Abstract
Controlling cable () tension and tool () position in a well () may include controlling either or both of tool position and cable tension independently by regulating reel () angle and flow rate of a fluid pumped over the tool. Thus, despite physical interdependency of tool position and cable tension, the tool may be controlled such that its position is changed while cable tension remains constant, or its position is held constant while cable tension is changed. In addition, actual downhole tool position, cable tension, and other actual values may be estimated using an observer.
