Qualflood™ PAM Polymers for Oil Industry
Enhanced Oil Recovery
This process has been used to increase the efficiency of oil
recovery for tertiary floods. By adding the viscous polymer solutions to the
flood the efficiency of the volumetric sweep is increased, channeling and
breakthrough is decreased, overall oil recovery is increased. Typically 1mt of
polymer usage could gain an extra 150mts of crude oil. It is very cost
effective.
Qualflood™ series of product is developed to suit many
different temperature, saline, permeability or oil viscosity conditions for
enhanced oil recovery. The standard range Qualflood™ range of products
can be directly, or combined with a cross-linking agent, injected into the oil
stratum. These products can be used with an oil stratum temperature lower than
60°C and total dissolved solids (TDS) lower than 6,000ppm.

In oilfields where higher temperatures and higher TDS
levels are encountered, the Qualflood™-T series polymers can then
be used. These products are directly injected into the oil stratum and
cross-linked underground, and it is stable for temperature up to 110°C and TDS
up to 30,000ppm. If the product is cross-link treated prior to the injection,
it would be stable for TDS up to 150,000ppm. This could allow using the
recycled underground water for polymer preparation, which offers great saving
in water consumptions.
