With the global crude oil production reaching peak production, or peak oil, the need for tertiary recovery
methods have been witnessing a rise in demand to recover the proportion of reserves which were previously unrecoverable.
At present, it is widely used in oil field for tertiary recovery
. The practice of field development has proved that polymer flooding is an effective method of improving oil recovery (EOR) and has become an important part of oil production in middle and later stage [1-3].
In the annual performance submission to the Alberta Energy Regulator by CNRL, they said that primary recovery on their leases has been between 5% to 8%, while incremental polymer flooding has increased tertiary recovery
to a range from 14% to 30%.
And if PDO is scaling back on tertiary recovery
projects, then it's a fairly safe bet that smaller producers will do so too.
"A lot of the offshore product is exported directly, avoiding pipelines that are the main target for siphoning aACA* also those interested in secondary and tertiary recovery
of fields the risks will be limited as well, given that the mature fields that require this type of investments are in the southeast of the country where the cartels have a lower presence," Petersen said.
Enhanced oil recovery is also called improved oil recovery or tertiary recovery
(as opposed to primary and secondary recovery).
Secondary and tertiary recovery
technologies now boast of a recovery factor of 60 percent to 75 percent, he said while inaugurating "IEF NOC-IOC Forum" in its third edition here yesterday.
Also known as tertiary recovery
, EOR allows up to 60% of a reservoir's original oil to be extracted.
methods (or enhanced oil recovery, EOR) involves the use of sophisticated techniques that alter the original properties of the oil.
Bradley: Tertiary recovery
is a major source of future oil supply, not just in the U.S., but potentially many places in the world.
Modern tertiary recovery
techniques will be required to maximise reservoir drainage as well as formations and treatment in less permeable reservoirs.
