ABSTRACT:
A side pocket mandrel designed primarily for controlling the flow of production fluid into a tubing string includes a sliding sleeve valve in the side wall receptacle for alternatively closing and opening the entry port into the receptacle. The sleeve valve is latched in its port-closing position, but is designed to enable removal from the receptacle bore for servicing; and a pulling tool is provided for removing the sleeve valve from the receptacle when desired. The sleeve is shifted to its port-opening position when a standing flow control valve is placed in the receptacle; and the standing valve has a large valve chamber and side entry and exit ports for the production fluid to provide for maximum flow. The standing valve provides a check valve into the producing zone, the valve closure member being a modified ball consisting of a cylindrical body with spherical ends and coacting with a spherical valve seat. During flow through the valve, the closure member is moved completely out of the flow path for maximum flow.
