The primary feedstocks of our refineries are crude oil, condensates, atmospheric residues, hydrogen and a range of blend components such as pygas.  The main variables in the selection of a particular type of crude oil are price and quality,  with heavy/high sulphur, sour slates being cheaper than lighter/sweeter slates.  

Due to their technology and configurations, both our refineries are very flexible and able to process these low-cost, high-acid crude oils from domestic and deep sea sources.
