Abstract: Modular stabilizer tools may be used to reduce unwanted deflection of a wellbore and in effecting a desired change in direction of a wellbore in an efficient and inexpensive manner. As the diameter of a wellbore changes, the modular stabilizers plates may be configured to expand or decrease the outer diameter of a modular stabilizer tool without requiring removal of an entire section of the drill string. Each modular stabilizer plate of a modular stabilizer tool may be configured to align and affix to any one or more other modular stabilizer plates and may be of any size or shape. A site need only maintain a small inventory of modular stabilizer plates instead of entire collars, tools, or sections of a drill string. When any modular stabilizer plate, especially an outer spacer stabilizer plate, experiences wear or damage, it may be replaced without the requirement of replacing an entire collar.
