摘要： Methods, processes, and apparatuses for preparing and transporting bitumen. Bitumen may be prilled such that a bitumen product comprising a prill core and a non-stick coating is produced. The non-stick coating may comprise asphaltenes and the prill core may comprise bitumen, deasphalted oil, or both bitumen and deasphalted oil. The resultant non-stick coated prills have reduced adhesion to transportation vessels and other non-stick coated prills at a temperature below an adhesion temperature, facilitating transport.

摘要： A method of completing an injection well includes determining a volume of recoverable oil in each of a plurality of intervals along the injection well in a reservoir, and determining a target steam flow for respective ones of the intervals to facilitate recovery of the recoverable oil from the intervals. A quantity of steam outlets in devices along the injection well is determined for delivery of the target volume of steam determined for the ones of the intervals. The injection well is completed including steam injection tubing having the determined number of steam outlets for delivery of the target volume of steam to the ones of the intervals.
