Abstract

See full text

An apparatus to increase a diameter of a well bore includes a drill pipe and a first reamer and at least a second reamer. The second reamer is positioned diametrically opposed to the first reamer. A first plurality of cutting teeth are positioned about each of the first reamer and the at least a second reamer. 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. 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. At least a second plurality of cutting teeth are 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.
