Values in the table indicate that the insert tooth bit (1) was on bottom for a longer period, (2) drilled more footage, and (3) produced a lower cost per foot. The plot shows that had the steel tooth bit been pulled at its optimal life (6 hours and 34 minutes) it would have had a lower cost per foot: $34.05/ft versus $35.47/ft.

According to Arizona Geological Survey, Oil drilling in Arizona costs between $400,000 to $1,000,000, depending on the depth of the hole and its location. A rig capable of drilling most exploratory holes typically costs $8,000-15,000 per day. The bit must drill the 3,380 ft at an ROP of 13.7 ft/hr to equal the offset cost per foot of $28.46 for the same 3,380 ft. If an ROP is assumed, use the following equation to calculate the breakeven footage: Thus, in the above example, if we assume an ROP of 20 ft/hr, we have In this case, the bit must drill 1,627 ft to attain the breakeven point.
