Enhancement of water based mud performance using iron oxide and polyanionic cellulose nanoparticles

Iron oxide and polyanionic cellulose nanoparticles (nano-PAC) have been previously used, but individually, to enhance the properties of the drilling mud. The use of iron oxide nanoparticles (IONP) showed significant enhancement in the rheology of the drilling mud while the use of nano-PAC has decrea...
