Abstract
Thermal oil recovery operations, such as SAGD, result in waste heat that is typically released to the environment. Bitumen mining operations require heat input for heating fluids used in the mining process. A method and system of recovering heat from a thermal recovery operation for use in bitumen mining operation may include a heated donor fluid from a thermal recovery operation which heats an acceptor fluid for use in bitumen mining via proximal heat exchange using a power cycle or heat exchange module, such as an ammonia and water based Kalina® Cycle.
