Conversions 1. Do the following conversions/ calculations: (6 pts) How much does a 1 kg mass weigh in Newtons? b. (6 pts) Convert that 1 kg mass to Ibm. And how much does that mass weigh in lb? c. (6 pts) Convert watts to horsepower. 2. Convert fresh water density (1.0 g/cc) into the following units: a. (3 pt) kg/m3 b. (3 pt) 1bm/ft3 c. (3 pt) Ibm/gal 3. (6 pts) A drilling mud has a density of 15 ppg (Ibm/gal). What is the pressure gradient in psi/ft? 4. (6 pts) The frac gradient for a reservoir is 0.7 psi/ft. What is the frac gradient in ppg? Power calculations - also show your work. 5 . (20 pts) Assuming the following data, calculate the required drill rig hoisting power in horsepower and in watts. 30,000 ft maximum drilling depth capability . 25 lb/ft drill pipe 125 lb/ft drill collars (assume using 500 ft of collars) . 25,000 lb traveling block . 5 ft/s maximum velocity 10 ppg drilling mud steel density= 8000 m 3 The following formulas will be needed. fluid density Bouyancy factor = 1- object density Bouyant weight = (dry weight * bouyancy factor) Power = Bouyant weight * velocity6. While drilling, the mud is being circulated at 2.5 bbl/minute. The surface pressure seen at the pumps is 2,500 psi. Hydraulic horsepower 2 flow rate >i
