Abstract
Systems and methods for predicting an efficient hole cleaning in vertical, deviated, and horizontal holes by developing a hole cleaning model that combines hole cleaning and drilling rate to optimize performance. Specifically by ensuring optimum mud rheology values that have an influence on drilling mud from the aspects of ECD, cuttings transport, shear thinning, and thixotropic, and developing an effective hole cleaning model by utilizing carrying capacity index (CCI) and cutting concentration in annulus (CCA).
