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).
This patent describes a process for the secondary and tertiary recovery of oil from an oil-bearing subterranean formation having at least one input well and at least one output well which process includes the preparation of an aqueous solution of a polymer consisting essentially of a partially hydrolyzed polyacrylamide capable of meeting the
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 It is an object of this invention to provide an additive for use in the secondary recovery of oil from subterranean fromations which will improve the sweep of the oil from the subterranean formations. It is a further object of this invention to provide an additive which will
OIL RECOVERY PROCESS USING AN UNHYDROLYZED POLYACRYLAMIDE
What is claimed is 1. A process for the displacement of oil in an oil bearing formation comprising injecting into said formation an aqueous solution comprised of about 0.001 to about 10 percent by weight of a water-soluble partially hydrolyzed polyacrylamide and about 0.001 to about 10 weight percent water soluble unhydrolyzed polyacrylamide based on the total solution.
Abstract In present study the biodegradation of partially hydrolyzed polyacrylamide (HPAM) by bacterial strains isolated from Omani oil fields was analyzed. HPAMs are extensively used in oil fields for enhanced oil recovery operations. The produced
Polymers for enhanced oil recovery: fundamentals
The common expectation from polymer flooding is to obtain 50% ultimate recovery with 15 to 20% incremental recovery over secondary water flooding. Both naturally derived polymers like xanthan gum and synthetic polymers like partially hydrolyzed polyacrylamide (HPAM) have been used for this purpose.
Three coal samples, selected out of eight with well-characterized surface properties, were used in flocculation tests. A synthetic mixture of coal and silica was used in the selective flocculation experiments. The flocculants tested included: a hydrophilic polyacrylamide (PAM) and a semihydrophobic (F1029-D) flocculants and a totally hydrophobic latex prepared by emulsion polymerization (FR-7A
Proceedings of the Pulp and Paper Fundamental Research
Motivated by sustainability arguments there is a recent interest in forming of advanced structures in paper and paperboard. Therefore, in this paper, hydro-forming of papers and the effect of different fibre raw materials, beating, strength additives (PVAm), grammage and wet and dry papers have been investigated experimentally and numerically.

Microemulsion process for producing acrylamide-alkyl acrylamide copolymers Abstract. The copolymerization of water soluble monomers with water insoluble monomers can be effected by dissolving the water insoluble monomer into a homogeneous mixture of oil, surfactant, and cosurfactant and then diluting this with water containing the water soluble monomer to yield a predominently aqueous
