2-) Given the following data:
Drilling Fluid Density : 12 ppg
Well Depth: 10,000 ft.
Drill Bit Nozzle Sizes:
13-13-13
Pump Horsepower: 1800
Pump Volumetric Efficiency: 80%
Maximum Pump Pressure: 4,500
psi
Minimum Flow Rate: 350 gpm
Parasitic pressure losses of 2,173
psi and 1,388 psi are anticipated while circulating mud at flow
rates 500 gpm and 390 gpm respectively.
a-) Determine the parasitic pressure
losses when the bit hydraulic horsepower is maximum.
b-) Determine the optimum flow rate
when...
