Abstract
A high-strength side pocket mandrel for high pressure service having a full-opening bore throughout its length but having a bore of keyhole shape above its receptacle bore to provide minimal but ample space for operation of a kickover tool for installing devices in the receptacle bore and providing strengthened walls for withstanding greater forces which would tend to burst or collapse the mandrel.
