Partially hydrolyzed polyacrylamide: enhanced oil recovery applications

Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.

Techniques for increasing the amount of oil recovered are thus being adopted to extend the capacity of oil reserves, whereby delaying the need to identify new giant fields. The global average for oil recovery from existing oilfields is only between 20% and 40%, less than half the recovery rates typically achieved in gas fields.

Development of a High-Strength and Adhesive Polyacrylamide Gel for Well

For a fast gelation, the pH of 5.0¨C9.0 is desirable to form a stable and high-strength gel to plug the pressure from downhole for a long time. Since the acidic environment is detrimental due to the corrosion to the internal wall of the wellbore, the pH of 8.0¨C9.0 is desirable for field application. 3.4.

Comparative Study on Enhancing Oil Recovery under High Temperature

In the polymer flooding operation, a high molecular weight water-soluble polymer, polyacrylamide or its derivatives, is added to thicken the displacing fluid, so as to reduce the mobility of the aqueous phase, enlarge the swept volume, and , consequently, to improve oil recovery efficiency. 4,5 Additionally, polymer adsorption onto the rocks decreases the permeability to water, and the

Nanofluids based on hydrolyzed polyacrylamide

Partially hydrolyzed polyacrylamide (HPAM) aqueous fluids in reservoirs produces a significant increase in the produced oil volume. However, the viscosity of these fluids is highly influenced by the temperature and salinity of the medium which is crucial in some reservoir conditions for the oil recovery.

The main role of polymers in field applications for oil recovery is to improve drilling fluids by increasing the viscosity of the aqueous phase, which eventually leads to improving the efficiency of sweep. Therefore, rheology is of great importance in studies of oil recovery from oil fields [9,10,11,12].
