Abstract
Methods and apparatus for removing deposits on components in a downhole tool are described. An example apparatus to remove a deposit on an inner surface of a flowline in a downhole tool includes a movable scraper disposed in a flowline of a downhole tool. The movable scraper is configured to selectively obstruct the flowline so that a fluid flowing in the flowline moves the movable scraper in the flowline. Additionally, the movable scraper has an outer surface configured to engage an inner surface of the flowline so that movement of the outer surface along the inner surface removes a deposit on at least a portion of the inner surface.
