description A section milling system may include an anchor secured to a downhole end of a coiled tubing. The anchor is configured to expand radially outward to set the anchor at a desired downhole position and restrain rotation of the coiled tubing. The section milling system also includes a reamer positioned downhole from the anchor. The reamer having extendable cutting arms configured to extend in response to fluid flowing through the reamer. Additionally, the section milling system includes a motor configured to rotate in response to fluid flowing through the motor, and rotation of the motor is configured to drive rotation of the cutting arms of the reamer to mill wellbore casing positioned adjacent the reamer. The section milling system further includes an actuation feature configured to move the reamer to mill along a wellbore in the uphole direction.
