Abstract
The invention allows downhole shifting of one or more sleeves, having the same or different dimensions, while running a running tool on coiled tubing. The power stroker feature anchors the running tool to the body of the sleeve housing for proper orientation. Hydraulic pressure is used to stroke the sleeve. A feedback feature is provided to determine from the surface whether the sleeve has fully shifted. The stroking components are resettable upon withdrawal of hydraulic pressure and an emergency shear release is also provided.
