Daqing oilfield raises output through polymer flooding
The Xingnan area of Daqing oilfield exceeded its production target for oil recovered through polymer flooding.
Polymer flooding uses injected polymer to help move oil through underground rock.
The field is in a late stage of development, and some oil-bearing layers have not been drained evenly.
Staff at Daqing oilfield's Fifth Oil Production Plant use digital monitoring and detailed fracturing plans to target those layers.
Oil gained per tonne of polymer reached a record for this period, according to the company.
The approach aims to recover oil from areas that earlier production methods did not reach.
Daqing Oilfield’s Xingnan development area exceeded its planned crude oil output from polymer flooding.
Oil gained per tonne of polymer reached its best level for the same period on record, according to China News Service.
The oilfield’s No. 5 Oil Production Plant is using digital monitoring and detailed hydraulic fracturing to improve recovery.
The measures target uneven reservoir development and oil-bearing layers that have not been fully tapped.

Every tonne of oil from polymer flooding does not appear out of thin air.
