Methods for controlling the rheological properties of viscoelastic surfactants based fluids |
| abstract |
It was found that the addition of polymers to viscoelastic surfactant base system allows to adjust the rheological properties of the base fluid. Depending in particular on one side of the ratio of the concentration of added polymer and the concen-tration of viscoelastic surfactant and on the other side of the molecular weight of the added polymer, the same polymer - or the same type of polymer - may perform different functions such as viscosity enhancer, viscosity breaker or viscosity-recovery enhancer. |
