VISCOELASTIC FLUID COMPOSITIONS, OIL FLOWABLE/OIL DESPERSION COMPOSITIONS, AND DRILLING FLUID COMPOSITIONS

摘要

Viscoelastic fluid compositions are provided that have improved properties for suspending particulate active ingredients. Methods for forming the compositions are also provided. The compositions preferably have a non-Newtonian behavior, so that the viscosity of the composition at low shear rates is suitable for keeping solid particles in the form of a stable suspension while also providing a reduced viscosity at higher shear rates (such as a substantially reduced or minimized viscosity) to allow for pumping, tank mixing, and/or distribution of the composition, for instance by spraying.
