Drilling Fluids Manual (Amoco Production Company, 2010).pdf

Results of extensive research at both Amoco Production Research, Tulsa, and in the field show that penetration rate and its response to weight on bit and rotary speed is highly dependent on the hydraulic horsepower reaching the formation at the bit. Since the drilling fluid flow rate sets the system pressure losses, and these pressure losses set the hydraulic horsepower across the bit, it can be concluded that the drilling fluid is as important in determining drilling costs as all other “man-ntrollable” variables combined
