Abstract: 

NOWADAYS THE PRODUCTION FROM PETROLEUM RESERVOIRS HAS A GROWING TREND OWING TO THE INCREASE IN GLOBAL CONSUMPTION DEMAND. DUE TO THE PRODUCTION FROM EXISTING RESOURCES THE AVERAGE DRILLING DEPTH FOR RESERVOIRS HAS INCREASED BY 27%. GEOTHERMAL GRADIENT AND LITHO STATIC PRESSURE OF THE OVERBURDEN LAYERS LEADS TO THE INCREASE IN BOTH TEMPERATURE AND PRESSURE WITH DEPTH. TO CONTROL SUCH PRESSURE AND ALSO TO EQUILIBRATE THE DOWN HOLE TEMPERATURE, THE DRILLING FLUID NEEDS TO HAVE OPTIMUM VISCOSITY TO WITHSTAND THE FORMATION PRESSURE AS WELL AS SUFFICIENT HEAT TRANSFER TO COOL DOWN THE DRILL BIT AND DRILLING STRING. IN THIS STUDY, THE NANO FLUID CONSISTING IN COPPER OXIDE NANOPARTICLES IN WATER IS ADDED TO THE DRILLING MUD STRUCTURE AND THE DUAL FLUID THEORY HAS BEEN APPLIED WITH THE NRTL MODEL TO INVESTIGATE ITS PROPERTIES. RESULTS OF THE EXPERIMENT SHOW THAT SUCH NANO FLUID CAN PROMOTE THE THERMAL PROPERTIES CONSIDERABLY AND INCREASE THE VISCOSITY OF THE FLUID TO A HIGHER EXTENT.
