a nonionic polymer (polyacrylamide) used in flocculation, clarifying and even gelling acids and other brines. Very stable, but difficult to effectively break.

n: CH2=CHCOOM. Usually used to make polypropylene copolymer.

a resin polymerized from one of several sources: acrylonitrile, acrylic acid, methacrylic acid, etc.

n: a method of improved recovery in which alkaline chemicals such as sodium hydroxide are injected during a water flood or combined with polymer flooding. The chemicals react with the natural acid present in certain crude oils to form surfactants within the reservoir. The surfactants enable the water to move additional quantities of oil from the depleted reservoir. Compare chemical flooding, polymer flooding, water flooding.

n: A kind of polymer synthetised by oxirane and other organic compound.

n: The high polymer that has two kinds of different groups in molecule link. These two kinds of groups dissociate in water. One of the groups makes the polymer positive and another makes the polymer negative.

a copolymer. Acrylamido-methyl-propane sulfonate polymer.

a material that can quickly destabilize foam in a production fluid treating facility. Commonly needed after treatment with foamers, diesel, some polymers, some acids and gasified fluids.

n: The process that superpolymer is destroied by the microbe and macromolecule fractures to micromolecule.

breaking down alkanes by bacterial action. Common by psedomonis and ultramonis bacteria and other bacterial strains that digest parts of the crude oil structures. Useful for remediating oil spills or tank bottom residuals.

n pi: a group of polymers that can maintain or increase the viscosity of bentonite while flocculating other clay solids in the mud. With bentonite extenders, desired viscosity can often be maintained using only half the amount of bentonite that would otherwise be required.
