Enhanced heavy oil recovery using pyrrolidine solution as a bitumen emulsifier
Problem statement Bitumen is highly viscous because of its asphaltene content (e.g., 20 wt% n-pentane insoluble), and it is often immobile at reservoir conditions. Steam injection is widely used to recover bitumen, in which the latent heat injected can effectively mobilize the bitumen near thermal fronts. However, steam injection methods, such as cyclic...
