Claim One:
1. A method of predicting fluid properties comprising: determining an operational window for a well bore fluid system, wherein three or more vertices are selected that define boundary conditions for the well bore fluid system, wherein the boundary conditions comprise a mass ratio of a weighting additive to water and a mass ratio of a viscosifier to water; dividing the operational window into sub-windows; conducting a lab test to collect data at the three or more vertices of the operational window; and developing a model with a computer system, wherein the model is based at least in part on the data, wherein the model comprises predicted properties for a plurality of data points within the operational window, wherein developing the model uses Barycentric interpolation; selecting a wellbore treatment fluid based on the model; and introducing the wellbore treatment fluid into a wellbore.
