Abstract:
1. A method comprising: providing a plurality of samples that comprises a base fluid and at least one deformable additive, the at least one deformable additive being at different concentrations in the plurality of samples; measuring a strain (γ) for the plurality of samples under exponential shear with a strain scale factor of 0.5; and plotting an exponential viscosity curve of an instantaneous exponential viscosity (η producing a treatment fluid additive for at least one subterranean operation selected from the group consisting of fluid loss control, wellbore strengthening, and zonal isolation, wherein the treatment fluid additive comprises the at least one deformable additive in a sample selected from the one or more samples that has a positive inflection point on the exponential viscosity curve at a strain of 500 or greater.
