Abstract
Many heavy oil reservoirs in the world contain oil that has
limited mobility under reservoir conditions. In these reservoirs,
a small fraction of the oil in place can be recovered using the
internal reservoir energy through heavy oil solution gas drive
(primary production). An integral part of this process is the socalled
“foamy oil mechanism”, where oil is produced as a gasin-
oil dispersion. At the end of primary production, the bulk of
the oil is still in place, while the natural energy of the reservoir
has been depleted. In this work, we present experimental
results of foamy oil depletion at two different length scales, and
varying depletion rates. At the conclusion of primary recovery,
the potential for further non-thermal exploitation of these
reservoirs is explored. Results for waterflooding and chemical
flooding are presented, demonstrating the viability of these
techniques for heavy oil EOR. There are several displacement
mechanisms identified through the secondary and tertiary
processes that contribute to significant (although slow)
incremental recovery of heavy oil.
