Mathermatical Modeling of Dynamic Mass Transfer in Cyclic Solvent Injection
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Canada Heavy Oil Technical Conference, June 9–11, 2015
Paper Number: SPE-174519-MS
... Abstract In a cyclic solvent injection (CSI) process, a solvent gas is cyclically injected, soaked, and released to produce heavy oil. Through this process the operating pressure is decreased and increased cyclically. This causes a dynamically changing pressure gradient across the solvent–oil...
