The diesel fuel consumption rate (in United States gallons) for drilling at a depth of
1,200 ft is
q = 123 8 . = 18 2 . gal/hr
f
0 8156 8 33)
(. )( .
Using similar calculations as those given above, the diesel fuel consumption
rate for other drilling times (or depths) can be obtained.
Figure 5-11 shows the diesel fuel consumption rate as a function of drilling
time (or drilling depth) for this prime mover. The diesel fuel consumption rate for
this example is constant through the drilling time of 40 hours. This assumes that
the top drive power requirement is also constant over interval drilled.
