Behavior of Polyampholytes in Aqueous Salt Solutionfor this purpose as it produces a high viscosity in fresh water at a reasonable cost. However, anionic polyacrylamide rapidly looses its viscosity in solutions containing added electrolyte. In addition, polyacrylamides are sensitive to shear degradation.

A Review of Synthesis, Characterization, and Properties of Complex Polymers for Use in the Recovery Many processes that are basic to the extraction of natural resources are facilitated by addition of polymers. To be useful, the polymers must meet an interrelated list of chemical and physical properties as well as economic criteria. The chemical and physical properties demanded of the polymers are:

Vinyl Sulfonate/Vinyl Amide Copolymers as Temperature- and Salt-Stable Thickeners for EOR Flooding PIn 1985 enhanced oil recovery processes represented over 11.7% of total domestic crude oil production in Germany. Some 75% of this supplementary production was the result of steam processes, the remaining 25% was recovered using chemical flooding processes, in particular polymer flooding techniques.

Thermally Stable Acrylic Polymer for Profile Modification Applicationsultivalent metal ion.. The latter may be generated in situ from a redox couple, e.g., sodium dichromate/sodium metabisulfite or as a complexed reagent, e.g., aluminum citrate. This enables the gelation process to be retarded until the aqueous polymer solution has been placed deep into the thief zone.

Additionally the structure and HDV of the polymer must be tailored to allow permeation through the reservoir rock without entrapment, adsorption, or shear degradation.
