Abstract:
The disclosure includes a method of placing a wireline device in a deviated well having a hydrostatic column, the method comprising placing a positioning device in a wellbore of the deviated well, electrically powering the positioning device, moving the wireline device across a deviated region of the wellbore using the positioning device, wherein moving includes creating a driving force using the positioning device, and wherein the driving force is at least one of: a mechanical driving force and a fluid pressure driving force.
