Abstract: A method of generating force in a wellbore includes setting an anchor on a body of a force generating device. The method also includes moving an actuator rod of the force generating device and apply tension to a cable connected with the actuator rod, wherein the force generated by the force generating device is the sum of the tension on the cable and the force generated by the force generation device.

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.
