The table shows the bit record for a well drilled nearby your current location: Tricone Bit Bit cost, USD Depth in, ft Depth out, ft А 2.500 2.800 4,800 B 8,300 8.900 9,850 Footage drilled. Rotating time, ft hr 600 29 950 39 1.650 81 8.900 9.850 11.500 с For the economic analysis, consider that the rig operating cost is $1,000/hr and tripping time is computed as 1 hr/1,000-ft (depth out). A bit company engineer wants to persuade you to drill the same interval (from 8,300 ft to 11,500 ft) with one single PDC bit run. The cost of the PDC bit is $50,000 What is the target ROP (ft/hr) the PDC bit must obtain?
