Natural Resources committee  NRCan has done work investigating whether different types of crudes are more or less corrosive within pipelines. The results show that heavy crudes are heavy crudes, and there's no real difference in terms of the internal corrosion rates with different types of crude oils.

Natural Resources committee  Yes, I can talk about that. Maya, of course, is produced by Mexico. It's heavy crude, mainly from offshore fields. It has an American Petroleum Institute gravity of about 23 degrees and a sulphur content of about 4%. Western Canada Select, or WCS, is a blend of bitumen, synthetic crude oil, and diluent, which has an API gravity of about 22 degrees and a similar sulphur content to Maya.

Natural Resources committee  We produce the “Fuel Focus” report every two weeks, which looks at the input costs to refineries and at gasoline prices. It's a five-page report and has a lot of data and information. As my DG has said, the refineries in eastern Canada are paying global-type prices for their crude, for the most part.
