Reamer and bit interaction model system and method

A system, comprising:

• an interface being operable to receive a plurality of characteristic curves, each of the plurality of characteristic curves corresponding to a cutting structure, the plurality of characteristic curves including a weight on the cutting structures as a function of a rate of penetration of the cutting structures;
• and
• a processor being operable to:
• choose a first system including a first combination of at least two selected cutting structures, the first combination including a drill bit and a reamer;
• choose a second system including a second combination of at least two selected cutting structures, the second combination including a drill bit and a reamer, the first combination being different from the second combination;
• calculate a first system characteristic curve for the first system based on the characteristic curves corresponding to the selected cutting structures in the first combination, the first system characteristic curve comprising a sum of the characteristic curves for each cutting structure of the first combination;
• calculate a second system characteristic curve for the second system based on the characteristic curves corresponding to the selected cutting structures in the second combination;
• compare the first system characteristic curve with the second system characteristic curve;
• and
• select one of the first system or the second system based on the comparison.

A method, comprising:
