Barycentric Interpolation for Wellbore Fluid Property Prediction

The patent applies preliminary action by developing prediction models using historical fluid formulation data and laboratory test results before actual fluid design. The system pre-processes and stores relationships between fluid compositions and their properties (rheology, fluid loss, gel strength, etc.) in a database, enabling rapid prediction without repeating extensive laboratory testing for each new fluid formulation.

The patent uses copying by creating virtual representations of fluid formulations and their properties through computational models. Instead of physically testing each fluid formulation, the system copies existing formulation-data relationships from the database to predict properties of new formulations, significantly reducing the need for physical laboratory testing while maintaining prediction accuracy.

The patent replaces the mechanical system of physical laboratory testing with an information-based computational system. The prediction model uses computer algorithms to calculate fluid properties based on composition data, substituting physical experimentation with computational analysis. This substitution maintains formulation accuracy while dramatically improving design productivity and reducing laboratory resource requirements.

The patent applies parameter changes by transforming the fluid design process from physical experimentation to computational parameter analysis. The system varies composition parameters (chemical additives, concentrations, ratios) in the prediction model to optimize fluid properties, replacing physical formulation adjustments with computational parameter optimization. This enables rapid evaluation of multiple formulations without proportional increases in laboratory testing.
