Effect of nanoparticles in cuttings transport perrformance of water based muds at eccentric drill pipe

One of the major issues for drilling operations is achieving effective cuttings transport, particularly in extended-reach drillings (ERD) with horizontal and highly deviated sections. The main objective of the present study is to investigate and compare the application of different nanoparticles (NP...
