    Abstract: Roller devices for passively or actively aiding in the conveyance of a toolstring through a well. The well may be of tortuous architecture and include a host of different corrosives. However, the roller devices are equipped with a cylindrical bearing based mechanism such as a journal bearing. Thus, these devices may be substantially less prone to exposure to corrosives. For example, they may be provided in a substantially monolithic circumferential form more readily shielded and/or isolated from such direct exposure.
