzen had stabilized. Karazhanbasmunai, a joint venture between KMG EP and China’s Citic, also fired around 500 workers.
Until mid-September 2011, daily protests by angry protestors, many of whom used to work at Uzen, continued in Zhanaozen's main square "in a rare display of popular dissent".
The unrest has persisted, with violence erupting on independence day, 16 December 2011, killing 16 and leaving about 100 injured as police opened fire on the demonstrations. Army units and armoured personnel carriers were sent in by the Interior Ministry to quell the ensuing protests, which saw government and Uzenmunaigaz buildings set alight by demonstrators. 
The labor conflict resulted in the resignation of KazMunaiGas EP Chief Executive Officer Askar Balzhanov on Dec. 22. President Nursultan Nazarbayev also replaced the head of parent company KazMunaiGaz National Co., Bolat Akchulakov, and fired his own son-in-law Timur Kulibayev, who headed the country’s sovereign-wealth fund.
