Project 2

Abstract

The purpose of this project was to design and create a hydraulic program to be used in

the calculation problems relating to the circulation of the mud fluid. The program would be

used to determine pressure drops and parasitic pressures at different depths and flow rates. It

was also to be used in the calculation of bit nozzles of optimal sizes. The project focused on

two depths, 6000 ft and 9000 ft both at flow rates of 259 gpm and 370 gpm. The project

attained its objectives. The hydraulic program was successfully developed in Excel and

calculated the required quantities. At higher flow rates the pressure losses were high

compared to pressure losses at lower flow rates due to the transition of the fluid flow from

laminar to turbulent. The project also found out that an increase in depth increased pressure

drop, whereas a decrease in depth caused a decrease in pressure drop. The optimal bit nozzle

sizes for depths of 6000 ft and 9000 ft were found to be two 10/32nds ...
