Summary:A seal assembly for a reamer tool positionable in a wellbore includes an annular seal disposed in a longitudinal bore of a tool housing of the reamer tool; an annular wiper disposed upstream of the annular seal in the longitudinal bore; and a tubular sleeve coupled to and movable with a drive mechanism disposed in the longitudinal bore of the tool housing. The tubular sleeve is disposed in a radial gap between the drive mechanism and a surface of the longitudinal bore of the tool housing. The sleeve includes a radial opening through a sidewall of the sleeve, and the tubular sleeve is slidably engageable with the annular seal and with the annular wiper as the drive mechanism is moved through the longitudinal bore of the tool housing.
