Hydrolyzed polyacrylamide – Fly ash reinforced polymer
Polymer Injection is a mobility control enhanced oil recovery (EOR) method used to increase recovery beyond that of primary and secondary production mechanisms. One of the most used polymers in the hydrocarbon industry due to its cost, availability, and ease in handling is hydrolyzed polyacrylamide polymer (HPAM).

CA1073654A - Hydrolyzed polyacrylamide latices
ABSTRACT OF THE DISCLOSURE A process for recovering oil from subterranean oil-bearing forma-tions which entails the use of a water treating medium. The water treating medium comprises an acrylamide-acrylic acid copolymer formed by hydrolyzing a water-in-oil emulsion containing from 2-75% by weight of finely divided acrylamide polymer to the extent that between 0.8 and about 67% of the amide
Hydrolyzed polyacrylamide latices for secondary oil recovery According to the secondary recovery process, an aqueous flooding medium is injected into the one or more input wells which penetrate the oil-bearing formation in order to force the oil present within the formation into the one or more production wells which likewise penetrate the

Excessive water production from a producing gas well is substantially reduced by the injection of a hydrocarbon-diluted water-in-oil emulsion comprising a viscosifying polymer such as polyacrylamide, the injected emulsified polymer swelling on contact with connate water in the subsurface gas producing formation to restrict transfer of water therethrough toward the producing gas well.
Hydrophobically associating terpolymers of acrylamide
A partially hydrolyzed polyacrylamide (HPAM) copolymer was synthesized using a similar procedure as described in Example 1. Using the same reactor set-up, 75 grams of acrylamide, 80 grams of SDS and 2,425 grams of distilled water were mixed and sparged with nitrogen for 12 hours while heating to 50.degree.
A high-temperature (200°C)-resistant polymer gel system was developed from partially hydrolyzed polyacrylamide (HPAM), chromium lactate (CrL), and water-soluble phenol/formaldehyde resin (WPF
