SPE Annual Technical Conference and Exhibition, 2019
Abstract Non-thermal-solvent and thermal-solvent based heavy oil recovery processes are technologies in which solvent is used as either the main or the secondary agent, in conjunction with heating, for bitumen viscosity reduction. In these processes a hydrocarbon solvent is injected into the reservoir and produced back with the recovered

The Solvent Requirements for Vapex Recovery
SPE International Heavy Oil Symposium, 1995Abstract In both SAGD and VAPEX, recovery agents are introduced into the reservoir and these displace oil to horizontal wells located at the base. In each process it is desirable to inject at a pressure equal to or slightly below the pressure of the surrounding reservoir, so as to prevent flow of fluids to outside the recovery pattern.

Solvent transport, storage, recovery and disposal
1996In general, the economic benefits of operating on a large scale have ensured that solvents are manufactured at a small number of sites on facilities capable of annually producing several thousand tonnes of high grade material. However, the use of these chemicals is almost entirely separate from the site of production.
