ABSTRACT:
An improved side pocket mandrel having a body comprising a one-piece main body section in which a main bore and a receptacle bore extend longitudinally therein and an upper body section having space therein for operating a kickover tool, welded together with a circumferential weld. In another embodiment, the machined main body section is welded by circumferential welds between upper and lower body sections. Additional embodiments are further disclosed having means therein for orienting kickover tools which are run and manipulated by wire line or pump down techniques and also having deflectors therein for deflecting regular well tools back into the main passage when approaching the receptacle from above and yet guiding flow control devices into the receptacle when such device is moved laterally into alignment with the receptacle by a kickover tool. Some disclosed embodiments have check valve means controlling flow between the exterior and the interior thereof.
Methods for constructing such side pocket mandrels and methods of welding tubular members, such as body sections of such mandrels, together with circumferential welds are also disclosed.
