Given the following information, determine diesel engine input power needed to hoist the drillstring and the corresponding fuel consumption rate in units of (gal/hr). 10 lines are strung between the crown block and the traveling block: Total well depth = 18000 ft. Drill collar weight = 120 lb/ft Drillcollar total length = 2000 ft Drillpipe weight = 35 lb/ft Tripping speed= 75 ft/min Mechanical efficiency of power transmission system (between diesel engine and drawworks) = 75% Diesel engine mechanical efficiency = 85%
