Russian refining rose to an all-time high in November 2005, as record high crude oil export duties prompted oil firms to send more volumes to domestic processing, Energy Ministry data showed.

The data showed Russian refineries processed 4.37 barrels per day in November, up from the previous highs of 4.24 barrels per day in October and 4.25 barrels per day in September.
Fuel oil and gas oil accounted for most of the increase, since production of higher-value light products such as gasoline was already close to capacity. Refiners will need to invest in costly upgrades to boost production of the higher-quality fuels.
The data also showed exports of gasoline and jet kerosene fell in November, as export duty on light products rose to a record $133.5 per tonne.
Gas oil and fuel oil exports also rose by 11 and 15 per cent.
