据能源世界网11月30日报道，据路透社调查显示，最大的石油出口国沙特阿拉伯预计将于1月提高其对亚洲买家的官方销售价格(OSP)，追踪基准价格走强，因为一些炼油商增加产量以满足冬季需求。
据亚洲炼油商的6位消息人士预计，沙特旗舰级阿拉伯轻质原油1月份的官方售价平均将上涨65美分/桶，他们的预测区间在50美分至85美分之间。
其中两位消息人士预测，沙特较轻级别的原油价格上涨幅度大于较重级别的原油价格上涨幅度，因为这些原油中含有更多的中等馏分油、汽油和航空燃料，这对本月的炼油商来说更有利可图。
根据路透社的数据显示，对现货原油的强劲需求推高了11月基准现货迪拜和DME阿曼原油期货的平均价差，较上月上涨约80美分。
印度石油公司(Indian Oil Corp)等炼油企业在11月份加紧原油采购，因为燃料需求恢复，而天气预报显示冬季将更加寒冷。
对于其他石油产品，亚洲11月份低硫燃油利润率的价差也有所加强，而汽油和石脑油则因供应充足而减弱。沙特的原油OSP通常在每个月的五号左右发布，这为科威特和伊拉克的价格设定了趋势，影响到每天运往亚洲的超过1200万桶的原油。
国有石油巨头沙特阿美公司（Saudi Aramco）根据客户的建议并根据产量和产品价格计算出过去一个月的石油价格变化后，确定其原油价格。

Saudi Arabia may raise Asia crude prices in January - survey
Top oil exporter Saudi Arabia is expected to raise its official selling prices (OSPs) for Asian buyers in January, tracking stronger benchmark prices as some refiners increase output to meet higher winter demand, a Reuters survey showed.
Six sources at Asian refiners expect the January OSP for Saudi flagship crude grade Arab Light to rise by 65 cents a barrel Two of the sources forecasted bigger price increases for Saudi lighter grades than heavier Strong demand for spot crude pushed up November's average differentials to Dubai swaps for benchmarks cash Dubai and DME Oman by around 80 cents a barrel from last month, data compiled by Reuters showed.
Refiners such as Indian Oil Corp stepped up crude purchases in November as fuel demand recovered while weather forecasts were pointing to a harsher winter.
For other oil products, Asia's cracks for very low sulphur fuel oil margins also strengthened in November , while gasoline and naphtha weakened due to ample supply. Saudi crude OSPs are usually released around the fifth of each month, and set the trend for Kuwaiti and Iraqi prices, affecting more than 12 million barrels per day (bpd) of crude bound for Asia.
State oil giant Saudi Aramco sets its crude prices based on recommendations from customers and after calculating the change in the value of its oil over the past month, based on yields and product prices.
