Method and apparatus for reaming well bore surfaces nearer the center of drift

An apparatus configured to be positioned in at least one of a drill string and a bottom hole assembly and adapted to increasing a diameter of a well bore, comprising:

• a drill pipe that includes a first end, a second end spaced apart from the first end, and a longitudinal axis that is aligned with a longitudinal axis of at least one of the drill string and the bottom hole assembly;
• a first reamer and at least a second reamer coupled to the drill pipe, wherein the second reamer is spaced longitudinally apart from the first reamer, and wherein the second reamer is positioned diametrically opposed to the first reamer on the drill pipe;
• a first plurality of cutting teeth positioned about each of the first reamer and the at least a second reamer, wherein a top of each successive tooth in a direction counter to a rotation of the apparatus in the well bore extends a radial distance from the longitudinal axis that is one of a) equal to a radial distance from the longitudinal axis of a preceding tooth and b) greater than the radial distance from the longitudinal axis of the preceding tooth, and wherein each tooth of the first plurality of cutting teeth is positioned at a different circumferential location about each reamer from any adjacent teeth of the first plurality of teeth;
• and,
• at least a second plurality of cutting teeth positioned about each of the first reamer and the at least a second reamer, the at least a second plurality of cutting teeth being spaced longitudinally apart from the first plurality of cutting teeth.
