Systems and methods are disclosed for controlling a downhole tool by encoding a tool control signal in a fluid flow and obtaining a temperature response downhole. In an example, a system for controlling a downhole tool includes a signal transmitter, a signal receiver, and a controller. The signal transmitter is uphole of the tool to be controlled (e.g., at surface) and encodes the tool control signal by varying one or more fluid flow parameters of a fluid flow down a well. The signal receiver is positionable in the well in fluid communication with the fluid flow. The signal receiver detects a temperature response in the fluid flow resulting from varying the one or more fluid flow parameters. A controller controls the downhole tool according to the temperature response.

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.
