据普氏能源资讯5月20日东京报道，里海哈沙克斯坦段卡沙甘（Kashagan )油田的一名合作伙伴周一在标准普尔普氏全球能源资讯上表示，完成定期维护后，该油田周日重启生产。
一位来自东亚的消息人士表示，在全球石油市场供不应求之际，哈萨克斯坦轻甜CPC混合原油的买家对重启这一消息表示欢迎。这位消息人士表示：“在供应紧张的情况下，我们对CPC混合原油作为供应候选品种的供应不断增加表示感谢。”
CPC混合是哈萨克斯坦西部生产的轻质级产品，比重约为44-45API，含硫量为0.5%-0.6%。该等级通过1580公里(合980英里)的CPC管道出口到俄罗斯黑海沿岸Novorossiysk附近的一个出口终端。卡沙甘去年成为CPC混合原油的第二大来源，超过Karachaganak。
今年5月份CPC混合原油的出口可能要开始复苏，由于卡沙甘的维护，4月份的出口量是自2016年10月以来的最低水平。
5月14日，通过北里海Inpex子公司持有卡沙甘7.56%股份的Inpex的一名官员称，卡沙甘油田自4月中旬起维修，持续了45天左右,此前日产量约为34万桶。
5月14日Inpex的一位官员表示，该油田的产量将逐步增加到37万桶/日，但没有给出时间表。
卡沙甘油田的其他合作伙伴有：埃尼（16.81%）、埃克森美孚（16.81%）、KMG（16.87%）、壳牌（16.81%）、Total（16.81%）和CNPC（8.33%）。
由于卡沙甘的维护，哈萨克斯坦4月份原油和凝析油日产量下降27万桶，环比下降14.8%，至156万桶/日。这有助于该国履行减产承诺，根据最新的欧佩克/非欧佩克原油生产协议，将日产量从2018年11月的190万桶削减4万桶。
哈萨克斯坦能源部长卡纳特·博祖巴耶夫(Kanat Bozumbayev)今年早些时候表示，2019年前6个月的平均产量将遵守哈萨克斯坦承诺的日产量降至186万桶，预计3月、4月、5月产量将下降，并可能抵消1月、2月和6月增加的产量。

Kazakhstan's giant Kashagan oil field restarts production: partner
Production at the giant Kashagan oil field in Kazakhstan's sector of the Caspian Sea restarted Sunday following the completion of scheduled maintenance, a source with a partner in the field's development told S&P Global Platts Monday.
A source with an East Asian buyer of Kazakhstan's light sweet CPC Blend crude welcomed the news of the restart amid tightening supply in global oil markets. "Amid tightening supplies, we are grateful for the increasing supply of CPC [Blend crude] as a supply candidate," the source said.
CPC Blend is a light grade produced in western Kazakhstan with a specific gravity of around 44-45 API and a sulfur content of 0.5%-0.6%. The grade is exported through the 1,580 km (980 mile) CPC pipeline to an export terminal near Novorossiysk CPC Blend exports in May will likely start recovering after volumes in April were the lowest for the grade since October 2016 due to the maintenance at Kashagan.
The Kashagan oil field was producing at around 340,000 b/d prior to its about 45-day maintenance from mid-April, an official with Inpex, which holds a 7.56% stake in Kashagan via subsidiary Inpex North Caspian Sea, said Production at the field will be gradually increased to 370,000 b/d, the Inpex official said Other partners in the Kashagan oil field are Eni (16.81%), ExxonMobil (16.81%), KMG (16.87%), Shell (16.81%), Total (16.81%) and CNPC (8.33%).
Kazakhstan's daily crude and condensate production fell by 270,000 b/d or 14.8% month Kazakh energy minister Kanat Bozumbayev said earlier this year that average production over the first six months of 2019 would be in line with Kazakhstan's commitment to reduce output to 1.86 million b/d, forecasting that lower output in March, April and May would compensate for higher output in January, February and June.
