13. A method comprising:
lowering a dissolvable gauge cutter, a temperature sensor, and a pressure sensor through a tubular installed within a wellbore formed in a subterranean formation, the dissolvable gauge cutter, the temperature sensor, and the pressure sensor are dissolvable and made of an alloy comprising magnesium and at least one of zinc, aluminum, iron, tungsten, nickel, manganese, or copper;
dislodging, by the dissolvable gauge cutter, solids from an inner wall of the tubular as the dissolvable gauge cutter travels through the tubular to a specified depth within the wellbore to ensure a minimum inner diameter of the tubular;
measuring, by the temperature sensor, a temperature of a surrounding fluid as the dissolvable gauge cutter travels downhole through the tubular to the specified depth; and
measuring, by the pressure sensor, a pressure of the surrounding fluid as the dissolvable gauge cutter travels downhole through the tubular to the specified depth, wherein the dissolvable gauge cutter completely dissolves after reaching the specified depth.
