Abstract
An improved cementing tool is presented which allows for relatively easy removal and insertion of the tool through the use of non-threaded low-torque connections. The cementing tool uses a combination of threaded connections and non-threaded, low-torque connections configured to create a stack of components including plug launchers, ball launchers and plug launch indicator/counters. Use of non-threaded low-torque connections allows for breaking down the tool by hand, requiring no special torquing equipment.
