Abstract
Methods for drilling in higher temperature rock formations such as geothermal formations with phase change material augmented drilling fluid include observing flow rate of the augmented fluid. Heat exchange between the annulus returning fluid and tubular fluid can be minimized thereby facilitating a cooler fluid for contact with a rock face being drilled. The cooling assists in pre-fracturing the rock face prior to destruction by the drill bit.
