In February 1983, a hydrocarbon miscible flood (HCMF) was implemented in the South Lobe D-2A Pool, Fenn – Big Valley field in central Alberta. The pool had effectively watered out under the primary drive mechanism and its performance indi- cated a primary recovery of 48.8% of OOIP. Initial estimates suggested an incremental recoveryfactor of 15% by the tertiary flood.
