Experimental investigation and rheological behaviors of water-based drilling mud contained starch-ZnO nanofluids through response surface methodology

The study of rheological properties is one of the essential aspects in designing drilling mud and its performance in operational conditions. The adding nanoparticles and natural polymers such as starch in drilling mud is the one way for modifying rheological properties. In this research, rheological behavior of a water-based drilling mud containing starch and ZnO nanoparticles were investigated and optimized. The rheological parameters were...
