## Abstract

A drill pipe comprises a drill pipe body having a drill pipe body outer diameter and a drill pipe body inner diameter, wherein the drill pipe body outer diameter is from about 5.1-inches to about 5.4-inches and the drill pipe body inner diameter is from about 4.4-inches to about 4.6-inches; and a tool joint comprising a rotary shoulder box connection; wherein the drill pipe has an optimization ratio and wherein the optimization ratio is at least about 0.68 for a production hole from about 7⅞-inches to about 12¼-inches. Methods of using the drill pipe are also disclosed.
