Phase change material microcapsules for smart temperature regulation of drilling fluids for gas hydrate reservoirs

In natural gas hydrate drilling operations, hydrate decomposition can lead to serious wellbore instability. In this study, the use of encapsulated phase change materials (PCMs) is proposed to smartly regulate the temperature of drilling fluids to inhibit hydrate decomposition. PCM microcapsules cont...
