US Classification:

1662525, 166 53, 175 40, 175 72, 702 9, 703 10

Abstract:

A system and method to model and analyze the mixing energies of high-yielding non-Newtonian fluids to prevent chemical lost circulation. Laboratory tests are performed under varying conditions from which data on the mixing energies needed to optimize the use of high-yielding non-Newtonian fluids to prevent lost circulation is obtained. This data is then applied to a non-linear mathematical modeling system that is capable of scaling the data to give a dimensionless value. This value can be combined with historic information to predict optimal flow rates and mixtures to prevent chemical lost circulation. This data may be verified by means of simulation, lab testing, or application to a full-size well.
