Abstract
The role of the mud engineer or more properly drilling fluids engineer is very critical to the entire drilling operation because even small problems with mud can stop the whole operations on rig. Results also indicate the optimum velocity which shows the minimum amount of TDS using 450 cc of Fe2(SO4)3 is 90 rpm. So this may since of the higher amount of coagulant which reaches lower amount of TDS using smaller shear rates and lower mixing velocity in the fast reactor. Also, using 450 cc of FeCl3 and also, Al2(SO4)3 results low amount of TDS at 90 rpm of fast reactor mixing velocity. Using 150 cc of coagulant results 120 rpm as the effective mixing velocity of fast reactor and Fe2(SO4)3 as efficient coagulant obtain TDS= 0.348 g/lit. Also, a multi-layer feed forward BP network is optimized which is ninput −nhidden −noutput type. The number of neurons in input layer which is number of most effective independent variables is selected according to sensitivity analyzing. Number of neurons in hidden layer is found during network optimization.
