Abstract

A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which pivots radially outwardly from the tool upon tool rotation to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released and is stowed adjacent the housing by opposite tool rotation. Preferably the profile of the jaw allows it to stow closely against the housing for presenting minimal obstruction. More preferably, the jaw is formed independent of the housing and the bore supports differential pressure so that the tool can be installed above a rotary pump or as a part of an extended tailpiece.
