摘要:
A downhole tool is provided including apparatus for unsticking the tool from the wall or a borehole. The tool may include a housing defining a longitudinal axis and a sleeve coupled to the housing and mounted for rotation relative to the housing, the sleeve having an exterior surface including at least one projection extending radially outwardly with respect to the longitudinal axis. A transmission mechanism may be coupled to and adapted to rotate the sleeve, and a motor may be coupled to the transmission mechanism. A method for unsticking the downhole tool by rotating a sleeve is also disclosed.
