Oil Pipeline Apportionment — Trans Mountain, Keystone and Cochin

The percentage by which each shipper's requested volume was cut in a month because total requests exceeded what the pipeline could carry, as the operators report it to the Canada Energy Regulator. Zero means every request was accepted. Shippers often request far more space than they expect to use, so a high figure means demand for space was heavy, not that the pipeline ran near empty. Enbridge's Mainline reports at many points along the system and has its own chart, measured differently. Cochin carries diluent into Alberta rather than crude out of it.
