Intramolecular polymer complexes - viscosifiers for high ionic strength drilling fluids |
| abstract |
A new family of terpolymers based on acrylamide/sodium styrene sulfonate/methacrylamidopropyltrimethylammonium chloride has been found to be an improved viscosity control additive for water-bases drilling muds. The resultant muds display good viscosity characteristics, thermal stability and gel strength when formulated from the terpolymer intramolecular complex having the appropriate polymer concentration and salt level. |
